Asked On May 10, 2019 02:46 PM UTC

I am using server-side blazor and the EjsMultiSelect control. At runtime, the dropdown appears to work fine but during any operation throws the following exception in the browser console:

Uncaught (in promise) Error: System.ArgumentException: The assembly 'Syncfusion.EJ2.RazorComponents' does not contain a public method with [JSInvokableAttribute("UpdateModel")].
