Hallo Support-Team! Is there a way to remove the first line like it is in visual studio class view.? I think it is also in the standard control class CTreeCtrl, but I am not sure. 
Regards

At present, this task requires overriding visrtual methods of the CExtTreeGridWnd class. CExtTreeGridWnd::OnTreeGridQueryColumnOutline() determines which column should display a tree outline. It’s possible to display a tree outline in more than one column or hide it at all. CExtTreeGridWnd::OnGbwAdjustRects() reserves some space for tree outline. Finally CExtTreeGridWnd::OnGbwPaintCell() draws a tree outline and this is the method you need to implement if you want to change outline lines.

I didn’t understand the relationship between CExtTreeCtrl and CExtTreeGridWnd.  I have had a look into a the funktion CExtTreeCtrl::OnPaintTreeItemLines and it seems that I have overriding this funktion. Is this right?

We are sorry but there is no relationship between the CExtTreeGridWnd and CExtTreeCtrl classes. But the CExtTreeCtrl control is also completely custom painting and it’s also possible to repaint its outline. You should override the CExtTreeCtrl::OnPaintTreeItemLines() method for that.
