HtmlInputImage::OnPreRender Method

Raises the PreRender event.

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

protected public:
virtual void OnPreRender(
	EventArgs^ e
) override

Parameters

e
Type: System::EventArgs
An EventArgs that contains the event data.

The OnPreRender method is called just prior to rendering the HtmlInputImage control. The OnPreRender method is used primarily by control developers extending the functionality of the HtmlInputImage control.

Notes to Inheritors

When overriding the OnPreRender method in a derived class, be sure to call the base class's OnPreRender method so that registered delegates receive the PreRender event.

The following code example demonstrates how to override the OnPreRender method so that it always displays a custom HtmlInputImage server control with no border.
