Hi,

The Format defines only date pattern for not-focused state. In input mode WebDateChooser can only use "digit" patterns, and only for all 3 fields (day, month, year).

Both those patterns are defined by CurrentCulture or they can be customized on level of particular control. For example, set Format="Long" and implement Page.OnLoad by something like below:

protected void Page_Load(object sender, EventArgs e)
{
  System.Globalization.CultureInfo ci = System.Globalization.CultureInfo.CreateSpecificCulture("en-EN");
  ci.DateTimeFormat.LongDatePattern = "ddd MM/dd/yy";
  ci.DateTimeFormat.ShortDatePattern = "MM/dd/yy";
  this.WebDateChooser1.CalendarLayout.Culture = ci;
}
