MaskInputRejectedEventArgs.Position Property

Definition

Gets the position in the mask corresponding to the invalid input character.

public int Position { get; }

Property Value

An Int32 value that contains the zero-based position of the character that failed the mask. The position includes literal characters.

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" );
}

Remarks

The Position property is set in the MaskInputRejectedEventArgs constructor.
