I have a grid with three bands , ViewType = OutlookGroupBy and loadonDemand = XMl
when I group by a column only first row of that group is expanded , rest rows could not be expanded ,
When + sign of 2,3,... row is pressed the grid is refreshed and no data is displayed
If you've got a datarelation set up in your dataset, you don't need outlook groupby. you should just set the grid to Hierarchical, and it will show the relation as set in your database.
Hope this helps,

Is this still the case with the latest releases of the WebGrid? I am able to assign a DataSet with a DataRelation to a LoadOnDemand=XML grid with ViewType=OutlookGroupBy. The first bad always works, however subsequent bands are not showing up, the grid just reloads itself.
OutlookGroupBy and LoadOnDemand=XML will not work together (unfortunate, I know). Your best bet it so nest the grid inside of an UpdatePanel so that the grouping can occur without a traditional postback. unfortunately though, you will not be able to leverage the bandwidth friendly load on demand during a row expand.
