  The majority of the C1 WinForms input controls seem to honour any application-wise custom CultureInfo Date Format settings. But C1DateEdit does not do so, it only seems to honours the system CultureInfo Date format settings.

  The attached demo solutions showcases the problem. Program.cs sets the custom application-wide custom Short Date Pattern. The demo Form contains just a C1TextBox and a C1DateEdit. Both are set to today’s date and FormatType: ‘ShortDate’. Only C1TextBox (and other C1 controls like C1TrueDbGrid) honours the custom Short Date Pattern, but C1DateEdit does not.

  Hello,

  Thank for the sample. We could observe the behavior as well and thus escalated it to the development team for further insights. [Internal Tracking ID: C1WIN-35246]

  We’ll get back once we have more information.
