Describe the bug
I have a List that displays a couple of categories / tags. I call the load function in the OnNavigatedTo
method and it works as far as it displays the items after a second or so. But the busy indicator does only show up, when I add a await Task.Delay(10)
before my data are loaded from SQLite (fun fact Delay(5) seems to be not sufficient as well ^^).
Any idea why that is and what I'm doing wrong?
public void Initialize()
{
Loader.Load(_ => LoadCategories());
}
private async Task<List<CategoryGroup>> LoadCategories(string searchTerm = "")
{
// Why has this to be here?
await Task.Delay(10);
var categories = await mediator.Send(new GetCategoryBySearchTermQuery(searchTerm));
var categoryVms = categories.Select(c => new CategoryListItemViewModel { Id = c.Id, Name = c.Name, RequireNote = c.RequireNote }).ToList();
var groupedCategories = categoryVms.GroupBy(c => c.Name[0].ToString(CultureInfo.InvariantCulture).ToUpper(CultureInfo.InvariantCulture))
.Select(g => new CategoryGroup(title: g.Key, categoryItems: g.ToList()));
return new(groupedCategories);
}
