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
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.

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.
