Radgrid Template Column Header Export to PDF & Excel
I have added Listview in Header template in Template column, its showing the data on the grid as expected. When I am exporting to Excel or PDF its not exporting the header. Header you see in headertemplate.jpg is not exporting to PDF
In the sample project you have shared I can see that Telerik Document Processing library is being used to build the export output on a Button click. Building the output manually is not related to RadGrid's built-in export functionality.
In order to use RadGrid's built-in functionality to export to PDF using a Button's click, you will need to call the ExportToPDF() method of the grid. This in fact exports the required document as expected.
