Customizing the ListBox

The ComboBoxVisual includes a ListBoxInstance which can be customized or completely replaced.

The following code shows how to change the ListBox background:

var comboBox = new ComboBox();
comboBox.AddToRoot();

var comboBoxVisual = (ComboBoxVisual)comboBox.Visual;

var listBoxVisual = comboBoxVisual.ListBoxInstance;
listBoxVisual.Background.Color = Color.DarkGreen;
listBoxVisual.Name = "ListBoxInstance";
comboBoxVisual.ListBoxInstance = listBoxVisual;

for(int i = 0; i < 10; i++)
{
    comboBox.Items.Add($"Item {i}");
}
