'FetchData' does not exist in the current context

[Majestijn]

I imported this package with Nuget Package Manager, Added the using directive to my page and copied the sample code. I get the following error however: 'FetchData' does not exist in the current context.

Does this only work for Blazor WebAssembly? Because I'm using Blazor Server and don't have a _ViewImports.cshtml file to add the taghelper to.

I can see that being confusing. FetchData should have been declared in the example. That's a mistake that we'll have to fix.

That being said, FetchData is just your own method for retrieving data. e.g.: in the basic Microsoft starter app for Blazor, there is usually an injected WeatherForecastService. Here's how that might look with that service.

   @inject WeatherForecastService _forecastService
   // rest of code here
    protected override async Task OnInitializedAsync()
    {
        _data = await FetchData(_filter, _page);
    }

    private async Task<PagedResult<WeatherForecast>> FetchData(string filter, int page)
    {
       return await _forecastService.GetForecastAsync(DateTime.Now, page);
    }

Where the service code looks something like:

  public WeatherForecastService()
  {
      var rng = new Random();
      _summaries = new List<WeatherForecast>();
      var date = DateTime.Now;
      for (var i = 0; i < 48; i++)
          _summaries.Add(new WeatherForecast
          { Date = date.AddDays(i), Summary = Summaries[rng.Next(Summaries.Length)], TemperatureC = rng.Next(-20, 55), });
  }
 public Task<PagedResult<WeatherForecast>> GetForecastAsync(DateTime startDate, int page)
  {
      return Task.FromResult(_summaries
          .AsQueryable()
          .ToPagedResult(page, 10));
  }

ah I see, and what about the _ViewImports.cshtml where you have to add the @addTagHelper *,BlazorPagination. Is that important? Because I don't have that in my project

[villainoustourist]

That is also dated documentation and needs to be updated,

It should be simply adding @using BlazorPagination to the top of the page or component.

Sorry about that. We'll update the documentation accordingly to avoid that confustion.

I got it working. Very nice! Is there a way to style the pagination? Like center the content instead of justify-end? Or the colors?
