# ListBoxItem

## Introduction

The ListBoxItem class is used by the ListBox control for each instance added to the ListBox.Items property.

Gum Forms includes a default ListBoxItem implementation which includes a single label.

## Code Example: Adding ListBoxItems

ListBoxItems can be implicitly instantiated by adding any type of object to a ListBox. The following code creates 20 ListBoxItems, each displaying an integer.

```csharp
// Initialize
var listBox = new ListBox();
listBox.AddToRoot();
listBox.X = 50;
listBox.Y = 50;
listBox.Width = 400;
listBox.Height = 200;

for(int i = 0; i < 20; i++)
{
    listBox.Items.Add(i);
}
```
