Hello Experts,

I can't figure out what I'm doing wrong.

I have a TreeView with CheckBox mode set to True and with nothing but Parent Nodes. After checking the first node and a few other random ones I want to loop through this TreeView, and Remove all nodes except the one at Index 0.

Here's my code. A slight variation of it does work to set the Node-Checkbox-Values to False but not to Remove the same.


For Each ctl As TreeNode In TreeView1.Nodes
 
                    If ctl.Index <> 0 And ctl.Checked = True Then
 
                        ctl.Remove()
 
                    End If
 
                Next
