How to add ContextMenu depending on which row of WPF DataGrid is right clicked?

Question

I need to display various parameters in ContextMenu depending on which row of WPF DataGrid is right clicked. My initial ideas were to accomplish this by binding or handling a mouse click event, but so far I have not had success with any strategy. Any help would be appreciated!

Thanks!

Private Sub InventoriesDataGrid_ContextMenuOpening( _

    ByVal e As System.Windows.Controls.ContextMenuEventArgs) Handles _
    InventoriesDataGrid.ContextMenuOpening

    Dim context = DirectCast(e.OriginalSource, System.Windows.FrameworkElement).DataContext

    If TypeOf context Is Inventory Then
        InventoriesDataGrid.ContextMenu = InventoriesDataGrid.Resources("DefaultContextMenu")
    Else
        e.Handled = True 'Do not show context menu.
