Hi, Siva Sankar

Thanks for replying. And I've got the error format date value in enteredValue, and change them like strings below.

平成26年12月
平成07年09月03日
1995年09月03日
不明
2014年12月
2014年

What if I just want to set these values to the ultraCalendarCombo controls, is that prossible to implement?

Thanks for your concern.

Hi, Dimitar

Thanks for replying. With the request return back, I'm still trying with this.

And I was wandering if I want to show the value "平成27年04月28日" in the ultraCalendarCombo, is it possible to implement that?

Does it have to like the topic below:

Could you please help me with that? Thanks for your concern.

P.S. "平成27年04月28日"  is actually Japaness calendar, and in culture "en-US" it's "2015/04/28".

Hi Siva,

Thank you very much for your suggestions in this thread.

Richard, do you have any additional questions on this matter?

I am looking forward to hearing from you.

Hi Richard,

Try to parse the value which you entered to DateTime. If parsing is success then you can set that as Value of UltraCalenderCombo. 

Ex: 

private void ultraCalendarCombo1_ValidationError(object sender, DateValidationErrorEventArgs e)
{
     string enteredValue= this.ultraCalendarCombo1.Text;
     DateTime ValueAfterParse;
     bool ValidDate = DateTime.TryParse(enteredValue, out ValueAfterParse);
     if (ValidateDate)
     {
         this.ultraCalendarCombo1.Value = ValueAfterParse;
      }
}

Thanks,

-Siva
