Hi,
I am using this link for your example for chart to embed RadChart instances in template column of RadGrid.
http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandchart/chartingrid/defaultvb.aspx?product=chart
               I am using VS 2010 and ADO.net entity data model and EntityDatasource instead of sqldatasource, the issue is chart is not being rendered for all roows except the last one.. I am getting an error at the statement  chart.DataSource = SqlDataSource2.Select(DataSourceSelectArguments.Empty) 'Value of type system.web.ui.DataSourceSelectArguments cannot be converted to integer.
What i use is  chart.DataSource = EntitylDataSource2.Select(DataSourceSelectArguments.Empty). 
 The chart for the  last row of the grid  is displayed only, can you please advise?  Please see the result attached when I use
EntityDataSource2.WhereParameters(0).DefaultValue = item.GetDataKeyValue("Entity1").ToString()             chart.DataSourceID = "EntityDataSource2"             Commented out'chart.DataSource = EntityDataSource2.Select(DataSourceSelectArguments.Empty)Here is my definition of EntityDataSource2
<asp:EntityDataSource ID="EntityDataSource2" runat="server"             ConnectionString="name=TEntities" DefaultContainerName="TEntities"            EnableFlattening="False" EntitySetName="Entities"                                     Select="it.[Entity1], it.[Type], it.[Entity_Desc], it.[Active], it.[Cnt], it.[Dataupdtthru]"             EntityTypeFilter="" OrderBy="it.[Entity1]"     Where="it.[Entity1] = @Entity">           <WhereParameters>     <asp:Parameter  DbType="string"   Name="Entity"  />  </WhereParameters>   </asp:EntityDataSource>
