ErrorProvider Class
Provides a user interface for indicating that a control on a form has an error associated with it.
Usage
An ErrorProvider is not a visual control on a Form, rather a component of the Form providing a "service". An ErrorProvider is used to display an icon beside a control to indicate the control has an error. When a user hovers over the icon, a Tool Tip appears showing the error description.
Because an ErrorProvider provides the functionality to the Form, you almost always only require one instance of ErrorProvider per Form.
When you add an ErrorProvider to a Form, you will not visually see an item on the form because it is not a visual component. You will the instance of ErrorProvider listed in the component panel before the form designer.
