Mobile controls, such as the Command, can override this method to determine whether this is a control used for form submission.
Other controls can be extended by providing logic to programmatically determine whether or not they must be submit controls, for example, by checking for specific properties.
A control is considered to be a form-submit control only if it implements IPostBackEventHandler method to capture the postback event. Otherwise, it is not registered for the default event handler, even if the method returns true.
