My xamDataGrid use theme Office2010Blue. I want to programmatically set the first row be default selected. The first time load is OK, the first row background color is orange. But when I submit a query to reload or refresh the grid, the first row background color is silver. How to make it still be orange color? I use the following code:

          record.IsActive = true;
          record.IsSelected = true;

But doesn't work, once grid refresh or reload, the record background color becomes silver.

Thanks,
