Question

I have a MonoTouch iPhone app which has a UITableViewController as it’s main view controller.

I am trying to detect when the tableview is being scrolled with the code:

this.TableView.Scrolled += TableViewScrolled;

where TableViewScrolled(object sender, EventArgs e) { } is my method being called.
But it fails to call the TableViewScrolled() for some reason.

Does anyone have any experience with this?

@Krumelur’s comment on the previous answer makes a very good point and IMO should have been an answer (not a comment).

The point is that if your set a Delegate (or WeakDelegate) to your UITableView then it’s events won’t work anymore.

Why ? because to implement those events MonoTouch creates it’s own internal delegate type for UIScrollView (the parent of UITableView) where it overrides the methods (of the delegate) and expose them as, more natural (in .NET), events inside the type.

This effectively means that you cannot mix those UITableView events with your own delegate UITableViewDelegate type (since the later will override the former).
