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.
Errorprovider clear code#
following code example demonstrates using the ErrorProvider class to notify the user of a data entry error.
Private void textBox1_Validating(object sender, e) Private void button1_Click(object sender, System.EventArgs e) / The main entry point for the application. += new System.EventHandler(this.button1_Click) / the contents of this method with the code editor. / Required method for Designer support - do not modify
Errorprovider clear windows#
#region Windows Form Designer generated code Protected override void Dispose( bool disposing ) TODO: Add any constructor code after InitializeComponent call Required for Windows Form Designer support Es geht so einfach! Das folgende Beispiel zeigt, dass der über ShowDialog modal angezeigte Dialog trotz Fehlermeldung des ErrorProviders über den Abbrechen-Button geschlossen werden kann:
