Examples

The following code example demonstrates how to use the TreeViewAction enumeration. To run this example, paste the following code in a form that contains a TreeView control named TreeView1. This example requires that TreeView1 is populated with items and the AfterSelect event is connected to the event handler defined in the sample.

private:
   // Handle the After_Select event.
   void TreeView1_AfterSelect( System::Object^ /*sender*/, System::Windows::Forms::TreeViewEventArgs^ e )
   {
      
      // Vary the response depending on which TreeViewAction
      // triggered the event. 
      switch ( (e->Action) )
      {
         case TreeViewAction::ByKeyboard:
            MessageBox::Show( "You like the keyboard!" );
            break;

         case TreeViewAction::ByMouse:
            MessageBox::Show( "You like the mouse!" );
            break;
      }
   }
// Handle the After_Select event.
private void TreeView1_AfterSelect(System.Object sender, 
	System.Windows.Forms.TreeViewEventArgs e)
{

	// Vary the response depending on which TreeViewAction
	// triggered the event. 
	switch((e.Action))
	{
		case TreeViewAction.ByKeyboard:
			MessageBox.Show("You like the keyboard!");
			break;
		case TreeViewAction.ByMouse:
			MessageBox.Show("You like the mouse!");
			break;
	}
}
' Handle the After_Select event.
Private Sub TreeView1_AfterSelect(ByVal sender As System.Object, _
    ByVal e As System.Windows.Forms.TreeViewEventArgs) _
        Handles TreeView1.AfterSelect

    ' Vary the response depending on which TreeViewAction
    ' triggered the event. 
    Select Case (e.Action)
        Case TreeViewAction.ByKeyboard
            MessageBox.Show("You like the keyboard!")
        Case TreeViewAction.ByMouse
            MessageBox.Show("You like the mouse!")
    End Select
End Sub

Remarks

This event does not occur when the node is unselected. To detect whether the selection was cleared, you can test the TreeNode.IsSelected property.
