	* Binding.cs: When acquiring a BindingManagerBase for the first time,
	check that the specified property actually exists in the data source,
	and throw an ArgumentException if that's not the case - this is only
	done for this scenario, since for later cases (such Position changes)
	we throw different exceptions (match .Net).
