true if validation is successful; otherwise, false. If called from the Validating or Validated event handlers, this method will always return false.
Remarks
The Validate method validates the last child control that is not validated and its ancestors up through, but not including, the current container control. This overloaded version always performs validation, regardless of the value of the AutoValidate property of the control's parent. Therefore use it to unconditionally force validation.
