MWC uses MonoTouch.Dialog extensively!
Looking at the MT.D code, the Element.Selected method is usually
implemented like this:
public override void Selected (DialogViewController dvc, UITableView
tableView, NSIndexPath indexPath)
{
// dostuff
tableView.DeselectRow (indexPath, true);
}
If you create a custom Element for your app and implement RowSelected
without 'DeselectRow' it should work. You can probably also just subclass
the Elements you're already using and just override this one method... you
might want to make it conditional so that on the iPhone it DOES deselect.
MT.D is pretty extensible (and the source is available too). I'd be
surprised if you had to re-write as a UITableView...
