So, the code is anycodings_label not optimized. As noticeable as the ErrorProvider user interface is (at least compared with the status. Return Regex.IsMatch(dNumber, not forget to add references (F4) to: anycodings_label Īnd then add anycodings_label the following namespaces: System.Drawing NET development series) Chris Sells, Michael Weinhardt-Windows.

ValidatedControls.Add(TxtDateiName, new ErrorProvider(this)) If you've got LinqPad, you can use this anycodings_label script to check how it works: void Main() When you move cursor over icon, you'll anycodings_label see error details: Msdn errorprovider windows#Here is MSDN example: How to: Display anycodings_label Error Icons for Form Validation with the anycodings_label Windows Forms ErrorProvider Component ErrorProvider permite una forma sencilla de mandar un mensaje de error al usuario directamente en la interfaz grfica.Suscribete, nuevos videos cada semana. The key method of the ErrorProvider component is the SetError method, which specifies the error message string and where the error icon should appear.As i mentioned in the comment to the anycodings_label question, i'd use ErrorProvider instead anycodings_label of spending time to write code to anycodings_label manipulate controls on the form. When the DataSource property is set, the ErrorProvider component can display error messages for a dataset. The Icon property can be set to a custom error icon instead of the default. When the component is added in the designer, the ContainerControl property is set to the containing form if you add the control in code, you must set it yourself. Error providers, coupled with disabling a Save button, for instance, can provide a block to continuing as well as information as to why, all without annoying pop-ups. I try to limit pop-up boxes, as they can be annoying to the user. When using ErrorProvider component with data-bound controls, the ContainerControl property must be set to the appropriate container (usually the Windows Form) in order for the component to display an error icon on the form. In fact, for in-place validation such as you are doing, I tend to prefer them. The ErrorProvider component's key properties are DataSource, ContainerControl, and Icon. The ErrorProvider component displays an error icon ( ) next to the relevant control, such as a text box when the user positions the mouse pointer over the error icon, a ToolTip appears, showing the error message string. An error provider is a better alternative than displaying an error message in a message box, because once a message box is dismissed, the error message is no longer visible. It is typically used in conjunction with validating user input on a form, or displaying errors within a dataset. The Windows Forms ErrorProvider component is used to validate user input on a form or control.
