Listbox drag and drop

[psyk]

Hello, 

I have a page with multiple ListBox with AllowDragAndDrop set to true. During the OnDropped event I want to know wich ListBox is receiving the dragged items. I have seen that the DropEventArgs class contains the Target property wich is now deprecated. What are the alternatives to use?

I have raised a separate post for this (links to this post) but it does not seem at all obvious how to actually use the DropEventArgs<T>.Target property to identify which ListBox is receiving the drop.

I cannot work out how to either fetch any identifying information from the listbox (even including a @ref pointing at a ListBox<TItem, TValue> field in the code) or how to set anything.

The ElementReference provided by Target has an Id Property but this seems to be a generated number and I can't see how to associate this with any particular ListBox control.
