Description Hakan 2016-09-21 10:44:11 UTC
I think it is unclear what is meant by: "This can be accomplished by setting cell control properties in the OnBindingContextChanged override, rather than in the custom cell's constructor, as demonstrated in the following code example:" on https://developer.xamarin.com/guides/xamarin-forms/user-interface/listview/performance/.

The reason of binding is binding the property of the UI element to a property in the viewmodel. If so, what is the reason that the image source is updated in "OnBindingContextChanged"? When the binding of the cell changes due to recycling, image source should automatcally changes anyway, considering it is data bound.

Reworded the paragraph to make it clearer.
