TreeView.OnInit Method

Raises the Init event.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

protected internal override void OnInit(
	EventArgs e
)

Parameters

e
Type: System.EventArgs

An EventArgs that contains the event data.

The OnInit method is called by the TreeView control to raise the Init event. It is generally used by control developers when extending the TreeView class.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnInit 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 the OnInit method in a derived class, be sure to call the OnInit method for the base class so that registered delegates receive the event.
