C1CommandControl is a command which can be associated with an arbitrary control. This functionality is provided by the class C1CommandControl, derived from C1Command. Controls can be dragged from the Visual Studio Toolbox and dropped onto a C1MainMenu or C1ToolBar. This automatically creates a C1CommandControl, connects it to the dropped control, and adds a link to the new command to the toolbar. This command allows at most one command link to be connected to it.
