ComboBox with predefine string values in dockpane

ModyBuchbinder — Tue, 16 Sep 2025 14:07:12 GMT

I am trying to put a ComboBox in my dockpane with pre defined string values (Something like Polygon/Polyline/Point). They never change.

All the examples I found have ObservableCollection with some classes or other complex behavior that I do not need.

My ComboBox is coming out empty.

Anybody have very simple example on how to do it?

Thanks

Hi,

You can do it from xaml:

Already done this.

It does not looks like MVVM - is that the only way?

XAML:

ViewModel:

public List<string> GeometryTypes => new List<string>() { "Polygon", "Polyline", "Point" }; public string SelectedGeometryType { get; set; } = "Polygon";

After playing a lot (and consult AI) this is my solution

XML

Helper class:

public class MyItemClass { public string Name { get; set; } }

Fill the list

private ObservableCollection<MyItemClass> _TypesItems; // fill the list in ctor TypesItems = new ObservableCollection<MyItemClass> { new MyItemClass { Name = "Item 1" }, new MyItemClass { Name = "Item 2" }, new MyItemClass { Name = "Item 3" }, }; public ObservableCollection<MyItemClass> TypesItems { get => _TypesItems; set => SetProperty(ref _TypesItems, value); }

and finally get the selected

private MyItemClass _selectedType; public MyItemClass SelectedType { get => _selectedType; set => SetProperty(ref _selectedType, value); }

There is a community sample that shows how to do this:
