TreeView.OnAfterExpand(TreeViewEventArgs) Method

Definition

Raises the AfterExpand event.

protected:
 virtual void OnAfterExpand(System::Windows::Forms::TreeViewEventArgs ^ e);
protected virtual void OnAfterExpand (System.Windows.Forms.TreeViewEventArgs e);
abstract member OnAfterExpand : System.Windows.Forms.TreeViewEventArgs -> unit
override this.OnAfterExpand : System.Windows.Forms.TreeViewEventArgs -> unit
Protected Overridable Sub OnAfterExpand (e As TreeViewEventArgs)

Parameters

e
TreeViewEventArgs

A TreeViewEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnAfterExpand method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnAfterExpand(TreeViewEventArgs) in a derived class, be sure to call the base class's OnAfterExpand(TreeViewEventArgs) method so that registered delegates receive the event.
