RadzenButton doesn't call method written in Click

I have this code for every Institute block:

<RadzenRow class="my-1 py-1" Style="border:1px dotted #ccc;align-items:center;">
    <RadzenColumn Size="2" SizeLG="1" class="text-center">
    <RadzenColumn Size="10" SizeLG="7">
    <RadzenColumn Size="6" SizeLG="2">
        <RadzenButton Click="@Edit" Color="Color.Warning">Edit</RadzenButton>
    <RadzenColumn Size="6" SizeLG="2">
        <RadzenButton Click="@Delete" Color="Color.Error">Delete</RadzenButton>

It renders correctly (except colors of buttons), but when I click on button it do nothing.
I have tried using @onclick, but it didn't solve my problem.

My Program.cs contains this line
and VisualStudio says that it is correct (and correctly builds it)

There are my App.razor (.NET 8.0)

Thanks, I didn't find the place, where I need to place @rendermode, but now i've added it to the Router element. So button clicks really call needed methods.

Can be set on every component:

When i using it only with RadzenButton, it throws me an exception. But server works correctly, after I written it to the Router element
