Attributes

Examples

The following code example demonstrates how to use the ShowMessageBox and ShowSummary properties to specify that the validation summary is displayed in both a message box and on the Web page.

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.
