Paging based on groups in Radgrid not working

Question

Hi,

We are not able to implement paging on the basis of groups. For example we have 5 groups and have 10 rows in each group then if we set page size to 4 then first 4 groups should be displayed and 5th group should be displayed on 2nd page. But what happens is that only 4 rows of Ist group is displayed and 12 page numbers were created.

We have to implement paging based on groups while it is happening based on total records in the groups.

Please help. Its urgent.
