    - DataGridView CellValueChanged event not firing I have a DataGridView that is bound to a list of objects through it's datasource property. If a cell in the grid is changed by editing directly in the cell I get a CellValueChanged event. If the value is changed in the underlying object that causes the cell in the grid to get changed then the CellValueChanged event does not occur. Does anyone know of a way to detect a cell value changing for both cases? I would like to detect the value change without leaving the row since I am trying to give immediate visual feedback regarding the validity of the data being entered and don't want the user to have to leave the row to find out if data in a cell is valid.

    - Question about SizeDataGridColumnToContent function... Using C# string xmlfile = "appsettings.xml"; DataSet ds_login = new DataSet(); ds_login.ReadXml(xmlfile); dgConnection.DataSource = ds_login; dgConnection.DataMember = "Connection"; SizeDataGridColumnsToContent(dgConnection, 1); The function works the way it is suppose to for every other datagrid I have. But for the one bound to the dataset with the XML I get an extra column added. the column is Connections_Id where Connections is an element name... The column DOES NOT show up if I don't use the SizeDataGridColumnsToContent function. here is the function: public void SizeDataGridColumnsToContent(DataGrid dataGrid, int nRowsToScan) { //first check to make sure the DataGrid has a valid datasource if (dataGrid.DataSource == null) { //it does not return; } // Create graphics object for measuring widths. Graphics Graphics = dataGrid.CreateGraphics(); // Define new table style.

    - Select a row of a DataGridView control with a certain column value Hi all out there, how can I select a row of a DataGridView control with a certain column value? What I need is something like a "RowDataBound" event, but I did not found this functionality in the DataGridView control. Background: I've got a DataGridView connected to a BindingSource. The User changes the sorting and then selects a row and hits the Edit button. Another form opens in which the user edits the detail data. If the detail form is closed, the data of the first form should be updated and then the originally selected row should be again selected (more exactly: the row with a certain value in a column, lets say where id=27). Thanks a lot for your help Ulrich Tag: ListView sort only sorts on paint? Tag: 103774

    - Tooltip Font Hi all, I'm writing a program where I have to draw custom tooltips onto a control through OnPaint. I've figured out how to get the text color and the box color (KnownColor.InfoText and KnownColor.Info), but I can't find anywhere how to figure out what the font is. I've looked through the WinAPI and others...maybe I'm just missing it, I dunno. Seems like it should be there somewhere, though. (These are what the user would set through the display settings in Windows.) Thanks in advance for any help. Tag: ListView sort only sorts on paint? Tag: 103756

    - DSOFramer and .NET Menus Apologies for the cross-posting - not sure where best to post...... Okay, this might be a shot in the dark since there are very few (positive) postings regarding the DSOFramer control but I'll give it a shot posting my problem anyway.... I'm trying to use the DSOFramer in a Visual Studio 2005 Windows Forms project (using C#). The configuration is simple. Using the standard tools provided with Visual Studio I have a main menu at the top with a toolbar just under it. A status bar is docked to the bottom and in the middle docked "fill" is the DSOFramer control. I am loading an Excel spreadsheet into the DSOFramer control. Here's the problem: 1. Click the "File" menu item from the main menu in the Windows Form (not the File menu in exposed by Excel). 2. Leave the menu in the expanded, dropped-down state. 3. Click anywhere on the Excel spreadsheet in the DSOFramer control. 4. The menu DOES NOT collapse. I have tried a number of combinations: .NET 1.1, third-party menu controls. Nothing works. The only control combination that does work is using Visual Studio 2003 and using the standard MainMenu control provided by Visual Studio. This seems to work okay HOWEVER, this control is very bland (does not allow for command icons) and is not useful for my project. In order to debug the problem I have also tried the following: 1. Capture EVERY event exposed by the DSOFramer control. No events are fired (such as Leave and Enter) when I click on and off of the hosted spreadsheet. 2. Ran the program using Spy to see what Windows messages were being sent. It appears WM_NOTIFYPARENT is sent but apparently .NET 2.0 ignores it (as does .NET 1.1). I'm no expert on Windows messages so perhaps I'm missing something rather than .NET! Any and all help is much appreciated. Tag: ListView sort only sorts on paint? Tag: 103753

    - Custom title bar drawing Hello, I'm trying to make a skinned application, so i'm overriding the paint methods of the controls. Concerning the painting of the form itself, it seems that there are 2 options: - Making the form borderless (FormBorderStyle to None), and building our own custom window title bar, but just think that this needs some useless work as we have to rewrite some window functions (move, resize, ...). Moreover, when maximizing the window, it makes it fullscreen. - This lead me to the second option which was to use the non client area painting by catching the WM_NCPAINT message in the WndProc method. With the help of some Win32 functions, i paint on the form (FormBorderStyle to Sizable) but something weird happens, the system buttons on the title bar redraw themselves, for example, when i move the mouse over the window. So they appear on the custom painting... Does someone have an idea of what happens with the maximize/minimize/close buttons and/or have a workaround for the second option ? Cannot find which message makes the buttons to be repainted. Or is the first option the best solution to make a skinned application ? Thanks for your help!

    - Keeping ToolStrip inside the same ToolStripContainer I would like to use multiple ToolTripContainers in my Form. I would like the ToolStrips in each ToolStripContainer to be freely movable within its container, but I would like to enforce a rule such that ToolStrips cannot be dragged from one ToolStripContainer to another. I am encapsulating each ToolStripContainer within a user control for several reasons, code reusability and layout simplicity being the main ones. I was hoping to simply implement a QueryContinueDrag handler in my UserControl but it does not seem to be getting called as I drag the ToolStrip around the screen. I'm using VS2005, .NET 2.0. I'm a veteran MFC programmer, been working with .NET for a couple of months - this is the first thing I've come up against where I wasn't able to find a solution with a little elbow grease!

    - Databinding: "BindingSource - field" syntax Hi, I have a question regarding databinding via the Visual Studio 2005 form designer. What I wanted to do is not a very good practice, it was just "quick and dirty" in really small application. I had a WinForms form with a typed dataset and a lot of controls bound to it via BindingSources. Because a lot of these fields are optional, and I wanted to clean the form up, I added a little button invoking a second (modal) form containing those fields. The latter only contained a BindingSource that got hooked up to the typed dataset on the main form (by passing a reference at creation) in runtime. (I passed the entire dataset because i needed a few tables with reference data). Knowing that the schema of the dataset will never change again I just wanted to bind the controls on the second form to the bindingsource in design time. Of course, the designer can't provide me with DisplayMembers, etc... I found that it was possible to manually set the DataBindings property for Text and Tag using the " bindingsource - field" syntax, the correct code is generated. For other fields, e.g. SelectedValue in a combobox, this is not possible via the properties window. I am curious now, is this a bug in VS2005 or is this supported? If so, why doesn't the "bindingsource - field" syntax work for all properties? Tag: ListView sort only sorts on paint? Tag: 103697

    - How to clone a refrenced type object? Hello I am developing a utility to be reused in other programs. It I have an object of type Control (a TextBox, ComboBox, etc.) that other programmers use it in applications. they may set some of properties or assign event handlers.

    - Hide form from Alt-Tab when first run Hi All, I would like to start a VB.Net 2.0 app minimised to the tray area. I use the NotifyIcon component, set the form to start minimised by adding this to the form.load event Me.WindowState = FormWindowState.Minimized Me.Hide() and set the notifyicon component property to visible, so it shows in the tray area. I have also set the showintaskbar property of the main form to false. All seems to work well when I run the app; the form does not show on the taskbar, and I can see the notifiyicon's icon image in the task bar. The problem is that the form icon is visible in the alt-tab switcher list. However, if I double click the icon in the taskbar, which runs this code in the notifyicon doubleclick event handler Me.Show() If (Me.WindowState = FormWindowState.Minimized) Then Me.WindowState = FormWindowState.Normal Me.Activate() End If NotifyIcon.Visible = False and then minimise the form, which runs this code in the form.resize event handler If (Me.WindowState = FormWindowState.Minimized) Then Me.Hide() NotifyIcon.Visible = True then now the form icon does not appear in the alt-tab switcher. I don't understand what is happening when the form is first shown, that is not happening when I restore and minimise the form. I have looked in these newsgroups and on the net but I could not find the answer, so any clues as to how to accomplish hiding the form from the alt-tab list when it first runs would be much appreciated.

    - Form Validate I'm not getting the validation behavior I'm expecting in my application. My form has a TabControl which, among other controls, contains a ComboBox. The form also contains a BindingNavigator control to work with the BindingSource. The ComboBox is bound to another binding source. The ComboBox has a DataSource from which its item collection is filled and its ValueMember and DisplayMember properties are set. The ComboBox DropDownStyle is set to DropDownList (so that the user must select from the list, and cannot enter anything else not in the list.) In the form's class, I added a method to handle the ComboBox Validating event. In the form's Save Button I call Me.Validate(). When I set the form's AutoValidation to EnableAllowFocusChange I expect that the ComboBox Validating event will be raised when the Save button is clicked and Me.Validate() is invoked. Instead, the ComboBox Validating event is raised when the ComboBox looses focus, even if the SelectedIndex has not changed. However, it does allow the focus to change, even if the Validating code executes an e.cancel. Am I correct in what I'm expecting? Should the ComboBox Validating event be raised when the Save button is clicked and I invoke Me.Validate()? Thanks, Bren Tag: ListView sort only sorts on paint? Tag: 103682

    - Writing to Standard Output from a Windows Forms application I have a very simple Windows Forms application that I am enhancing to also operate in command line mode. This seems simple enough... add some command line arguments so the user can specify the desired behavior without using the GUI and things should be fine. There is only one problem... how do I get output back to the command line user? The existing application writes the console with Console.WriteLine, but when the application is a Windows Forms application, this just consumes the output. It seems like the solution would be to set Console.Out to reset the Console Out stream to the real standard output stream, but I can't quite figure out how to do this. I realize Microsoft has made the assumption that a Windows Forms application never has to write to standard output, but this is not the first time I've had the need to do precisely this. Any pointers (I'm afraid all of my searches have been unsuccessful)? Finally, if indeed this is not possible, how would you suggest I go about implementing an application that can be driven either from command line arguments or its GUI? One architecture that certainly would work would be to have the intended command line be a console application, and if no arguments are present, then launch a second application that is the Windows Forms application. This certainly would work, but it sure seems a very complex solution to what is really a simple application. -- Sent via .NET Newsgroups http://www.dotnetnewsgroups.com Tag: ListView sort only sorts on paint?

    - Listview using up GDI resources I am using a windows forms listview control in my application. The listview is created with 2 columns and filled in with data on the Load Event of the form. At that point, the user is supposed to select an item from the listview. It seems that when the Listview control has the focus, the user can use arrow keys, keyboard letters etc to move from one item to another. Also the user can click on an item to select it. This seems to be operating properly in Windows 2000 and XP. On windows 98, this same application quickly uses up all of the GDI resources. My understanding of this problem is that every time the selected item of the listview is changed the control redraws itself. During the redraw it allocates memory for something (possibly to create a GDI drawing pen). It seems that it is not releasing the memory cleanly ie waitng for the garbage collector to release the resource. If that doesnt happen in time (before the next redraw) the GDI resources start to get used up. Is there any way to prevent this from happening??? Tag: ListView sort only sorts on paint? Tag: 103678

    - Text written with TextRenderer overwritten by other Controls? Hi everyone. I'm trying to write text to a Windows Form with TextRenderer.Drawtext, and it works fine - until I select an item from the Menu (System.Windows.Forms.MenuStrip) above it - at which point any text in the Form area underneath where the menu drops down gets erased. Here's the code I'm using to write to the Form - from a method within my Form class: Graphics g = this.CreateGraphics(); TextRenderer.DrawText(g, "Some Text", this.Font, new Point(10, 50), SystemColors.WindowText, TextFormatFlags.Default); If I put a Text Control on the form at design time in VS05, that Text Control DOESN'T get overwritten. So, text that I'm adding manually at runtime with TextRenderer appear but gets stomped on by other Controls, while Controls (eg: TextControl) added at design time are preserved. Any ideas? I'm stumped and assume there's something that I need to call in terms of Suspending Layout or Resuming or something like that, but no idea what.

    - CHM file and webbrowser component Hi group, I want to show a particular html page from a chm file in the webbrowser component (.NET 2.0). It works if I have the chm file on disk and make the webbrowser navigate to it via the mk:@MSITStore url (i.e. webbrowser.Navigate("mk:@MSITStore:C:\foo.chm::/start.html")). Now I want to embed the chm into my assembly and load it from there directly into the webbrowser component (without storing it temporarily on disk). I thought I could use webbrowser.DocumentStream and set it to the stream of the 'chm resource'. But how can I tell the webbrowser that this stream is a chm and he has to navigate to a specific html page. Perhaps there is a completely other aproach. Any hints are welcome.

    - Problem with WebBrowser control and Flash Hi, We have a problem with "hosting" a website in our winform applcation. To show the website we use the standard .NET 2.0 WebBrowser control. Our site includes a page which includes a Shockwave Flash control. The flash control reacts to a OnRelease event. The problem is that this event is not working inside the WebBrowser. If we load the page in internet explorer there is no problem. To demonstrate / review the problem I made a new Windows application with one form that has a WebBrowser control. Via the properties of the WebBrowser control I let it navigate to "http://freeschool.dreamhand.net/flash/demo/demo_demo.html". This page demonstrate teh OnRelease / Click events. Notice that you can click the circles in the "Demo Movie" Example and only ONE movie is loaded. If you load the same page in Internet Explorer each butoon loads a movie. So my conclusion is that when you host a web page in the WebBrowser control SWF is not working properly. Does anyone have a solution for this strange problem?

    - Panel doesn't show scroll bars Perhaps one of you geniouses can help. I have a panel whose AutoSize = true. This Panel is originally empty when the program starts, and it is programtically populated with my own User Control. The User Control is inherited from a Panel itself.

Has anyone notices this behavior?

I have a composite control that contains a listview. I've created my
own listviewsorter class that works just fine. As items get added (in
this case - a very small #, less than 40), I repaint all items
background to white, sort, and perform a colorization.

The code was supposed to colorize some things in an alternating
pattern, but i noticed sometimes it wasn't alternating. What I found
was although my colorization colored the correct items - the sort
wasn't happening until the parent that housed the composite control got
redrawn!!!

I tried a Refresh, an Update, a ResumeLayout, RedrawItems, etc. Nothing
got this to work with the listview. I did code around it myself with a
sortedList, but I find it odd that when I call ListView.Sort it just
seems to queue up the sort for the next paint operation.

Am I mistaken? Does anyone know how this really works?
