I'm setting the culture of datepicker and use the code below.
    
        
i've set the IsReadonly= true so that the user cannot input by manually inputing a date, the code above is working fine, but when you click the DatePicker textbox and then click another control error is occured, "Object not set to a reference of object" any idea?
                                | CultureInfo cultureInfo = new CultureInfo("en-US"); | 
| DateTimeFormatInfo dateInfo = new DateTimeFormatInfo(); | 
| dateInfo.ShortDatePattern = "MM/yyyy"; | 
| cultureInfo.DateTimeFormat = dateInfo; | 
| radDatePicker1.Culture = cultureInfo; |
