Remarks
Use the LiveCallback control to add callbacks to any non-PowerWEB control.
Usage requires implementation of two JavaScript functions (one that makes the callback and one to handle the response), and a server-side function to be triggered. See the topic Walkthrough: Manipulating Intrinsic Microsoft Controls in a Callback for more details.
Note The server-side function can have a maximum of nine parameters. All parameters must be strings.
