The grid exposes a number of events that are fired when the CRUD operations execute, and they let you access the new data, and get notified that something changed. You definitely need to use them to update the actual database (e.g., call a web service or an existing data access layer logic), and perhaps you can add there a call that will perform the desired reloading (maybe a JS interop call to a signalR hub that you already have running). I am not sure how one can reload a view in Blazor, apart from changing data which would re-render relevant parts of the view, though, so once you have that C# logic running, you should be able to call it from the grid events. I must note here a related bug - see this page (I've already added your vote to raise its priority, because it is likely to affect you).
That said, if you create such an example, I'd encourage you to post it here and we'll gladly award your contribution with Telerik points. Of, if you prefer, open a pull request in the following repo: https://github.com/telerik/blazor-ui.
