The CustomDrawNodeCheckBox event's data class is DevExpress.XtraTreeList.CustomDrawNodeCheckBoxEventArgs.
The event parameter provides you all the information necessary to paint a node check box (see Node Checking - Checkboxes and Radio Buttons). The Node property returns the node currently being painted.
See the Custom Draw Scenarios topic for information on using custom draw events.
