I have a problem and I can't figure out how to solve.

1.  I'd like to present a list of records, grouped by a single column and the default (initial) presentation to the user should have the group collapsed, hiding the detail records for the user.  (I think we've got this one figured out).

2.  in addition to 1 above, I would like to apply the grouping on the server side before the Page size is applied.  The end result being if we have a Page Size of 10, we will show 10 groups, collapsed, regardless of how many detail records there are.  Basically set the paging on the grouping not the total number of detail records.

Any thoughts on how to accomplish this will be greatly appreciated.

Hi Bo,

The groups could be collapsed initially by calling the collapseGroup method once the Grid's dataBound event is triggered. I am afraid however, that displaying 10 groups with a pageSize of 10 is only possible if there is only one item in each group. In case the user is not allowed to change the grouping options, then you could use a hierarchical Grid as a workaround.
