GridView.OnPreRender(EventArgs) Method

Definition

Raises the PreRender event.

protected public:
 override void OnPreRender(EventArgs ^ e);
protected internal override void OnPreRender (EventArgs e);
override this.OnPreRender : EventArgs -> unit
Protected Friend Overrides Sub OnPreRender (e As EventArgs)

Parameters

e
EventArgs

An EventArgs that contains the event data.

Remarks

This method notifies the server control to perform any necessary pre-rendering steps prior to saving view state and rendering content.

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

The OnPreRender 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 OnPreRender(EventArgs) in a derived class, be sure to call the base class's OnPreRender(EventArgs) method so that registered delegates receive the event.
