TreeView::AfterSelect Event
Occurs after the tree node is selected.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
This event does not occur when the node is unselected. To detect whether the selection was cleared, you can test the TreeNode::IsSelected property.
For more information about handling events, see Consuming Events.
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; } }
The following class inherits from the Button class and overrides the OnMouseHover and OnMouseMove methods to give the button some special behavior. To use this example create a new form and copy paste this class in the same file, after the form class. Add a button of type FunButton, defined in the code example, to the form.
