DropDownList Binding issue

[John]

Regarding the SfDropDownList in blazor.

We would like to be able to bind both the DataSource and Currently selected item to a view-model.

We get the following error when trying to bind 'Value' to a non-primative:

System.NullReferenceException: Object reference not set to an instance of an object.

         at Syncfusion.Blazor.DropDowns.DropDownListEvents`2.OnInitializedAsync()

         at Microsoft.AspNetCore.Components.ComponentBase.RunInitAndSetParametersAsync()

We can successfully bind to a .NET list/array/etc.. but we are struggling to bind to the current value, having to resort to events instead which is fragile.

Please advise, Thanks, John
