C1ToolTip client side has a very rich client-side object model since most of its members are identical to the members in the server-side control.
When a C1ToolTip control is rendered, an instance of the client-side tooltip will be created automatically. This means that you can enjoy the convenience of accessing properties and methods of the C1ToolTip control without having to postback to the server.
Using C1ToolTip's client-side code, you can implement many features in your Web page without the need to send information to the Web server which takes time. Thus, using C1ToolTip's client-side object model can increase the efficiency of your Web site.
