Hi Paul R.,
This is a known issue with the custom GDI
painting and AutoScroll
controls which is the case with RadControls for WinForms. The blue lines you are seeing are caused by the RadPanel
's border so removing the border can fix the issue:
radPanel1.PanelElement.PanelBorder.Visibility = ElementVisibility.Collapsed;
If you do not want to remove the border, you can use the RadScrollablePanel
control. Just set the AutoScroll
property to true
and when any control on it exceeds its bound, the scrollbars will be displayed. In addition to this, you will also get a fully themeable scrollbars.
I hope this information was useful. If you have any further questions, do not hesitate to ask.
