So I have been able to narrow down a bug that started with a the .net core preview 9 update. I have already updated to the latest prerelease version of devexpress.blazor. The issue is that I cannot update the a child component's DxDataGrid from a parameter in the parent. It displays the first list, but it then fails with:
Microsoft.JSInterop.JSException: Could not find 'DxBlazorLoaded' in 'window'.
Error: Could not find 'DxBlazorLoaded' in 'window'.

Any ideas?
