    - DataGrid ReadOnly Column BUG ! I´ve found a weird behaviour in the DataGrid: Scenario: ---------- I use a TableStyle with several standard TextBoxColumns within. One of that columns have the ReadOnly property set to true. In execution, select the text or a part of it in a cell inside the ReadOnly column. Then, do something that force the DataGrid to loose the focus and afterwards something else that changes its contents (DataSource changed, parent datagrid´s selected row changed, whatever...) After that, the text of the cell you selected is not refreshed, so it still appears in the DataGrid, even if all the rows of the DataGrid disappeared, the text is still there, by itself, looking at me and laughing. The text is refreshed if you give focus to the DataGrid again (by clicking on it or by manually calling .Focus() ). Im afraid I´m not using the correct terms to to search in the groups couse I couldn´t find much about the issue. I think it´s important enough to fix this, you guys out there ;) Thanks in advance.

    - searching in a listbox explorer style Hi If you have multiple items in a listbox, click into the listbox, then type for instante the letter "p", the first item whose text property starts with "p" will be selected. Pressing "p" again will jump to the next item starting with "p", etc. In Windows explorer, you can type multiple letters after each other, and if you're fast enough, they'll be taken as a search term together. For instance pressing "p" then "e" then "a" would lead to the first folder/file whose name starts with "pea" being selected. Is there any way to achieve this functionality in a Listbox as well?

    - OpenFileDialog and DataSet WriteXML strange problem Hi, I have a very strange problem which i hope someone can help shed light on. I have a Windows Forms application which provides data-entry UI. Data inputted is then stored into a DataSet which will be persisted into a XML file using the WriteXML method. The Dataset which contains a Filename data column (type = string); A user selects a file using the OpenFileDialog component. The file name is displayed in a textbox until the user clicks on the Save button. PROBLEM: If the file is selected using the OpenFileDialog.ShowDialog() method, the file name is added to the dataset, but it is not written to the XML file. However, if the filename is manually typed into the textbox, saving to XML file succeeds. Further tests shows that this problem only shows up in WinXP system. Machines running 2000 saves the XML file just fine. In the event of failure, no exceptions nor errors are shown. This is a very strange problem, any help will be very much appreciated!

    - Refresh current form to reflect culture change Hi everybody, I want to add localization support into my windows forms application. Basically, I create a menu item where users can choose a language of their choice. When users choose their preferred language, I want to update all the texts/labels on the current form UI to the new culture, instantaneously. For this, I have created a .resx file for each supported culture and in the event handlers for menu item's Click event, I change the CurrentUICulture property to the corresponding culture as follow: System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en-US"); However, when the program runs, nothing happens. So, I guess I must somehow force the form to reload itself. I've tried all the methods like Form.Update(), Form.Refresh(), Form.Invalidate(), ... but unsuccessful so far. Does anybody know the solution to this scenario ? Thanks a lot SuperKinhLuan Tag: Datagrid - set backcolour on individual cells? Tag: 80028

    - Panel controls autoscroll not working I have been having problems with a panel control since installing Windows XP SP2 and .Net framework 1.1 sp1. I have several forms in an application which contains several panels. One of the panels contains a panel which has controls added to it at runtime with the autoscroll property set to true. Some of the controls added are outside the visible range of the panel. Before the service packs the panel would have a scroll bar. Also when a child control outside of the visible range gained focus, the panel would autoscroll so that the control was visible. After the service packs, the panel scroll bar will not show up for controls added during runtime. If I add a control at design time outside the visible range of the panel, the scroll bar will appear. However, when the control gains focus the panel autoscroll position go to 0 instead of what is necessary to keep the active control in view. Has anyone had similar problems and/or know how to fix this problem? Thank you in advance. Tag: Datagrid - set backcolour on individual cells? Tag: 80011

I run the app (form) then drag an edge of the MDI larger than its start up size and scroll bars appear arround the mdichild that is resizing with it.

    - Inherit ListView Column Header Hi All, I have been looking at this for a little while now and can't figure it out. I was hoping someone could help. I needed to have an aditional property for the ColumnHeader object contained in the ListView Columns collection. I needed this property to map ListView columns to DataTable columns for a suedo databinding function. I though perhaps inherit from the listview and ColumnHeader objects. Here are the steps and code: STEP 1: Create a ColumnHeader object that inherits from ColumnHeader with the additional property Public Class DataBoundColumnHeader Inherits ColumnHeader Private m_BoundColumn As String 'new property Public Sub New() MyBase.New() End Sub <Category("Data")> _ Public Property BoundColumn() As String Get Return Me.m_BoundColumn End Get Set(ByVal Value As String) Me.m_BoundColumn = Value End Set End Property End Class STEP 2: Create a ColumnHeaderCollection object that inherits from ColumnHeaderCollection and shadows functions which assign and retrieve my custom DataBoundColumnHeader object Public Class DataBoundColumnHeaderCollection Inherits ListView.ColumnHeaderCollection Public Sub New(ByVal Owner As ListView) MyBase.New(Owner) End Sub Default Public Shadows ReadOnly Property Item(ByVal Index As Integer) As DataBoundColumnHeader Get Return CType(MyBase.Item(Index), DataBoundColumnHeader) End Get End Property Public Shadows Function Add(ByVal Column As DataBoundColumnHeader) As Integer Return MyBase.Add(Column) End Function Public Shadows Function Add(ByVal Text As String, ByVal width As Integer, _ ByVal TextAlign As HorizontalAlignment) As DataBoundColumnHeader Return CType(MyBase.Add(Text, width, TextAlign), DataBoundColumnHeader) End Function 'This should be public: but a conversion type error occurs Private Shadows Sub AddRange(ByVal Values() As DataBoundColumnHeader) MyBase.AddRange(Values) End Sub End Class STEP 3: Create a ListView object that inherits from ListView shadowing the Columns property to accept my ColumnHeaderCollection Public Class DataBoundListView Inherits System.Windows.Forms.ListView Private m_DataBoundColumns As New DataBoundColumnHeaderCollection(Me) <Category("Behavior"), _ DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public Shadows ReadOnly Property Columns() As DataBoundColumnHeaderCollection Get Return m_DataBoundColumns End Get End Property End Class THE PROBLEM: PROBLEM 1: This will not work unless the shadowed function AddRange is private and not public: The error is a typeconversion error PROBLEM 2: When I add the DataBoundListViewControl to a form and add some columns I get the following automatically generated code: 'Notice the System.Windows.Forms.ColumnHeader object Me.DataBoundListView1.Columns.AddRange(New System.Windows.Forms.ColumnHeader() {Me.DataBoundColumnHeader9, Me.DataBoundColumnHeader10}) Me.DataBoundListView1.Location = New System.Drawing.Point(72, 104) Me.DataBoundListView1.Name = "DataBoundListView1" Me.DataBoundListView1.TabIndex = 0 Me.DataBoundListView1.View = System.Windows.Forms.View.Details The automatic code generator creates an array of new ColumnHeader objects but assigns DataBoundColumnHeader ojects to items in that array. This is a little confusing. I really prefer it creates an array of DataBoundColumnHeader objects and then I could make my Private AddRange, Public.

    - Disappearing Window in Word Addin I am developing an addin for Word using C#. When the addin is activated, an always-on-top window is created with which the user interacts while editing a document. Sometimes, this window disappears. That is, you can no longer see the window, but it still exists. I have checked this through the debugger. The Visible property is still set to true, the size does not change, etc, but you can no longer see/interact with the window. The window disappears after closing a MessageBox that was created by the addin, but not always in the same place. This behavior occurs on Windows 2000 or Windows 2000 Server systems with Office 2000 installed. It does not occur on Windows 2000 or Windows XP systems with Office 2003 installed. Does this behavior sound familiar to anyone? Any help would be greatly appreciated. Tag: Datagrid - set backcolour on individual cells? Tag: 80005

    - Beginner's question about binding textboxes and adding records I've created an extremly simple form for testing. I want to add records using bound textboxes. I've created a connection by dragging a SQLdataAdapter on to the form and using the Wizard with no special conditions. (Just select * from a single table.) I've bound a few textboxes to the fields (4 boxes and a DateTimePicker to be exact). I fill the dataset on form load and I know I'm getting data then. My problem is this: Nothing I do will create a new row. I'm trying to add a record with what I thought were the usual means. Me.BindingContext(Me.DataSet31, "OrderH").EndCurrentEdit() Me.BindingContext(Me.DataSet31, "OrderH").AddNew() (The number of rows in the table does not increase and when I go to the Update call there is no row with DataRowState = Added.)

    - Forms designer load error. I added my own property (a double) to a derived component which can be edited in the property browser and is serializable. When I enter a small number such as .00001, the code generated in InitializeComponent() looks like this: this.StartTime.Increment = 1E-05; This compiles and runs fine, but the forms designer barfs and won't open the form. If I change the initialization to this: this.StartTime.Increment = 1.0E-05; then the form is happy. The form designer doesn't seem to understand and exponent without a decimal point. Any ideas? Here's what I'm using to get/set the value. protected double increment = 1.0E-6;; ...

    - Having derived forms recognizing the docking property of objects in the base form I have a base form where I docked a panel control across the header to act as a custom menu/tool bar. If I were to dock another control in the base form to the left side, it would recognize the first panel docked on the header, and therefore the 2nd panel would stretch from the bottom of the form to bottom of the 1st panel (1st panel being the one docked to the top which stretches from the left to the right side of the form). Ok that all works as expected. now I remove the 2nd panel from the base form as it was just a test to see that the docking was working correctly. Now I build the project and go to a form that's derived from this base form and I dock a control to the left side of the form. Instead of this left-docked control stretching from the bottom of the header panel (which is part of the base form and docked on top) to the bottom of the form, it stretches all the way to the top of the form and overlays my custom header (which is part of the base form). Is there anyway to change this behavior for a control docking in a derived form and recognizing the docking of a control in the base form?

    - VB.NET Application on File Share Cannot Be Updated I have a VB.NET application that I have deployed via UNC file share. Everything works fine after the users run the small MSI that sets the appropriate trust level for the URL. The problem I am running into, however, is that I cannot push updates out to the server. When I attempt to copy a newer version of an assembly, I get a File Sharing Violation error. What gives? I thought (and verified) that the EXE is downloaded and run in a local process on the user's machine? When I look in task manager on my machine, the application shows up (it does not on the server with the file share). I used ProcessExplorer on the server, and it seems that there are 3 references and 1 handle to each of the assemblies that comprise the application. Doesn't matter how many users are currently running the application. It always shows 3 references and 1 handle. Again, this makes no sense to me and my understanding of how NTD is supposed to work. Maybe my understanding is wrong? I have read everything I could find on deploying applications via file share, and I have not seen anything about problems copying updated assemblies out to the share. Any insight that anyone might have is greatly appreciated. I have some critical updates that I need to get moved out as soon as possible.

    - How to yield the primary thread to some other task? Hi, I'm trying to create a method on my windows form that starts a multi-threaded task, waits for it to finish, and then returns. To be more precise: the form has a LoadUrl() method. This method calls the Navigate() method on the form's embedded WebBrowser control, and then does a WaitOne() on a ManualResetEvent. This ManualResetEvent will be Set() from WebBrowser's DocumentComplete handler when loading is done. So, what happens is this: when Navigate() is called, the web browser starts the download in a secondary thread and returns, thus jumping to my WaitOne() call where I wait for it to finish. While downloading, the browser wants to update the UI, which has to be done from the primary thread. But no dice, the WaitOne() call is blocking it. Now, I must do some kind of Wait() on the primary thread because I want to return from the method only when the operation is complete. But, I somehow have to wait without blocking this thread. Is this possible? It seems that the windows form has a solution to this. How does the form manage this primary thread so it knows how to do BeginInvoke, for example? Do I need to use the message loop or something? Any hint is welcome. Thanks in advance! -- Boris Drajer <boris.drajer@do.not.s.p.a.m.micro-bs.com> Tag: Datagrid - set backcolour on individual cells?

    - Emailing from a Visual Studio.NET Application (Basic) I'm sending eMail messages from my Visual Basic.NET application. Creating a System.Web.Mail.MailMessage and sending it with SmtpMail.Send works fine, but I'd like to take it a step further and hook up with the correct Mail Server automatically, or, even better, deliver the message into the clientÂ´s actual eMail application so he can use his address book to select the recipient, etc. Can anyone point me in the right direction? At least as far as telling me how to get the name of the Mail Server, if any, that the user is hooked up with. As far as plugging into the Mail-client the user is using, perhaps that's a lot of bother since the different clients ,Outlook, Outlook Express, and (I shudder to mention it) Non-Microsoft mail clients may not accept the same type of Message-object. Still, I'd be grateful for any input. -- Gudmundur Karlsson Iceland Tag: Datagrid - set backcolour on individual cells? Tag: 79938

    - Transparent Label I have a form that has a picture box with an image. I will also me placing labels on this form in front of the picture box. I want the picture to show through the labels. I would like the labels to be transparent. I have tried setting the background color of the label to transparent, but all it shows is the background color and you can not see the image behind it. Is there any way to do this? Thanks, -- Eric Renken Demiurge Software LLC http://www.demiurge.us Tag: Datagrid - set backcolour on individual cells? Tag: 79937

    - New Problem with Always on Top Thank you for you help with the Always on Top issue previously posted. It worked great. But, I have noticed that when I call a different form using "ShowDialog" that the clipboard is still on top but I cannot access it. Is there a way to make MyClipboard not effected by the other forms that are displayed using "ShowDialog". I am looking to copy information from Frm2.ShowDialog into MyClipboard and paste it into Frm3.ShowDialog from MyClipboard... Thanks. Chuck Tag: Datagrid - set backcolour on individual cells?

    - textbox maxlength Hi, I looked everywhere for a reference to this, and I'm surprised that no one else (apparently) has run into this problem. I am using a textBox to collect/display messages as they are created in my system. I append them to the current Text contents using the AppendText() method. I never had problems with this until I moved to studio 2003 with SP2. Now, no matter what I set my maxlength to (0, 500K, etc ...), the AppendText() stops working once the buffer size reaches 32k. I'm sure it has something to do with the SP2 patches related to overflowing buffers, but I have no idea how to fix this (I definitely want to be able to put more than 32k into the textbox) Any ideas ? thanks, mark Tag: Datagrid - set backcolour on individual cells?

    - Winforms FAQ Datagrid Combo? I have used this example to embed a bound combo within a datagrid. It works very well, but with one exception. If the user selects a value from the list, the selected value is not actually shown until the control loses the focus. It always displays the previous, or first entry in the list. Once the control loses the focus, the correct value is displayed, but it is a little confusing. Any suggestions as to how I can get the display to update correctly? The code can be found on the winforms site. Cheers, James Tag: Datagrid - set backcolour on individual cells? Tag: 79915

    - IESourcing Problem w/ Threads Hi, I have a Windows Form that I embed in a HTML file. The Form has a TextBox and a Button. For simplicity sake, I am testing using a timer program, that should display the elasped time on the TextBox. I have a secondary thread that runs an infinite loop and every second updates the TextBox (using MethodInvoker). And also pops up a messageBox (I added this later to see if the thread runs). The Button is used to manually update the TextBox, from the main thread. I tried this on my local computer, running the HTML file in IE, and it worked perfectly. The TextBox updates automatically, the MessageBoxes pop up. Now, I tried the same thing from a computer on the network, it loads the form fine, but doesn't update TextBox automatically, and no MessageBoxes come up either on the client or the server. I don't know if the thread even started at all. However, the Button still works, if i click it, the textbox gets updated. Any ideas on what I'm doing wrong?

    - Order of Events on Form Creation This seems a really basic question but I can't find an answer in the help file, perhaps I'm looking for the wrong thing? I want to load the previous settings for my app which will indicate window size and position. I can't do it in the load event because the form doesn't actually exist (or is not visible) at that point. I put it in the form activate event with a flag so the settings are only applied once but this seems a bit clumsy. Is there an 'on first activated' or 'on first show' event that I could us. I am currently trying 'OnCreateControl' but I am not sure that makes sense. Many thanks. -- Jeff Gaines Damerham Hampshire UK Tag: Datagrid - set backcolour on individual cells? Tag: 79908

    - AxWebBrowser and WM_PRINT unexpected failures I'm trying to capture thumbnails of pages visited in a VB.Net app, in circumstances where the window containing the AxWebBrowser is often not on top. For this reason, I'm using SendMessage of WM_PRINT to the browser control's hWnd. (Also tried sending to a panel containing the browser control, with no improvemtn) The code itself essentially seems to work fine, because it captures the thumbnail of the first page that the control visits. But if the window containing the browser is then navigated BY THE USER CLICKING A LINK, rather than by doing a new Navigate2, subsequent calls to the routine just return a blank white bitmap with no content. Starting again with a new location reached by Navigate2 goes back to getting a valid bitmap. Clicking a link on the page breaks it again. Sadly, cancelling all navigation events and inserting coded Navigate2 to the same destination does not work either as a workaround - it results in a very intermittent solution. Any ideas? The actual code used is the following (huge swathes of error checks omitted) Private Sub PrintWindowToDC(ByVal hWnd As IntPtr, ByVal hdcDest As IntPtr, ByVal Width As Integer, ByVal Height As Integer) Dim hDC As IntPtr = GetDC(hWnd) Dim hDCMem As IntPtr = CreateCompatibleDC(hDC) Dim hBmp As IntPtr = CreateCompatibleBitmap(hDC, Width, Height) Dim hOld As IntPtr = SelectObject(hDCMem, hBmp) SendMessage(hWnd, WM_PRINT, hDCMem, PRF_CLIENT Or PRF_CHILDREN) BitBlt(hdcDest, 0, 0, Width, Height, hDCMem, 0, 0, SRCCOPY) SelectObject(hDCMem, hOld) DeleteObject(hDCMem) DeleteObject(hBmp) ReleaseDC(hWnd, hDC) End Function Public Function GetControlAsBitmap(ByVal ctl As System.Windows.Forms.Control) As Bitmap Try Dim g1 As Graphics = ctl.CreateGraphics() Dim tempImage As Bitmap = New Bitmap(ctl.ClientRectangle.Width, ctl.ClientRectangle.Height, g1) Dim g2 As Graphics = Graphics.FromImage(tempImage) Dim dc2 As IntPtr = g2.GetHdc() Dim rv As Int32 = PrintWindowToDC(ctl.Handle, dc2, ctl.Width, ctl.Height) g2.ReleaseHdc(dc2) Return tempImage Catch e As Exception MsgBox("Failure during getcontrolasbitmap", MsgBoxStyle.OKOnly, "Error") End Try End Function Private Function DoAbort() As Boolean MsgBox("I got an abort") Return False End Function Private callback As New Image.GetThumbnailImageAbort(AddressOf DoAbort) Public Function GetControlAsThumbnail(ByVal src As Control, ByVal Width As Integer, ByVal Height As Integer) As Bitmap Dim bmp As Bitmap = GetControlAsBitmap(src) Dim thumb As Bitmap = bmp.GetThumbnailImage(Width, Height, callback, IntPtr.Zero) bmp.Dispose() Return thumb End Function Tag: Datagrid - set backcolour on individual cells?

    - ListView Hot Tracking - missing functionality Tribe, Looking to see if anyone has coded up hot tracking for listbox or listview controls. Essentially it you do this: ListViewItem hotListViewItem; private void listView1_MouseMove(object sender, MouseEventArgs e) { ListView lv = (ListView)sender; ListViewItem item = lv.GetItemAt(e.X, e.Y); if (item != null) { item.BackColor = Color.Wheat; if (hotListViewItem != null && !hotListViewItem.Equals(item)) hotListViewItem.BackColor = Color.White; hotListViewItem = item; } } You can make the rows track hot BUT there is an awful lot of flicker when you do this. Anyone done this kind of thing and found an alternative method? Regards, Dave Cline ~bangeye.com~ Tag: Datagrid - set backcolour on individual cells? Tag: 79904

    - How to have MainMenu be parent of Control object I would like to have a control I have created have a System.Window.Forms.MainMenu as its parent. The menu will always have lots of available space on the right side and I want to take advantage of this. I tried to using the SetParent API but my control is not visible, even though it seems to be in the right place. I also tried using MyControl.BringToFront() in case this is a zOrder issue. I see that in PowerPoint there are maximize/minimize buttons appear in the exact place that I want my control, so it must be possible.

How do I set the background colour on an individual cell in a datagrid?

All I want to do is iterate through all the cells and if a cell has a
certain text value ('Unbooked') colour the background in red...
