Hello,  I'm trying to bind data to a chart using the RadDomainDataSource however my chart is not returning values.  Below is the code I'm using.  I would like to know first of all if I have everything set up correctly?  I also wanted to know if "DataView" in the ItemSource should be unique per project, or will it be the same all the time?

 

 

 

<telerik:RadDomainDataSource x:Name="xRadDomainDataSource" QueryName="GetProtocolsQuery" 
                                                                    AutoLoad="True">
            <telerik:RadDomainDataSource.DataContext>
                <service:iTRACKContext/>
            </telerik:RadDomainDataSource.DataContext>
  
        </telerik:RadDomainDataSource>
              <telerik:RadCartesianChart x:Name="chart" Width="222">
                    <telerik:RadCartesianChart.HorizontalAxis>
                        <telerik:CategoricalAxis/>
                    </telerik:RadCartesianChart.HorizontalAxis>
  
                    <telerik:RadCartesianChart.VerticalAxis>
                        <telerik:LinearAxis Maximum="100"/>
                    </telerik:RadCartesianChart.VerticalAxis>
  
                    <telerik:RadCartesianChart.Series>
                        <telerik:BarSeries CombineMode="Stack" ItemsSource="{Binding DataView, ElementName=xRadDomainDataSource}" ValueBinding="Duration" CategoryBinding="FundingID"
                                           ShowLabels="True">
  
                         
                        </telerik:BarSeries>
                    </telerik:RadCartesianChart.Series>
  
                </telerik:RadCartesianChart>

Hello Mindy,

From the code you shared I can't see any immediate problem. The chartview is a data control and can visualize any data that is in the form of IEnumerable.  You can place a gridview in the place of your chartview to see if the data is reachable.

I have prepared for you a small project that demonstrates how you can databind chartview to RIA services.
