DrawBorder3D query

Hi

In my Explorer look application, i want the panels to have a 3D look, so i
used the following.
private void panel_Paint(object sender, System.Windows.Forms.PaintEventArgs
e)
{
base.OnPaint (e);
Rectangle borderRectangle = this.ClientRectangle;
ControlPaint.DrawBorder3D(e.Graphics, borderRectangle,
Border3DStyle.Etched);
}

This is working but problem is, when the spliter window is resized the
rectangle is drawn to the new size without cleaning the old rectangle.
After resizing the panel has 2 rectangles.
How can i clear the old border before drawing the new one ?

Thanks

Matt

Hi Matt,

Thanks for your post.

Based on my knowledge, normally, this will not happen at all. Because when
the splitter control is moved to resize the window, the original part will
become invalid, and will be refreshed with the new drawing. So there should
not be this problem.

Can you provide a little sample project for us to reproduce out your
problem? Then we can understand it much better. Thanks

You can first fill the entire panel with the "windows" color and then draw
the border.

You can clear the control using 'e.Graphics.Clear(this.BackColor)'.
Afterwards draw the new border.

Just a thought....

Create a custom Panel class that derives from the
System.Windows.Forms.Panel

and in the constructor for your custom Panel add this line:

this.SetStyle( ControlStyles.ResizeRedraw, true );


Then make sure to update your code to use the CustomPanel rather than
the standard System.Windows.Forms.Panel.

To make sure the styles get updated I'd call 'this.UpdateStyles()' here too.
