protected:
 virtual void OnTreeNodeDataBound(System::Web::UI::WebControls::TreeNodeEventArgs ^ e);

protected virtual void OnTreeNodeDataBound(System.Web.UI.WebControls.TreeNodeEventArgs e);

abstract member OnTreeNodeDataBound : System.Web.UI.WebControls.TreeNodeEventArgs -> unit
override this.OnTreeNodeDataBound : System.Web.UI.WebControls.TreeNodeEventArgs -> unit

Protected Overridable Sub OnTreeNodeDataBound (e As TreeNodeEventArgs)

Parameters

e: TreeNodeEventArgs

A TreeNodeEventArgs that contains event data.

Remarks

The TreeNodeDataBound event is raised when a data item is bound to a node in the TreeView control. This allows you to provide an event-handling method that performs a custom routine whenever this event occurs.

Raising an event invokes the event handler through a delegate. For more information about how to handle events, see Handling and Raising Events.

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