): void
| Name | Type | Description |
|---|---|---|

A string value that represents any information that needs to be sent to the server-side ASPxTreeList.CustomCallback event.

A client action to perform if the server round-trip completed successfully.

Use the PerformCallback method if you need to asynchronously go to the server and perform some server-side processing using AJAX-based callback technology. You can pass the required information which can be collected on the client side as a string of arguments, via the arg parameter. The onSuccess parameter allows you to specify a client function that should be executed after the server round-trip completed successfully.
The PerformCallback method posts back to the server using the callback technology, and generates a server-side ASPxTreeList.CustomCallback event. The method’s arg argument is passed to the ASPxTreeList.CustomCallback event’s handler as the TreeListCustomCallbackEventArgs.Argument property.
