• Hensen Exiting from a UserControl Prematurely

  I have a UserControl that contains several textboxes. Under certain conditions I need to exit the Control (ie move to the next control on the parent form after the User Control) from a text box that is not the last one in tab order on the control. In the Validation Event of the text box I have tried changing focus to the last textbox in the control and executing Me.ProcessTabKey(True). The focus remains with the last text box. I have tried Me.ProcessDialogKey(Keys.Tab), but that seems to go off into loop. I could throw an event, but that would require that the parent form always process it. What is the secret of exiting the UserControl programatically either forward or backward Any help would be appreciated. ...Show All

• Ceres629 Column Sort

  Hi, i'm new with datagrid and i'm wondering how can i make the alphabetical sort of the column to work, does .Net already hasve that functionality I don't know if this is important but the datagrid was filled with data from an array. tkns If you are using the .net Framework 2.0 I would extend the BindingList to support sorting. C# example . VB 2005 example . Put you data in the bindinglist and bind to that.

• AdrianB Complex user control not responding to click events

  Hi all, I'm wondering whether any of you people can help me out with this problem that I have with a user control that I have been trying to get working. The first part of the user control is a flat circular button ( called SampleButton) that toggles colour when clicked. This control has an OnClick method as follows protected override void OnClick(EventArgs e) { base.OnClick(e); (code to change colour and call invalidate....) } Then, from this I am creating a matrix of these buttons in another user control that inherits from SampleButton (which in turn inherits from UserControl), e.g. a 3 x 3 matrix, like so: O O O O O O O O O I do this using a couple of for loops (the number of Sampl ...Show All

What you are seeing is the BindingNavigator is trying to set the Add or Delete button state based on the current state of the list - and this is happening after you've set the state, so if the bindingsource is allow to add o ...Show All

• Nicolas Barry SuspendLayout ignored for mdi forms?

  Hi, I have a form with three dozen controls in a layout. When I ShowDialog this form it's almost instantaneous, but if I add it as a tabbed MDI form, it takes three seconds to draw the controls. We can see a wave of textboxes appear from top to bottom then another wave of labels from bottom to top. Has anyone seen this behavior before Is there any fix Thanks, Charles "Tabbed MDI form", not sure what that is. If you are using a TabControl, are you calling the TabControl's SuspendLayout() method I'm using this control: http://www.codeproject.com/vb/net/MDITabControl.asp and it works great in all cases except one where the layout is very slow.
