Dynamic collection

[Rafucho25]

Hi, I would like to know if it is possible to use a dynamic collection as an itemsSource because the header and data don't have a defined structure(it's determined in runtime).

Hi @Rafucho25, It might be possible to support a dynamic collection as an ItemsSource, but it depends on how the data is structured at runtime. If you can share a sample of the collection you're using, I can take a look and see if it works as-is or if any changes are needed. If adjustments are required, I’ll consider them for a future release.

@Rafucho25 Sorry for the late reply. If I understand correctly, you need to add your data to a dictionary and create the bindings accordingly. This will provide an accurate display, but the built-in sorting and filter might not work properly, which you can override write your own logic. I will try to fix this issue in the upcoming release. Thanks

public ObservableCollection<IDictionary<string, object?>> Items { get; set; } = [];

Items.Add(new Dictionary<string, object?>
{
    [nameof(ExampleModel.Id)] = item.Id,
    [nameof(ExampleModel.FirstName)] = item.FirstName,
    [nameof(ExampleModel.LastName)] = item.LastName,
    [nameof(ExampleModel.Email)] = item.Email,
    [nameof(ExampleModel.Gender)] = item.Gender,
    [nameof(ExampleModel.Dob)] = item.Dob,
    [nameof(ExampleModel.IsActive)] = item.IsActive,
    [nameof(ExampleModel.ActiveAt)] = item.ActiveAt,
    [nameof(ExampleModel.Department)] = item.Department,
    [nameof(ExampleModel.Designation)] = item.Designation,
    [nameof(ExampleModel.Address)] = item.Address,
    [nameof(ExampleModel.Avatar)] = item.Avatar
});

[nameof(ExampleModel.Gender)] = item.Gender

Is it necessary that we use the example model dictionary? Any way to create our own one like Gender (which shows a ComboBox)?

This is just an example: my answer was that you can use dictionaries to bind data in TableView, meaning any dictionary with a key type supported by WinUI for binding. I believe it only supports int and string keys.

My problem was that the option Auto-generating Columns doesn't work with dictionaries or ExpandoObject, so I fixed it by creating the columns manually. Thanks for your help.
