Thank you for contacting us.
The ExcelML method exports data with current filtering and
sorting. This functionality is built in and there is no need to do
anything to enable it. When the RadGridView is grouped, the export should
populate the excel file as a nongrouped data. This is because MS Excel does
not support grouping in the same way as data grid.
Erwin is correct, however, that with current version of RadGridView we have a known issue and it does
not export any data from grouped grid. This has already been fixed
and will be available in the next SP2 release in the January 2009.
Please, excuse us for the inconvenience.
If you have other questions, do not hesitate to contact me again.
