c# - How to fill MatBlazor SelectItem after an event?

Question

I am pretty new to MatBlazor. I am trying to fill a MatSelectItem with some options after something happens.

Initial locations = new LocnamesItem[] {};

<MatSelectItem Disabled="@(!locationvisible)" Label="Select Location" Value="@selectedLocation" Items="@locations" TValue="LocnamesItem">
    <ItemTemplate>
        <span>@context?.Locname - @context.Locdescr </span>
    </ItemTemplate>
</MatSelectItem>

There is a login happening after which I fill the locations array with data.

        locationList = await LoginProcess.GetLocations(login.sysUserId);
        locations = locationList.ToArray();
        StateHasChanged();

Unfortunately the options don't appear after statehaschanged call.

Regular select control with options building works well with similar code.

Answer 1

It was the learning curve. Adding the services.AddMatBlazor() at StartUp.cs resolved the issue.
