Silverlight list will not update with new source

I have a list linked to a shared list, whenever I removed an item from the shared list and rewrite it into the list, it still shows the deleted items. Here is the code:

            InventoryList.Remove(currInv);         
            lstSubMenu.ItemsSource = InventoryList;
            lstSubMenu.DisplayMemberPath = "InventoryItemName";

I have checked the shared list and the item is removed and no error occurs in the output window.

Install ItemsSource = null

before you set it as InventoryList

.



However, it is generally best to set the property ItemsSource

once and never again. You can do this using ObservableCollection

. Once you do that, you can add / remove your heart content and not worry about the binding target not updating.
