public System.ComponentModel.MaskedTextResultHint RejectionHint { get; }

member this.RejectionHint : System.ComponentModel.MaskedTextResultHint

Public ReadOnly Property RejectionHint As MaskedTextResultHint

Property Value

MaskedTextResultHint

A MaskedTextResultHint that generally describes why the character was rejected.

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the MaskedTextBox.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 MessageBox.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 MaskedTextBox.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

Remarks

The MaskInputRejectedEventArgs property is set in the MaskInputRejectedEventArgs constructor.
