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

Member nameDescription
AlwaysBlinkAlways blink when the error icon is first displayed, or when a error description string is set for the control and the error icon is already displayed.
BlinkIfDifferentErrorBlinks when the icon is already displayed and a new error string is set for the control.
NeverBlinkNever blink the error icon.

This enumeration is used by ErrorProvider.

The following example demonstrates using the ErrorProvider class to notify the user of a data entry error. The example creates a Form that contains a TextBox control, a NumericUpDown control, and a ComboBox control, each validating its content, and an ErrorProvider for each control. The example sets error icon options using the BlinkRate and BlinkStyle properties and the SetIconAlignment and SetIconPadding methods. The SetError method is called with or without appropriate error text during a control's Validated event, depending upon the content in the control.
