ContainerControl.Validate Method

Verifies the value of the control losing focus by causing the Validating and Validated events to occur, in that order.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public bool Validate()

Return Value

Type: System.Boolean
true if validation is successful; otherwise, false. If called from the Validating or Validated event handlers, this method will always return false.

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.
