TreeView Node BackColor on losing fous

Question

0.00/5 (No votes)

See more:

When I click on a node in the TreeView it of course becomes highlighted. But when I switch the focus to a button, or a textbox or anything it is no longer highlighted. I'm pretty sure it's still "selected" but not visually. Is there a way to make it stay visually selected?

Thanks!

What you basically need to do is color the background of the selected node when the control loses focus.
You could try the following:

VB

Private Sub TreeView1_LostFocus(sender As Object, e As System.EventArgs) Handles TreeView1.LostFocus
    ' When your TreeView loses focus get the currently selected node and
    ' change the backcolor of the node to something that indicates inactivity.
    TreeView1.SelectedNode.BackColor = SystemColors.InactiveCaption
End Sub

Private Sub TreeView1_GotFocus(sender As Object, e As System.EventArgs) Handles TreeView1.GotFocus
    ' When the TreeView receives focus again the last selected nodes backcolor needs to be reset.
    TreeView1.SelectedNode.BackColor = Nothing 
End Sub

Hope it helps :)

Solution 2

When you lose focus from the app it doesn't seem to trigger the treeview1_lostFocus.

I noticed when taking a screen shot with a third party tool.
