Dear Support,
I would like to remove the dotted lines between nodes.
Can this be done?
Thanks,
Ron.

Asking AGAIN:
So I cannot remove the line that comes like from above the beginning of tree?
What is then the benefit of having the function OnTreeGridQueryDrawOutline ?

The CExtTreeGridWnd::ItemGetRoot() method returns a HTREEITEM handle to the root item which is un-removable. It’s always expanded and it always have a NULL parent item. All the other items can be expanded/collapsed and have non-NULL parent item. So, the outline painting algorithm is exactly the same for any level.

One problem regarding this function:
I would like to know if the line drawing is for the first level items, I don’t see the HTREEITEM of the line being drawn, so I don’t know how it get its parent.
I guess it’s the same question of how to get an HTREEITEM from a row & cell -correct?
