.Requirement

But I found this control don't support dateformat property,I think the ms why don't support this property.

Thread.CurrentThread.CurrentCulture = (CultureInfo)Thread.CurrentThread.CurrentCulture.Clone(); Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern = "yyyy/M/d"; 

 

 

// make sure the past date isn't selectable.
