Hi,

I am tring to call a javascript function when a date is selected using the date picker. I am using the onchange event of the embedded DateInput control. When I type in a date this works fine. When I select a date from the calendar, the onchange event is not being raised. Should I not expect the onchange event to be raised when the date is set using the calendar? If not, what event would I use?

Thank You.

Hi Roger Manderville,

I guess you want to call a JavaScript function on selecting the date from RadDatePicker. You can call the JavaScript on OnDateSelected="ondateselected" event of RadDatePicker to achieve this.

ASPX:

    
            <telerik:RadDatePicker ID="RadDatePicker1" Runat="server"> 
        
                        <ClientEvents OnDateSelected="OnDateSelected"/>             
        
            </telerik:RadDatePicker>

JavaScript:

    
            <script type="text/javascript"> 
        
            function OnDateSelected() 
        
            { 
        
                //statements 
        
            } 
        
            </script>

Thanks,
Shinu.

Hi Shinu,

Actually, I am calling local web services as described in the article below:

http://asp.net/ajax/documentation/live/tutorials/ExposingWebServicesToAJAXTutorial.aspx

I construct the web service call dynamically in code and then assign the call using attributes.add (for the standard controls). I also allow the programmer to pass in javascript code to be executed before the call and after.

With the date picker I am using ClientEvents.OnDateSelected and assigning the web service call to this property but I get the following error:

Microsoft JScript runtime error: Sys.InvalidOperationException: Handler must be a function.

Any ideas?

thanks,
Roger
