Where to call Datagrid.GotoPage

Using version 3 of the component library I used the GotoPage() method of a datagrid in the OnInitializedAsync after setting the datasource, eg.

 protected override async Task OnInitializedAsync()
        Data= await Data.ListAsync();
// int page = ...  coming from parameters or querystring and checked if > 1 and <= (recordCount / Grid.PageSize) + 1
        await Grid.GotoPage(page); 

Now it doesn't work anymore, but it works in OnAfterRenderAsync(bool firstRender)

Is it correct to call here?

And btw, when should I set to true the second parameter forceReload?

Reference to a comment was never available at this stage, only after render. This is how Blazor works and it’s not related to Radzen Blazor components.
