Question

I am using Binding IsAsync property to keep UI responsive and loading data from the get accessor of the property and proved to be a good option while using MVVM. This approach is great and doesn’t need any manual code for async operations. There are few instances where my dataload is taking few seconds and during this time it is very difficult to differentiate between “no data” vs “data loading”. Is there a property which I can detect the state of the binding “IsBusy” or “Loading”, so that I can show some message that the loading operation is not complete?

Any help is appreciated.

According to the docs,

While waiting for the value to arrive, the binding reports the FallbackValue, if one is available, or the default value of the binding target property.

You can use this value to display a message to the user while the binding is loading.
