Examples
The following code example demonstrates the use of this type. In the example, an event handler reports on the occurrence of the MaskInputRejected event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing Show with Console.WriteLine or appending the message to a multiline TextBox.
To run the example code, paste it into a project that contains an instance of type MaskedTextBox named MaskedTextBox1
. Then ensure that the event handler is associated with the MaskInputRejected event.
private void MaskedTextBox1_MaskInputRejected(Object sender, MaskInputRejectedEventArgs e) {
System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Position", e.Position );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RejectionHint", e.RejectionHint );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "MaskInputRejected Event" );
}
Private Sub MaskedTextBox1_MaskInputRejected(sender as Object, e as MaskInputRejectedEventArgs) _
Handles MaskedTextBox1.MaskInputRejected
Dim messageBoxVB as New System.Text.StringBuilder()
messageBoxVB.AppendFormat("{0} = {1}", "Position", e.Position)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "RejectionHint", e.RejectionHint)
messageBoxVB.AppendLine()
MessageBox.Show(messageBoxVB.ToString(),"MaskInputRejected Event")
End Sub
