I'm loading a text file to a RichTextBox control to drag a selection of a
text and drop it into a tree view control. It works except after the drag
and drop operation the RichTextBox scrolls to the top. This is very
inconvenient because after the drag-drop operation the user has to scroll
down to where he was before. Is there anyway to make the RichTextBox stop
jumping to the top after a drag-drop from it?
