    Hello 

    in http://www.telerik.com/help/wpf/radchartview-populating-with-data-chartdatasource.html is this sample 

    public class MyDataSource : ChartDataSource
    {
        public MyDataSource()
            : base()
        {
            this.ValueAggregateFunction = new SumFunction();
        }
    }


    We used that with version 2012.3.1017.40 and it work fine for us. 
    Now we tried to upgrad to version 2012.3.1129.40 and is doesnt work. The property "ValueAggregateFunction" is not available

    Hi Ulrich,

    Presently, the ValueAggregateFunction is indeed missing due to some changes the ChartDataSource had to go through. Our developers are already working on fixing the issue. We apologize for the inconvenience. 

    All the best,

    Has this been fixed yet?

    I have looked through the release notes of the internal builds and cannot see it mentioned anywhere....

    Hi Peter,

    The support for custom aggregate functions has returned however there were some changes. Please refer to this forum post for more information. I have attached a sample demonstrating how they are used.

    The project you have attached does not work. GetValueAggregateFunction is not available to override. I am using 2012.3.1129.40 how can I get this to work?

    Hi Peter,

    The project my colleague attached depends on assemblies from our latest release with build number 2013.1.220. Since you still have an active subscription, you can download the latest version of RadControls for WPF from your account and I'd like to encourage you to do so.
