Drawing the focus rectangle for a button
-
Hi, I'm trying to draw a focus rectangle on a button, since, when I load a tabpage, if the first control on that page is a button, it doesn't highlight and you can't tell that it has focus. So I stumbled across the
ControlPaint.DrawFocusRectanglecommand and put this in after loading the rest of the page:int x = button2.ClientRectangle.Location.X + 3; int y = button2.ClientRectangle.Location.Y + 3; int w = button2.ClientRectangle.Width - 6; int h = button2.ClientRectangle.Height - 6; Rectangle r = new Rectangle(x,y,w,h); ControlPaint.DrawFocusRectangle(Graphics.FromHwnd(button2.Handle), r, Color.Red, Color.Red);But I get nothing. Then I added a paint event for the button and moved the code there, although instead of sayingGraphics.FromHwnd(button2.Handle), I saide.Graphics. Now it worked, but I'm not able to move away from the button using the up/down arrows. If I throw a messagebox in, after I click the OK button, I can move around without trouble. It seems to have something to do with returning control to the system. Is there anything I can say to give control back to the system? Or am I doing stuff completely wrong? Thanks so much for any thoughts!!!!!! Mel -- modified at 12:18 Monday 1st May, 2006 -

That will select the button and give it a focus rect. Josh
