    I have been looking for a working example of a LINE CHART that uses a linqdata source.  They have an example of a bar chart, and I changed out the series type with a telerik:lineseries and it is just not working.  


    I am sure I am just missing something very easy here...  Does anyone know of an example combining these two?

    This should be stupid easy I would think.

    I have have already replied to the support ticket that was opened by you on the matter, so that I paste my answer for the rest of the community:

    You can find the modification of this demo (, so that a line series is bound to LinqDataSource:

    <asp:LinqDataSource ID="LinqDataSource1" runat="server" OnSelecting="LinqDataSource1_Selecting">


    <div class="demo-container size-wide">

        <telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="800px" Height="500px"




                    <telerik:LineSeriesDataFieldY="UnitsInStock" Name="Units In Stock">

                        <TooltipsAppearance Visible="false"></TooltipsAppearance>


                    <telerik:ColumnSeries DataFieldY="UnitsOnOrder" Name="Units On Order">

                        <TooltipsAppearance Visible="false"></TooltipsAppearance>



                <XAxis DataLabelsField="ProductName">


                    <MajorGridLines Visible="false"></MajorGridLines>

                    <MinorGridLines Visible="false"></MinorGridLines>



                    <TitleAppearance Text="Units"></TitleAppearance>

                    <MinorGridLines Visible="false"></MinorGridLines>



            <ChartTitle Text="Products Balance">





    protected void LinqDataSource1_Selecting(object sender, LinqDataSourceSelectEventArgs e)


        NorthwindReadOnlyEntities northwindContext = new NorthwindReadOnlyEntities();

        e.Result = northwindContext.Products.Where(p => p.UnitsOnOrder > 0).Where(p => p.UnitsInStock > 0).Take(5);


    The above chart renders like that -

    You can find the live demos in the installation folder of Telerik UI controls. For example here:

    C:\Program Files (x86)\Telerik\UI for ASP.NET AJAX Q1 2015\Live Demos

    Let me know if you have any questions on the matter.
