Main API Members

The list below outlines key members of the TcxCheckBox class. These members allow you to configure check box editors.

Appearance Settings

Style | StyleDisabled | StyleFocused | StyleHot | StyleReadOnly

Allow you to define individual appearance settings for different editor states.

Tip

To apply the same style settings to multiple editors, use a TcxEditStyleController component. If you need to apply the same style settings to all editors in your application, you can use a TcxDefaultEditStyleController component.

Styles

Provides access to individual styles applied to the editor in different states.

Transparent

Specifies if the check box is transparent in GDI render mode.

Content-Related APIs

State | Toggle

Note

You need to set the Properties.AllowGrayed property to True to add the grayed (intermediate) state to the check box editor.

Editor Settings and Repository Items

ActiveProperties

Properties
