I've searched the forum for a possible solution; there were several questions asked, but none answered with any solution . When I click on a node within the treeview, I would like the focus to change to a RichTextBox and have the mouse caret flash; this does not happen. I use VB.NET 2003. I've tried things such as: if textbox.canfocus then textbox.focus. The nodes are loaded from a node collection. Has anyone found a solution to this problem?
