Export a RadLinearSparkLine embed in a GridViewDataControl to Excel

[Javier]

Hi

I have a RadTreeListView with a custom column that is a RadLinearSparkLine, as follow

<telerik:RadTreeListView .......>
   <telerik:GridViewDataColumn DataMemberBinding={Binding field1}....>
   <telerik:GridViewDataColumn DataMemberBinding={Binding field2} ....>   
   <telerik:GridViewDataColumn DataMemberBinding={Binding field3} ....>
      <telerik:GridViewDataColumn.CellTemplate>
         <Datatemplate>
            <telerik:RadLinearSparkLine ItemsSource={Binding DiccionaryWithTheValues} ....... />
         </Datatemplate>
.....
.....

This works fine. It shows a grid with data and a graphic column based in the values from the "DiccionaryWithValues"

This grid needs to be exported to Excel. We use the Export method of the object RadTreeListView, but it doesn´t export correctly the RadLinear column. Instead of the chart, it exports a text wich represent a data type.

It is posible to export the chart with the Export method in anyway?????

Thanks

Hello Javier,

In order to be able to export the chart, you need to define a custom column and override the GetCellContent method as explained in this article.

I hope you find this helpful.
