The ErrorProvider control in the Windows Forms framework provides a simple-to-understand abstraction for presenting errors on input. Also, the ErrorProvider can alert the user to more than one error at a time.Īnd: Having to dismiss more than one dialog is extremely obnoxious to your busy users. The ErrorProvider alleviates this frustration. A frustrating experience for a computer user is getting dialog boxes that demand your entire attention. Setting BlinkStyle to NeverBlink is appropriate.ĭialogs. Tip: For more complex interfaces, the blinking could draw attention to the error. Note: Typically, for less complicated user interfaces, blinking isn't necessary because the ErrorProvider will be easy to see. And the BlinkStyle lets you disable or enable blinking in general. The BlinkRate indicates how many milliseconds each blink is apart. The ErrorProvider has two properties related to blinking. This instantly tells our user that no error is still present.īlinkStyle. If a digit was located, we simply remove the error sign from the user interface. It is also important that you use the Clear method when appropriate. The first argument tells the ErrorProvider where to draw the error sign. The second argument is the error message itself. The first argument of SetError is the identifier of the TextBox control. Call SetError or Clear on the ErrorProvider.ĮrrorProvider1.SetError(textBox1, "Needs to contain a digit") Determine if the TextBox has a digit character. Private void textBox1_TextChanged(object sender, EventArgs e) When the TextChanged event handler is triggered, we check to see if a digit character is present.Īnd: If one is not, we activate an error through the ErrorProvider. In the example, we have a TextBox control and a TextChanged event handler on that control. It will be invoked through other event handlers in the program. The ErrorProvider won't initiate any actions. We must activate the ErrorProvider in our Windows Forms program. Note: Some properties and methods on the ErrorProvider are detailed in the following sections.Įxample. Next: You can change properties on the ErrorProvider instance by right-clicking on it and selecting Properties. This will insert the errorprovider1 into the tray at the bottom of the screen. Find and double-click on the ErrorProvider icon. To start, please open the Toolbox pane in Visual Studio. It does not require a lot of work on your part. It is an abstraction that shows errors on your form. This C# article demonstrates the ErrorProvider control in Windows Forms.ĮrrorProvider simplifies and streamlines error presentation. ![]()
