Public static readonly BindableProperty AutoPlayProperty Public static readonly BindableProperty AspectProperty Use this instead: var valor = value?.Public class MediaElement : View, IMediaElementController The above can make your application crash if value is null. The second option can be accomplished this way:Īs you can see we are now accessing them through the CollectionView Binding, we do this when we specify the Source and use a Reference.

The first one will give you more flexibility but at the same time might add repeated code (if all the items will share the same color for example). If you want to make it work: either add these two properties ( TextColor and ButtonBackColor) to the GroupModel class or change the binding so that these two properties are accessed from the parent Binding. The same way the nombre property you are binding to the Label Text Property, is part of the GroupModel class, that way the TextColor and ButtonBackColor properties are expected to be part of the same class you did bind as the ItemSource. You are using a CollectionView and when you set the ItemSource Your issue is not with the ValueConverter but with your Bindings.

I have a label with black text color inside a frame with white background color, the thing is, I want to assign the background color and text color from the viewmodel, I have created the converter, and did the bindings, but for some reason it isn't working
