Thank you for getting back to me. I will wait for the December 23rd update.
Unfortunately the solution provided in the sample is inadequate. I need to access the data remotely from an API. In your sample, you are not touching the provided controller and have changed the code to load data in the OnInitialized method.
Is there any way to pass additional parameters to the CustomAdaptor constructor or read method? I could potentially have the customadaptor call the api but I would need to get the HttpClient to it somehow.
