ListView is not rendered

[DerTev]

Any idea, why the ListView is not rendered?
As you can see, the List contains an element.

        foreach (var step in Steps!) StepKeys.Add(step.Key);

        Title = "ABC";

        var length = new Label("Length: " + StepKeys.Count);

        var stepSelection = new ListView(StepKeys);

        var exitButton = new Button
        {
            Text = "Exit",
            X = Pos.Left (stepSelection),
			Y = Pos.Bottom (stepSelection) + 1
        };

        Add(length, stepSelection, exitButton);
    }

Most likely this is because you have not specified a size for the ListView.

Try:

var stepSelection = new ListView(StepKeys) { Y = Pos.Bottom(length), Height = 5, Width = 20 };

Ah, that works, thanks!

Is Height here the height of items that would fit in the height of the element?

Height of element.
