There is some problem by use ContextMenu in xamDataGrid,it like this

<igDP:XamDataGrid.ContextMenu>
                <ContextMenu x:Name="ContextMenu1" StaysOpen="true" HasDropShadow="False" Placement="RelativePoint">
                    <MenuItem Header="Delete" Command="{x:Static igDP:DataPresenterCommands.DeleteSelectedDataRecords}"  />
                </ContextMenu>
            </igDP:XamDataGrid.ContextMenu>

but when i click rightbutton ,the menuItem(Delete) is disenable and after i click one record ,the menuItem(Delete) is enable,how to enable the

menuItem without leftbutton choose a record,i want to use rightbutton only to Delete record but choose the record with leftbutton first,thanks!
