ComboBox

Introduction

The ComboBox control provides a compact way for users to select from a list of options.

Code Example: Adding a ComboBox

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

Adjusting the Drop-Down ListBox

ComboBox provides a ListBox property which can be used to customize the ListBox instance.

This can be modified, even if it hasn't yet been shown. The following code shows how to modify the default size of the ListBox:

var comboBox = new ComboBox();
comboBox.AddToRoot();
comboBox.Anchor(Anchor.Top);
comboBox.ListBox.Height = 400;

for(int i = 0; i < 40; i++)
{
    comboBox.Items.Add($"Item {i+1}");
}
