I have an issue with the Windows Forms PropertyGrid control. I have customized the PropertyGrid control and override only OnPaint function.

protected override void OnPaint(PaintEventArgs pe)
{               
    base.OnPaint(pe); 
} 

In my application I have few more controls (treeview, custom control and few form controls). When I mouseclick on the PropertyGrid control, the paint function in all the controls in the screen are being called continuously and the treeview starts flickering. This happens only in mouseclick event.
