ButtonFieldBase::CausesValidation Property
Gets or sets a value indicating whether validation is performed when a button in a ButtonFieldBase object is clicked.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System::Booleantrue to perform validation when a button in a ButtonFieldBase is clicked; otherwise, false. The default is false.
Validation groups allow you to assign validation controls on a page to a specific category. Each validation group can be validated independently of other validation groups on the page. Use the ValidationGroup property to specify the name of the validation group for which the ButtonFieldBase object causes validation when it posts back to the server.
The ValidationGroup property has an effect only when the value of the CausesValidation property is set to true. When you specify a value for the ValidationGroup property, only the validation controls that are part of the specified group are validated when the ButtonFieldBase posts back to the server. If you do not specify a value for the ValidationGroup property and the CausesValidation property is set to true, all validation controls on the page that are not assigned to a validation group are validated when the ButtonFieldBase posts back to the server.
The value of this property is stored in view state.
The following code example demonstrates how to use the CausesValidation property to perform validation when the button is clicked in the ButtonField object of a GridView control.
