Paint Events

[Barguast]

Urgh... I still can't get this right. I tried the suggested events for calling the DrawOnTheControl function, but it still won't paint it when the control first appears. I tried instead to draw the borders when the form is initialised or resize, for example:

private void frmMain_Load(object sender, System.EventArgs e)
{
     drawBorder (textBox1, Color.Blue);
}

private void drawBorder (Control ctrl, Color colour)
{
     Graphics g = ctrl.CreateGraphics ();
     Pen p = new Pen (colour, 2);
	
     g.DrawRectangle (p,
          ctrl.ClientRectangle.Left, ctrl.ClientRectangle.Top,
          ctrl.ClientRectangle.Width, ctrl.ClientSize.Height);
            	
     g.Flush ();
     g.Dispose ();
}

It works ok with the resize event (although you can still see 'trails' of the original black colour), but the Load function doesn't work at all - I'm guessing this is because the control hasn't been loaded yet.

Is there not a better way to do this?

Also, while I've got the code posted, how can I pass the control in by reference? I've tried using 'ref' but it complains about me passing a TextBox rather a Control.

Thanks with your help so far, though
