The example sets error icon options using the and properties and the and methods. The example creates a that contains a control, a control, and a control, each validating its content, and an for each control. The following code example demonstrates using the class to notify the user of a data entry error. To make your application accessible when using this component, you must provide an additional, accessible feedback mechanism. > The component does not provide built-in support for accessibility clients. When using with data-bound controls, you must specify the, either in the constructor or by setting the property. Typically, you use in association with data-bound controls. When the mouse hovers over the icon, a ToolTip appears showing the error description string. The icon flashes in the manner specified by, at the rate specified by. If an error description string is specified for the control, an icon appears next to the control. presents a simple mechanism for indicating to the end user that a control on a form has an error associated with it. Provides a user interface for indicating that a control on a form has an error associated with it.
