HtmlInputFile::OnPreRender Method

Raises the PreRender event for the HtmlInputFile control.

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 event data.

If no encoding is specified for the Web page's HtmlForm control, the Enctype property is set to "multipart/form-data".

The following code example demonstrates how to override the OnPreRender method so that a Title attribute is always added to each custom HtmlInputFile control. For this example to work properly, you need to create a directory called Temp on your computer's drive C.
