CommandField::CausesValidation Property

Gets or sets a value indicating whether validation is performed when the user clicks a button in a CommandField field.

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

virtual property bool CausesValidation {
	bool get () override;
	void set (bool value) override;

Property Value

Type: System::Boolean
true to perform validation when the user clicks a button in a CommandField field; otherwise, false. The default is true.

Use the CausesValidation property to specify whether validation is performed when a button in a CommandField field is clicked. When this property is set to true, by default all validation controls on the page are validated. To limit validation to only a certain group of validation controls, create a validation group and then set the ValidationGroup property to the validation group's name. For more information on validation groups, see BaseValidator::ValidationGroup.

The following code example demonstrates how to use the CausesValidation property to prevent validation from occurring when a button in a CommandField field is clicked.

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.
