    - Problem with databinding and RowChanging event I created a method to handle the RowChanging event to validate some data in a databound form. I am using BindingManagerBase.EndCurrentEdit to trigger the RowChanging event. If the data cannot be validated then an exception is raised in the RowChanging event and catched after the call to EndCurrentEdit. The problem I am having is that after calling EndCurrentEdit and raising the exception inside the RowChanging handler, the values in the controls in the form that are not modified again are not fetched again. For example... I have a form with 2 edit boxes which are data bound. Edit1 and Edit2. The original values for each are "mary" and "smith" respectively. If I modify Edit1 to contain "John" and call EndCurrentEdit, the RowChanging event is fired. If I check the Current version of the column it contains "Mary" and the proposed version contains "John". If I raise an exception within the event handler then the data is not saved to the dataset as expected. At this point I still have the edit boxes containing "John" and "Smith"... I am not calling CancelCurrentEdit because I don't want to roll back to the current values... I am simply letting the user know that the data entered is incorrect. If at this point I edit the Edit2 to "Roberts" and call the EndCurrentEdit method, the RowChanging event is fired... but if I check the proposed version of the Edit1 bound column, it contains the Current value "Mary" and NOT the value currently in Edit1. If the user does not edit the Edit1 control directly, the value is not reflected when EndCurrentEdit is called. Thanks, Jeronimo Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82147

    - Webbrowser control + MDI + Disable ctrl-n I am using the Webbrowser control in a MDI application. The Webbrowser control is in a User Control which is loaded into a form. I have implemented IDocHostUIHandler for the User Control and have set the SetUIHandler to the User Control (this). I have also disabled ctrl-n by implementing TranslateAccelerator.The problem is, as the mdi form is loaded initially, I can do ctrl-n and it will popup a new IE browser. Once I click anywhere on the browser, then disables ctrl-n. Any ideas? Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82145

    - Hosting .NET Windows forms UserControl in IE Hello, I need to host .NET Windows forms UserControl in Internet Explorer. I do it by including <OBJECT> tag in my aspx page: <OBJECT id="mycontrol1" classid="MyControl.dll#MyControlNamespace.MyControl" width=800 height=300 style="font-size:12;" VIEWASTEXT> </OBJECT> everything works fine, MyControl.dll gets downloaded into the download cache and IE displays the control. The problem however is the fact that the browser needs to download MyControl.dll file. Our clients will block downloads of .DLL and .EXE files. I would like to use CAB file instead, for example, I tried codebase attribute as in the following: <OBJECT id="mycontrol1" codebase="MyControl.cab" classid="MyControl.dll#MyControlNamespace.MyControl" width=800 height=300 style="font-size:12;" VIEWASTEXT> </OBJECT> but it does not work. Is there a way of making IE to download a CAB file, just as it does for an ActiveX components, and extract contents into the download cache, so that no DLL file needs to be downloaded? Thank you, Slava. Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82143

    - Getting ToolTip from a control.. In a control it is usefull in some cases to know if it is included on a toolTip, HelpProvider etc. How do you access this information?

Anyone else have a better way of doing this??? /// <summary> /// Method: This gets the ContainerControl and then looks for an /// IContainer field named "components" /// used by the windows designer.

    - Winform scrollbars and Maximize I have an MDI application that has 4 child windows. When my application opens, it initialially opens all of the forms un-maximized. When I then choose to maximize all of the windows and then in my code switch the app to one particular window, that one window does not appear maximized. Instead, I have to double-click on the title bar and then in the control box I see the option to maximize. Otherwise the control box shows what appears to have 'restore' capability. Not sure if this explaination makes sense. I have the autoscroll set to true on the window because the controls on the window go down farther than the height of the window. Is there something to do with the autoscroll that could be causing this behaviour? Thanks. STom Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82133

    - Inherited User Control not showing in designer I have a user control that inherits from another user control. The base user control works fine in the designer, I can see all of the controls, etc... However when I open the derived control in the designer, all I see is a grey square with no controls. I have tried attaching to the IDE with another instance's debugger, but no exceptions are being thrown when the control is open. Here is how the constructors are setup: Base Control: public class MyBase : System.Windows.Forms.UserControl { [Browsable(false)] protected AnotherObject _oObject; [Browsable(false)] public AnotherObject oObject { get{ return _oObject; } set{ _oObject= value; } } public MyBase() { _oObject= new AnotherObject (); } public MyBase (AnotherObject oObject) { InitializeComponent(); _oObject= oObject; } } Derived Control: public class MyDerived: MyBase { public MyDerived(AnotherObject oObject) : base(oObject) { InitializeComponent(); } public MyDerived() : base() { } } Please help!

    - Prompt if changes for databinding Hi, I am writting a data navigator where if the user edits a form and tries to move to a different record on the dataset without saving the current record, he is prompted to save it before the BindingManagerBase position is changed. I created a navigator class that includes a dirtyRow flag to check when the user selects to move to a different record. I am trying to keep track of changes by adding events to TextChanged on the edit boxes of my form. If a textbox changes then the dirtyRow flag is set. However I am encountering some problems since the TextChanged event is also fired when text is changed due to the databinding for the control. I added an event for PositionChanged on the BindingManagerBase that sets dirtyRow to false and in general this works because when the position is changed, the databinding sets the dirtyRow to true on the TextChanged event but the PositionChanged event is called after the TextChanged event and therefore the newly visited row is not considered dirty until the user changes the text on the edit boxes. However this does not work the first time the form is created because in that particular case, the TextChanged event from the databinding is called AFTER the PositionChanged event. My question... 1- Is there any way of knowing IF the EndCurrentEdit will actually modify the underlying dataset? I noticed that RowState for a row changes to Modified after EndCurrentEdit if there are changes. I want to prompt the user to keep or save changes only if changes exist. 2- Is there an event that I can use to know that databinding for the form on the current position has completed so I can set the dirtyRow flag to false?

    - Tabbing Into a Custom DatagridColumnStyle at ColIndex(0) This is a duplicate post. I wanted to be sure to post in the managed group to take advantage of my subscription. Sorry for the initial mispost. JT Hello, I am literally banging my head against the wall trying to figure out how to use the tab key to move from the last column in a datagrid row to the first column in the next row when that first column is a Custom DataGridColumnStyle (in this case, as combobox). I have seen George Shepherd's suggestion on subclassing the embedded control, and have tried three different ways of doing this, as shown below. NONE of them work. I think I know why... After having tabbed through my datagrid, when I then look at the trace for "Debug.WriteLine(keyData.ToString)", I see Tab for every move I made from one column to the next ON THE SAME ROW. But when my tab key cause a new row to become current, my debug trace shows nothing at all. Question is, how to solve this problem. Can anyone enlighten me as to exactly how the datagrid moves to a new row in response to the tab key? Maybe if I can understand that, I can achieve what I am trying to achieve. Thanks.

    - WindowEnumerator My application has regular document windows and floating windows above them. I want to iterate through all windows in z-order. I would have thought this capability would be built-in to the .net framework, but everything I can find on the archives says no - you need to use GetWindow(), thus: [DllImport("user32", EntryPoint="GetWindow")] private static extern int GetWindow(int hwnd, int wFlag); And the most logical thing seems to me to be to create a class that implements the IEnumerator interface. I suspect I need an additional external function - maybe GetTopWindow? to get a starting point; call that in .Reset() and GetWindow() in .MoveNext(). Am I on the right track? Can anyone provide examples of how to call these functions, eg what arguments to pass to them, how to coerce their result types into System.Windows.Forms, how to tell when I've reached the end?

    - updating forms? my program draws a form and when you click the start button another form is drawn with a progress bar as it runs through a function. my issue is that when you click on another progrem then try to go back to the progress bar form it doesn't redraw itself. i tried using a: if(num%100==0) this.Update(); where num is just to count each time it runs through the loop. the program still works and finishes, but i can't seem to get the progress bar form to redraw itself. the this.Refresh() and Update() did not work either. any suggestions? btw...it's for an installer, so as it's uploading the database the progress bar goes, all of it works fine, just need the form to redraw itself if it loses focus.

    - Validation problem I have a form that contains a TabControl. A tabpage on the control contains a TextBox that is bound to a field in a DataTable. The textbox is readonly. When the user clicks an Edit button, the field becomes editable. The user then has the choice of clicking the Cancel button, to discard any changes, or Update to finish the editing mode. Because the field cannot be NULL, when the user clicks Update the field should be validated. The textbox and the update button both have CausesValidation set to True, while the cancel button does not.

    - Question re Migration of VB6 App to .NET Our company develops and markets a client/server application which is written in VB6 as a rich Win32 Client/Server application. For a variety of technological reasons we are looking to migrate toward the .NET environment. However, a number of business factors make it impractical to accomplish this through an abrupt termination of the VB6 product and complete rewrite. Instead, we are looking to perform new development in .NET and slowly over time migrate existing code to .NET. At this time, we are looking to add a brand new module to our product. Obviously, the new module has some connection to the rest of the application in general. Be that as it may, it is sufficiently encapsulated unto itself that we are contemplating developing this new module in .NET. I'm interested in any advice which you can offer about how we might 'plug in' a module written in .NET into our VB6 application, specifically at the UI layer. We must provide the user with a seamless UI interface to our application, regardless of whether the user is interacting with a VB6 Form or with a .NET WinForm. Thanks very much for any advice which you can provide. - Joe Geretz - Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82071

    - Load event in user control Hi Gurus. I'm doing my first steps in the Winforms realm (I dealt mainly with ASP.NET until now), and I've stumbled across issue I really cannot solve and that seems extremely stupid to even ask about, so please forgive me... I need to execute some logic in the Load event of the control. Problem is - I can't find that event for user controls! This logic cannot be executed in the control's constructor, because its properties are not set yet. I don't want to modify the InitializeComponent method code, as I understand it is strongly un-recommened. In ASP.NET, there is a Load event for every control, which enables me to do just that. What is its equivalent in Winforms controls? Thanks! Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82062

    - OnStartTask in UIP v 2.0 Hi, I'm using UIPAB v 2.0 in a Windows application. Following the UIP documentation I'm trying to "nest" two tasks. As I need to pass data between those two tasks, I;m using the OnStartTask method. This is what the documentation say about nesting tasks, using that method: "When the Add New Shipping Address process is ready to return, retrieve the TaskId for the Purchase Product process, which is stored in the current task's state, and invoke the OnStartTask method, passing the name of the navigator, the new address, and the original TaskId. If the task state for the specified task is found, the current view for that task is displayed." The problem is that the OnStartTask method requires an Itask implementation as its third argument and not plainly the TaskId. Should I implement the ITask just for the sake of resuming a suspended task? Thanks, Gwenda Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82061

For some sick reason this Form2.PanelTop always overlaps the central panel. It doesn't move the central panel down, making my first edit box INVISIBLE (as in not longer able to see it.)

I found the following code snipped for VB6 elsewhere on the forums--it's close: Dim IE As Object Set IE = CreateObject("InternetExplorer.Application") IE.Visible = True IE.navigate "http://www.kbb.com" Do Until IE.readyState = 4 DoEvents Loop IE.Document.emailsignup.email.Value = "MYEMAIL" But... * I need to do with a .NET Windows app, not VB6 * The IE window will already be open (the user must sign on and display it first--code cann't do that) * Once items on the IE form have been filled, the IE Window needs to be brought in focus so the user can fill in other form elements before submitting. Ideas? THANKS! Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82050

    - Help on design decision with Tree structure data I have some data organized in a tree structure saved in an XML file and I want to display it in a TreeView control (the XtraTreeview of DevExpress). Each data item I would like to store in a class so that I can attach to it some logic (for example to each data is associated an Execute method). I wonder what is the best solution: subclass the TreeView Node and extend it adding all the logic I need or create a completely detached tree structure that contains my data and then link it somehow to the TreeNode component (probably this way is nicer since I don't match and mix business logic with the interface). One thing to notice is that the data will change (the user can modify it) so I'll have to take care of updating the data structure. Thanks a lot for any suggestion.

    - Docking Toolbars In Windows Forms I have a main Toolbar and I also have a control that contains a toolbar. Is there a way of docking the control's toolbar besides the main toolbar? Or just docking the control's toolbar in the main Window's form (not just docking it within the control but outside of it in the main form)? Thanks in advance, Tom.

    - datagrid wrapped textbox column Hi, I have a database table with long text fields. I use datagrid to display the data. For long text fields I build custom column which inherits from DataGridTextBoxColumn so I can wrap text in the datagrid cell. Custom TextBoxColumn is able to determine the column height. I overrided GetMinimumHeight and Paint methods. To edit row data I launch dialog window. My problem is : when I finished with dialog window text fields will be changed and I want datagrid/my custom column recalculate the height. But datagrid doesn't ask my custom column to do this (call GetMinimumHeight on custom column). Unless I manually resort datagrid - click on column header. Is there any solution to force datagrid to call GetMinimumHeight in custom column Thanks, Rynad Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82045

    - Improving Performance I have a table called tblOrg in a SQL Server 2000 database. It has PK = Org_ID and a field called ParentOrg_ID so an Organization can have 0, 1 or many children but only one parent. I have a recursive function that builds a tree view of this and populates a tree control with Org_ID as the key and OrgName as the Text. Everything works great and performance is great as long as the data base and the application are on the same machine. But performance is unacceptable on a remote machine connected via a LAN. This is to be expected because the application is using sqlcommands to build the tree in the recursive function. Thus, the same sqlcommand is executed once for each organization. Obviously to get the most update version of the data you have build it from the database. But what other ways are there, that once built, one can reuse it rather that rebuild the tree? For example, the user selects OrgType from a dropdown (College, High School, Middle School) which populates the tree control with organization of that type, he then can select the Organization and populate the form with the details of the selected organization. When changing the OrgType, the control is completely rebuilt via the recurisive function which goes to the database. Instead, it would be nice to persist the previously clicked OrgTypes in memory so that the tree control is populated from memory if that OrgType is reselected. Since this tree control is used in other places in the application, it might be better to populate a dataset in memory so that all projects within the application can reference and populate the tree control that way or, better yet, all instances of the application can use it. For example, a user A opens his application which causes the Tree to be built. But user B opens his application but the application has access to the already populated tree because of User Aâ??s work (This organization structure does not change often). How can I do this? Any VB or C# code examples would be nice? WR Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82044

    - Merging Toolbars Hi, I have my main Windows Forms Application and a control that contains a context menu and a toolbar. Now I was able to merge the control's context menu with the application's main menu no problem by using the MergeMenu functions. I cannot find anything similar for merging toolbars. Is there a way for merging toolbars so that the control's buttons will be incorporated into the main application's toolbar and yet their functionality will be accessed from the control (just like when the menus are merged)? Thanks for your help in advance, Tom. Tag: Scrolling in DataGridView in Visual Studio 2005 Tag: 82040

    - scroll box width once more The scroll box of an independent scrollbar is affected by the difference between Maximum and Minimum like so (approximately): percentage of scrollbar occupied by scrollbox = 1000 / (Maximum - Minimum). Does anyone have the exact rules that apply here, i.e. how is the width of the scrollbox exactly determined? T.I.A. P.S.
