Property Value

By default, page validation is performed when a tab is selected. Page validation determines whether the input controls associated with a validation control on the page all pass the validation rules specified by the validation control. You can specify or determine whether validation is performed on both the client and the server when a tab is clicked by using the CausesValidation property. To prevent validation from being performed, set the CausesValidation property to false.
