I am trying to retain expanded and selected columns in my radgrid with a detailview after row drop from another grid.
I am following the guides here and have set EnableAJAX="False" on my RadAjaxManager. My problem is that the ItemCommand event is not fired unless it performs a sort.

here is the grid I am trying to retain select and Expand Collapse on

    
            <telerik:RadGrid ID="rgGroups" runat="server" OnItemCommand="rgGroups_ItemCommand"

Code Behind (although it doesn't reach this):

    
             Protected Sub rgGroups_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgGroups.ItemCommand 
        
                    'save the expanded/selected state in the session 
        
                    If e.CommandName = RadGrid.ExpandCollapseCommandName Then 
        
                        'Is the item about to be expanded or collapsed 
        
                        If Not e.Item.Expanded Then 
        
                            'Save its unique index among all the items in the hierarchy 
        
                            Me.ExpandedStates(e.Item.ItemIndexHierarchical) = True 
        
                        Else 
        
                            'collapsed 
        
                            Me.ExpandedStates.Remove(e.Item.ItemIndexHierarchical) 
        
                            Me.ClearExpandedChildren(e.Item.ItemIndexHierarchical) 
        
                        End If 
        
                        'Is the item about to be selected  
        
                    ElseIf e.CommandName = RadGrid.SelectCommandName Then 
        
                        'Save its unique index among all the items in the hierarchy 
        
                        Me.SelectedStates(e.Item.ItemIndexHierarchical) = True 
        
                        'Is the item about to be deselected  
        
                    ElseIf e.CommandName = RadGrid.DeselectCommandName Then 
        
                        Me.SelectedStates.Remove(e.Item.ItemIndexHierarchical) 
        
                    End If 
        
                End Sub

I would appreciate any help as I am lost.
