refresh() method

if you're only wanting to refresh certain controls you might want to call this.ControlName.Invalidate() instead..Refresh() forces a complete repaint of all the controls..and also redraws all child controls which may or may not be want you're wanting to do...for example, also make sure you SuspendLayout() before your Refresh or Invalidate, and ResumeLayout() once you're done. If you're using tree controls or such make sure you use .Update() and .EndUpdate() ..hope this helps, if not let me know and I'll take a look at the specific problem you're having.
