Gets or sets a value indicating whether validation is performed when a button in the ButtonColumn object is clicked.
Assembly: System.Web (in System.Web.dll)
By default, page validation is not performed when a button in the ButtonColumn object is clicked. Page validation determines whether the input controls that are associated with a validation control on the page all pass the validation rules that are specified by the validation control. To perform page validation when a button in the ButtonColumn is clicked, set the property to true.
The value of this property is stored in view state.
