Dear Ryan,

Hiding a button can be easily done in ViewModel through data binding. You don't need a service to do that. Since service is singleton, the best practice for service is typically used for non UI related tasks. To learn more about MVVM and data binding in Crosslight, please refer to the article here.

Crosslight comes with several pre-built bindable properties to help developers accomplish common tasks easily. Specifically for your case, you can bind the IsVisible property against the property in your ViewModel and the button. This allows you to set the property to true/false in ViewModel, which consequently reflects the visibilityof the bound view. You can find out the complete bindable properties in our class API reference here.

To learn more how MVVM and data binding works, I highly suggest you to check our comprehensive MVVM samples from our Git server here  There are some examples showing IsVisible property, as well as many others such as opacity, text,value, and more.

Hope this helps.

This only helps one case, but what if I need to modify the image nativaley after it is set?

Like do the following:

                  UserImage.Layer.MasksToBounds = true;                    UserImage.Layer.CornerRadius = UserImage.Frame.Height/2;

Hello Ryan,

The view-specific properties such as appearance aren't common to be implemented as bindable properties. That's because each platform has their own type and API which differ with other platforms. In Crosslight, we designed the bindable properties to cover most user interaction logic that can be well separated from the view.

The good news is that Crosslight also allows you to create your own bindable properties, so you can create binding for certain properties not supported in Crosslight. This can be easily done through binding adapter, a mechanism that Crosslight itself uses internally for the built-in MVVM-aware components.

You can see an example of binding adapter in our Crosslight - Syncfusion chart binding sample which is a bit quite advanced. We are planning to publish a simpler sample with walkthrough later this week. At the meantime, you can try to learn from the chart binding sample to grasp the concept.

Hope this helps.
