Public ref class Form1: public System::Windows::Forms::Form The SetError method is called with or without appropriate error text during a control's Validated event, depending upon the content in the control. The example sets error icon options using the BlinkRate and BlinkStyle properties and the SetIconAlignment and SetIconPadding methods. 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 following code example demonstrates using the ErrorProvider class to notify the user of a data entry error. System.Object System.MarshalByRefObject (, System.IDisposable) ErrorProvider( assigned value is not one of the ErrorBlinkStyle values. public class ErrorProvider : : Hierarchy To clear the error condition, call SetError() for the control with an empty string (''). The alternative is to use the SetError() method, which allows you to set specific error text for any control.

The simplest is to set the DataSource property to refer to a, and you will automatically get errors displayed for any rows that have a column error (either set by the framework, or with the () method). There are two principle modes of operation. (See ErrorBlinkStyle for more information about this). The icon can also be made to blink using the BlinkRate and BlinkStyle properties. The position at which an icon should appear is set using the Get / SetIconAlignment() and Get / SetIconPadding() methods. You can also set a specific Icon if the default red circle with a white exclamation is not to your taste or culture. This happens automatically if the ErrorProvider is dropped onto a designer surface. When the user hovers the mouse over the icon, a ToolTip appears containing some text descriptive of the error.įirst, you must set the ContainerControl property to the container for the controls that need validation. This component allows you to display a small Icon next to a Control to indicate that there is something wrong with the user input.
