Some times it is useful to know whether a selection was made from code or by an userĀ since the AfterCheck event of a TreeView control is fired after both.
Use the code below to see how the selection was made:
private void tree1_AfterCheck(object sender, TreeViewEventArgs e) { if (e.Action == TreeViewAction.ByKeyboard) { .. } if (e.Action == TreeViewAction.ByMouse) { .. } }
