ButtonColumn.CausesValidation Property

Gets or sets a value indicating whether validation is performed when a button in the ButtonColumn object is clicked.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public virtual bool CausesValidation { get; set; }

Property Value

Type: System.Boolean
true if validation is performed when a button in the ButtonColumn is clicked; otherwise, false. The default is false.

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 CausesValidation property to true.

When the value of the CausesValidation property is true, you can also use the ValidationGroup property to specify the name of the validation group for which the ButtonColumn causes validation.

The value of this property is stored in view state.
