public event C1WebChartCallbackEventHandler GeneralCallback

Public Event GeneralCallback As C1WebChartCallbackEventHandler

The event handler receives an argument of type C1WebChartCallbackEventArgs containing string data related to this event.

Use the client side General callback to pass your own data in string form to the server. Based on the content of your string data, you can change any and all aspects of the chart and obtain a new image and image map as a result of the callback.

The General callback is typically used when a callback from an input object on the web page is desired - e.g. a button, onclick.
