    Hello,
    OnSelectedDateChanged event of RadDatePicker(Prometheus) version control fires twice.  I have attached the code from a test project I have created to demonstrate the issue.  I cannot attach a file to the post so I am pasting the code here!.

            }  
        }  
    }  
     
    I am using Telerik.Web.UI dll with version # 2007.3.1314.20
    System.Web.Extensions Dll verison # 1.0.61025.0.
    I am not copying the web.config as I think it is unnecessary but let me know if you need it.
    Put a break point in the OnSelectedDateChanged event handler and notice how it will break twice of a singe click on the calendar.

    Your help is appreciated

    Thanks
    Raj

    Hi Raj,

    I was able to test locally reduced version of your code, due to missing resources. My test did not show the described problem and the event is fired only once.
    If it is convenient, could you please open a regular support ticket and send us a sample runnable project so we could investigate further.

    Best wishes,
    Maria Ilieva
