Assembly: System.Web (in System.Web.dll)
[ControlValuePropertyAttribute(L"Checked")] [AspNetHostingPermissionAttribute(SecurityAction::LinkDemand, Level = AspNetHostingPermissionLevel::Minimal)] [AspNetHostingPermissionAttribute(SecurityAction::InheritanceDemand, Level = AspNetHostingPermissionLevel::Minimal)] public ref class CheckBox : public WebControl, IPostBackDataHandler, ICheckBoxControl
Use the control to allow the user to select a true or false state.
If you plan to use multiple controls, the CheckBoxList control is an alternative control that provides convenient data binding capabilities. However, individual controls provide greater control over layout.
A 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.
The markup rendered by default for this control might not conform to accessibility standards such as the Web Content Accessibility Guidelines 1.0 (WCAG) priority 1 guidelines. For details about accessibility support for this control, see ASP.NET Controls and Accessibility.
The following example demonstrates how to use a control to indicate whether tax is included in the calculation for a sales total.
The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information on the Web Forms code model, see ASP.NET Web Page Code Model.
