When a control is embedded in a user control, the Validate event does not fire when you use the accelerator, and the system does not perform checking operations.
The Validate event occurs before the focus shifts to a control that has its CausesValidation property set to True. If a user control is created with a constituent control (such as a text box), and then the first control is put on a form, the Validate event of the text box fires, and then the Validate event of the user control fires when a user uses the TAB key or a click of the mouse to remove focus from the text box to a control that is directly on the form (that is, the control is not part of the user control). However, the Validate event of the text box does not fire if a user removes focus by using an accelerator key to select an external control.

As an example, assume that a text box is embedded in a user control, and then the user control is put on a Microsoft Visual Basic form. A Button control that is labeled OK is then added to the form outside the user control, and then the ALT+O accelerator is assigned to the Button control. If focus is then set to the text box, the Validate event of the text box does not fire if the user presses ALT+O to select OK.
