Introduction

Use the CheckBox control to allow the user to select a true or false state.

If you plan to use multiple CheckBox controls, the CheckBoxList control is an alternative control that provides convenient data binding capabilities. However, individual CheckBox controls provide greater control over layout.

Important

A CheckBox control accepts user input, which is a potential security threat. By default, ASP.NET mobile Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
