Telerik RadMenu can trigger the built-in ASP.NET validation controls.
To enable validation, make sure the CausesValidation property of the menu is set to true. (This is the default value.)
The ASP.NET 2.0 environment allows you to divide the validators on the page into groups. In case you want to activate only a certain group of validators, simply set the ValidationGroup property to the name of the desired group. If you leave this property blank, Telerik RadMenu will activate all validators on the page.
