In Blazor Server, for things like drag and drop or any mouse movement events, you should avoid tying them to server-side handlers, but you can also just write JavaScript code. The backend needs to know what to render, not necessarily where, you can keep it on the frontend.

You can also just use Blazor WASM, but I've had trouble setting up Windows Authentication when in Blazor Server it works out of the box.
