)

validationGroup

The validation group name of the controls to validate.

This method is invoked when a user clicks any ASP.NET server control that has the CausesValidation property set to true, which is the default. These include the Button, ImageButton, and LinkButton Web server controls, the HtmlInputButton, HtmlInputImage, and HtmlButton HTML server controls, and controls that can automatically post back to the server such as the TextBox, CheckBox, ListControl, and BulletedList controls.

To disable validation for any button control on the page, set the button control's CausesValidation property to false.

The Validate method validates the specified validation group. After calling the Validate method on a validation group, the IsValid method will return true only if both the specified validation group and the validation group of the control that caused the page to be posted to the server are valid.

The following example demonstrates using the Validate method.

NOTE: This example shows how to use one of the overloaded versions of Validate. For other examples that might be available, see the individual overload topics.
