How to pass a parameter to razor component in server-side Blazor?

Question

How can I pass parameter into razor component?

So far I tried

@(await Html.RenderComponentAsync<Rateplan>(RenderMode.ServerPrerendered, new { id= 100}))

But I receive an error

InvalidOperationException: Prerendering server components with parameters is not supported.

I try the same thing with RenderMode.ServerPrerendered but I receive an error

InvalidOperationException: Server components with parameters are not supported.

I also tried doing

<Rateplan Id="100"></Rateplan>

but that didnt even start the component.

In the component where you want to accept the parameter you need to have a Property marked as a parameter

Like

[Parameter]
public List<Player> Players { get; set; }

Then you should be able to pass in the parameter as

<Componentname Players="@players"></Componentname>

(In this example @players is a local variable)
