Bind nullable DateTime to MaskedTextBox

Question

I have a masked text box bound to a nullabe datetime, but when the date is blanked out, the validation on the masked text box won\'t complete. Is there a way to force this

Answer 1

This should work:

private void Form1_Load(object sender, EventArgs e)
{
    maskedTextBox1.Mask = "00/00/0000";
    maskedTextBox1.ValidatingType = typeof(System.DateTime);
    maskedTextBox1.TypeValidationCompleted += new TypeValidationEventHandler
       (maskedTextBox1_TypeValidationCompleted);
}



private void TypeValidationCompletedHandler(object sender, TypeValidationEventArgs e )
{
    e.Cancel = !e.IsValidInput &&
        this.maskedTextBox1.MaskedTextProvider.AssignedEditPositionCount == 0;

}
