OK, I dug in some more and thought the RadClientDataSource might be the bridge for this. I cannot get that to work. Here is the code am using. When I call DataSource.fetch(); it come back empty. Any help would be appreciated!

function LoadSparkLineCharts(sender, eventArgs) {

debugger;

var masterTable = $find("<%=rgProjectDetails.ClientID%>").get_masterTableView();

var datePicker = masterTable.get_dataItems()[0].findControl('rcSparkLine');// Here 0 represents the index of crow in editmode

var dataSource = $find('<%= rcdsSparkline.ClientID %>');

var data = dataSource.fetch();

datePicker.set_dataSource(data);

}

<asp:SqlDataSource ID="sqlTest" runat="server"

ConnectionString="<%$ ConnectionStrings:PLEDB %>" SelectCommand="select datepart(month,EventTime) as [Month],datepart(year,EventTime) as [Year],count(*) as [Cnt] from Something OD

and od.EventTime>dateadd(year,-1,getdate())

group by datepart(month,EventTime),datepart(year,EventTime)

order by datepart(year,EventTime),datepart(month,EventTime)"></asp:SqlDataSource>

<telerik:RadClientDataSource ID="rcdsSparkline" runat="server" >

<DataSource>

<DataSourceControlSettings DataSourceID="sqlTest" DataFields="Month,Year,Cnt" />

</DataSource>

</telerik:RadClientDataSource>
