DataGridView SelectionChanged fires when other properties are being set.

HI!

I have a DataGridView, bound to a SortableBindingList on my presentation model. I also have several other controls bound to properties of the same model. They're all updated OnPropertyChanged. My problem is, for every property that is being updated, after selecting a row on the DGV, the SelectionChangedEvent is being fired twice. Because of this, when I select a row, the SelectionChanged event is fired like 13 times. I don't see how the properties bound to other controls are connected to the DGV, other than them sharing a bindingSource. Could someone explain this to me and maybe give some suggestions on how to avoid this sort of behaviour? Is there a better event to catch than SelectionChanged? I'm very close to going back to manual synchronization.

            shopSalesPresentationModel.SelectedShopSaleIndex= shopSalesDGV.SelectedRows[0].Index;}}
