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

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

public:
property String^ ValidationGroup {
	String^ get ();
	void set (String^ value);
}

Property Value

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

Use the ValidationGroup property to specify the validation group to validate when a postback event is generated. Only the validation controls in the specified validation group are validated.

The following code example demonstrates using the ValidationGroup and PerformValidation properties to ensure that two TextBox controls have information entered in them before the postback event is generated. The NameTextBox and AgeTextBox controls are part of the PersonalInfoGroup validation group, but the StateTextBox control is not. Therefore, the user does not have to enter any data in the StateTextBox control before the postback event is generated.

Security noteSecurity Note

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
