InsertItemPosition

One of the InsertItemPosition values. The default is None, which indicates that the InsertItemTemplate content will not be rendered by the ListView control.

Examples

Important

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
