Exporting to Excel from Telerik Gridview in Silverlight

Here is the sample code for exporting Telerik Gridview in silverlight.

private void btnExportOrders_Click(object sender, RoutedEventArgs e)
{
   // Checking whether grid has rows
    if (OrderGrid.Items.Count > 0)
    {
          string extension = "xls";
          string selectedItem = "Excel";
          ExportFormat format = ExportFormat.ExcelML;
          SaveFileDialog dialog = new SaveFileDialog();
          dialog.DefaultExt = extension;
          dialog.Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, selectedItem);
          dialog.FilterIndex = 1;
          if (dialog.ShowDialog() == true)
          {
              using (Stream stream = dialog.OpenFile())
              {
                GridViewExportOptions options = new GridViewExportOptions();
                options.Format = format;
                options.ShowColumnHeaders = true;
                options.Encoding = Encoding.UTF8;
                options.ShowColumnHeaders = true;
               // name of the grid which you want export      
                OrderGrid.Export(stream, options);
               }
           }
     }
     else
      {
         // User friendly Message
          MessageBox.Show("There are no records to export.", "Export Warning!", MessageBoxButton.OK);
      }
 }

This export code will also support different formats like CSV,Text and HTML. All you need to change is the enum type for ExportFormat to above formats and the extension. Its easy and simple. Good luck
