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 System.Web.UI.WebControls.Button, System.Web.UI.WebControls.ImageButton, and System.Web.UI.WebControls.LinkButton Web server controls, the System.Web.UI.HtmlControls.HtmlInputButton, System.Web.UI.HtmlControls.HtmlInputImage, and System.Web.UI.HtmlControls.HtmlButton HTML server controls, and controls that can automatically post back to the server such as the System.Web.UI.WebControls.TextBox, System.Web.UI.WebControls.CheckBox, System.Web.UI.WebControls.ListControl, and System.Web.UI.WebControls.BulletedList controls.

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

The Page.Validate(string) method validates the specified validation group. After calling the Page.Validate(string) method on a validation group, the Page.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.
