Hi again,

this works, but only in a UltraWebTab:

<ig:WebTab ID="SalesVolumeTabs" runat="server" Height="260px" Width="200px">
        <Tabs>
         
            <ig:ContentTabItem runat="server" Text="Diagramm" >
                <Template>
                    <%
                        SalesVolumeChart.DataSource = ViewData["SalesVolumeData"];
                        SalesVolumeChart.DataBind(); 
                    %>
                    <igchart:UltraChart ID="SalesVolumeChart" runat="server" 
                        DeploymentScenario-ImageURL="../Content/images/Chart.png" 
                        DeploymentScenario-FilePath="../../Content/images" 
                        EmptyChartText="Keine Daten vorhanden." ChartType="PieChart" Version="10.2" Height="240" Width="180" >
                    </igchart:UltraChart>
                </Template>
            </ig:ContentTabItem>

        </Tabs>
     </ig:WebTab>

I tried the same in the ExplorerBar (which was the first component to choose because of the linear alignment for mobile devices), but I always get Errors. Something like: <% %> tags can't be placed in the template section or that the component SalesVolumeChart is not known in the document.

Is there a way to get this working in an ExplorerBar, so that the chart is show in a group section of the ExplorerBar?

Thanks again, KurtJulius
