Unexpected behaviour using Xamarin.Forms 2.0 about ffimageloading

[daniel-luberda]

I do not understand what do you mean by "While is scrolling the image do not load. The first image loaded is repeated." Could you explain it in details?

The same image is repeated, don't you see? And this was working perfectly with XF < 2.0

Do you use new Xamarin.ListView items recycling feature (ListViewCachingStrategy.RecycleElement)? If yes, you should update ImageSource inside ViewCell OnBindingContextChanged override. Do you do that?

When the RecycleElement value is specified, OnElementChanged events are not raised when cells are recycled. Instead, the cell is retained and its property values change when the binding context is updated to that of an available cell, with OnElementPropertyChanged events then being raised.

@davidtavarez Any news?

I'm changing some logic in my code, I'll post the results :)

Any news?

If you use new Xamarin.ListView items recycling feature (ListViewCachingStrategy.RecycleElement), then it's not a FFImageLoading specific behavior. I advice to not use bindings in that case, instead inside ViewCell OnBindingContextChanged override you should:

• if BindingContext is null - handle it (important)
• clear, reapply transformations, cached image properties, etc, etc
• after that update ImageSource

Hi @davidtavarez. Do you still experience those issues?

[davidtavarez]

Yes, but I will find a solution soon.

@davidtavarez Any news? Did you try the latest alpha6?

[davidtavarez]

@daniel-luberda I found it! and is nothing related with CachedImage. Please, close this issue when I post the details.

[daniel-luberda]

Ok, if it's not FFImageLoading issue, I am closing it. Luckily, it looks like there are no more bugs to fix for the stable release! :P Thanks!
