Export to PDF and print radgridview

[ANTONIO]

Hi, I have a problem with the Raddatagrid, use this example:

http://demos.telerik.com/silverlight/#GridView/PrintAndExportWithRadDocument

but I get an exception in this part 

public RadDocument CreateDocument(RadGridView grid)

        {

List<GridViewBoundColumnBase> columns = (from c in grid.Columns.OfType<GridViewBoundColumnBase>()                                       orderby c.DisplayIndex select c).ToList();

when you save the file, says the value is null when I debug the program I see the value of parameter is null, as not properly send the grid, which can be my mistake
