I’m using the MS sample (https://github.com/dotnet/blazor-samples) as it’s about all I need to re-write reports for a legacy DB. I notice it seems to reload from the DB without interaction from me i.e. just opening the home page. It seems like it’s going into home.razor a number of times (e.g. it hits my breakpoint on _lastPage initialization) causing it to query the DB each time. With the simple/local DB they use that’s not much of a performance issue but with a real/remote DB it adds a lot of time.
So what’s triggering the ‘refresh’ and can/should I avoid it?

In MVC, I handled the “session_start” event to load user details and store them in a session variable, so I didn’t have to query the database with each page load.

I have a SSR Parent component with a Child component with InteractiveServer render mode. I need this child component to be interactive so that I can bind to events like @onclick etc. I want to pass data/value back to the parent using EventCallback but this delegate is never set I guess due to different render modes, is there another way to do this?

Folks, i have looked but not able to find an answer to what i imagine should be pretty straightfotward.
