CausesValidation Property

ListControl.CausesValidation Property

Gets or sets a value indicating whether validation is performed when a control that is derived from the ListControl class is clicked.

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

[ThemeableAttribute(false)]
public virtual bool CausesValidation { get; set; }
<asp:ListControl CausesValidation="True|False" />

Property Value

Type: System.Boolean
true if validation is performed when the ListControl control is clicked; otherwise, false. The default is false.

Use the CausesValidation property to determine whether validation is performed when a ListControl control 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.

By default, clicking a control that is derived from the ListControl class does not cause page validation. To perform page validation when the control that is derived from the ListControl class is clicked, set the CausesValidation property to true.

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

The value of this property is stored in view state.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins.
