title: Telerik DataSource, paging and filtering
body: <p>I have a Telerik RadGrid.  The initial DataSource that is bound to the grid has 145 records.  I have filering turned on in the grid as well as paging and my pagesize is 20.  When I filter down to 75 records, the MasterTableView.Items collection of the grid shows 20 records.  This matches what's in the grid being displayed.  However, I need to perform a Mass Change on the data and need the 75 filtered records.  Is there somewhere in the Grid that has the 75 filtered records?  I want to avoid having to get all 145 records again and then manually filtering.</p>
