  I notice that your sample only groups by one column. Is it possible to group by multiple columns?

  Hi Andy,

  Yes, you could group the multiple columns in FlexGrid. The GroupAsync method takes array of GroupDescription that you could use to group multiple columns. Kindly refer to the following code snippet and the attached sample:

      protected override async Task OnInitializedAsync()
      {
          forecasts = await ForecastService.GetForecastAsync(DateTime.Now);
          var dataCollection = new C1DataCollection<WeatherForecast>(forecasts);
          await dataCollection.GroupAsync(new GroupDescription("Summary"),
          new GroupDescription("Date"));
          forecastsDataCollection = dataCollection;
      }
