Adding combo button on a textbox

Adding combo button on a textbox

• DavidAtPgMensys

  Try creating a UserControl. That's what they're for :)

  normaly this works:

  override the onpaint of the textbox and put this code in

  ControlPaint.DrawComboButton(e.Graphics, buttonRectangle, ButtonState.Normal)

   Buttonretangle is the retangle specifying the button location and size

  not sure about textboxes, I think there are drawn by the os instead of the framework.

  if that's the case then draw on it's hosting control

   

  Good luck

  Yeah, it sucks

  On all kind of controls you can override the paint with the exception of textbox(and a few others)

  I had a simular 'problem' a few months ago see here: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=109945&SiteID=1

  wat you can do in this case is add a button to the textbox control cellection and dock it to the side of the textbox.

   

  Good luck

  The solution of adding a Button control on runtime, and dock it to the TextBox control is a good idea, and I think you should go for that.
  
  As for TextBox control's paint issue, yes, regular textbox doesn't trigger the OnPaint method, but it does process WM_PAINT, WM_NCPAINT and other paint related messages, and you can get this via the WndProc override. For some example on how to do this, see this thread: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=170500&SiteID=1

  I tryed overriding OnPaint method, but it doesn't work.

  I'd like to handle painting into the control like MFC.

  Any hints
