I am using the GridGroupingControl with DataSourceCachingMode set to "None" PostBackOnFocusedChanged set to True and PostBackOnRowDblClick set to true.  I am handling the OnDemandDataSourceLoad and the OnDemandTotalRowCount events and my paging is working properly and I want to implement/add filtering functionality.

My problem is that since I am paging, when the list of items for the column is displayed (when the filter dropdown for a column is clicked) that only items in the current page of data is displayed.  In other words, if I have 14 rows in the entire data set and the first 12 are shown on the first page of data and the last 2 are shown on the second (last) page then the list of filterable items on the last page only show information from records on the last page - no "filter items" are shown from the first page.

Is it possible to get the list of items (or provide a list of items) that appear in the dropdown for each filterable column or is there an event I can handle like the OnDemandDataSourceLoad or OnDemandTotalRowCount events to supply the list of items that appear in the dropdown list for each column?
