Disable the textbox when a certain treeview node is selected

hi,

I have a treeview on the left and a textbox on the right devided by a splitter.
What treeview-event should i use when I want to disable the textbox
when a user clicks on a treeview node that has a imageindex 3.

I would say: the afterselect-event but I have allready code there to show text
in the textbox when a treeview node is selected.

        private void tvNotes_AfterSelect(object sender, TreeViewEventArgs e)
        {
            DataRow row = e.Node.Tag as DataRow;
            txtbNotes.Text = row["Data"].ToString();
        }


Who can help me?

Modify your event handler to the following:

private void tvNotes_AfterSelect(object sender, TreeViewEventArgs e)
{
  DataRow row = e.Node.Tag as DataRow;
  txtbNotes.Text = row["Data"].ToString();
  if (e.Node.ImageIndex == 3)
  {
    txtbNotes.Enabled = false;
  }
  else
  {
    txtbNotes.Enabled = true;
  }
}
