Remarks

Use this property to provide a different appearance for alternating items in the Repeater control from what is specified in the ItemTemplate.

Caution

This control can be used to display user input, which might include malicious client script. Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. ASP.NET provides an input request validation feature to block script and HTML in user input. Validation server controls are also provided to assess user input. For more information, see Validation Server Control Syntax.
