ButtonColumn.ValidationGroup Property

Gets or sets the group of validation controls for which the ButtonColumn object causes validation when it posts back to the server.

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

public virtual string ValidationGroup { get; set; }

Property Value

Type: System.String
The group of validation controls for which the ButtonColumn object causes validation when it posts back to the server. The default is an empty string ("").

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 ButtonColumn 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 ButtonColumn 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 ButtonColumn posts back to the server.

The value of this property is stored in view state.
