Datagrid does not update after changing items

[pseudo summit]

Hey. I am new to Fluent UI and having some difficulty with datagrid.
I have a FluentDataGrid to show list of model. I want to filter the items according to a property. When i query and update the items and use updateDataAsync() method, datagrid does not update and at the end of the method browser gives error.
How am i suppose to update DataGrid when items list changes?

This is my datagrid:

<FluentDataGrid @ref="@MealGrid" TGridItem="Meal" Items="@FilteredMeals" ShowHover="true" ResizableColumns=true Pagination="@pagination" GridTemplateColumns="0.2fr 0.1fr 0.1fr 0.6fr 0.2fr 0.2fr" RowClass="@rowClass" RowStyle="@rowStyle" Style="height: auto;overflow:auto;">

this is the method triggered for filtering:

 private async Task FilterMeals()
  {
      IQueryable<Meal> tempMeals;
      if (!string.IsNullOrEmpty(searchValue))
          tempMeals = FilteredMeals.Where(x => x.Foods != null && x.Foods.Any(food => food.Name.ToLower().Contains(searchValue.ToLower())));
      else
          tempMeals = meals;

      if (tempMeals != meals && tempMeals!=null)
          FilteredMeals = tempMeals;

      searchValue = null;
      mealFilter = "All";
      await MealGrid.RefreshDataAsync();
         
  }

The page is working in interactiveserver mode.All other components works well.
i have debugged the method and the query is working well. FileteredMeals (which datagrid uses as items) updates according to filtering. But the grid does not update.

Thanks.

You have to update the @FilteredMeals query set. But I see you are already doing that.. 🤔

I have refactored the linque query with nested loops and it works well now. But I coulnt understand why this linque query caused a problem (debugging seems ok )

this is how i refactored

List<Meal> tempMeals=new();
if (!string.IsNullOrEmpty(searchValue))
{
    foreach (var meal in FilteredMeals){
        foreach (var food in meal.Foods)
        {
            if (food.Name.ToLower().Contains(searchValue.ToLower()))
            {
                tempMeals.Add(meal);
                break;
            }
        }
    }
    FilteredMeals = tempMeals.AsQueryable();

}
else
{
    FilteredMeals = meals;
}
