    I am currently setting up a RadChart with custom filters and can not seem to get the chart to clear if there is no data when ViewState is enabled. When I set ViewState to false it works great, the only problem is the chart OnClick event does not fire if ViewState is set to false, and the click event is something this chart has to have.

    For example, this should clear the chart so it shows the error message if there is no data returned:

    dataPoints= bll.GetAllCustomerDataPoints(param1, param2);
     
    if (dataPoints.Count > 0)
    {
         UpdateCustomerChart(dataPoints);
    }
    else
    {
         RadChart1.Clear();
    }

    Hello,

    We were unable to reproduce the problems you are experiencing in our local tests -- please review the attached sample applications that demonstrate our observations (clearing chart with Viewstate, click event with disabled viewstate) and let us know if we are missing something out.


    Kind regards,
