ASPxClientDockManager.PerformCallback(parameter) Method

Sends a callback to the server and generates the server-side ASPxDockManager.Callback event, passing it the specified argument.

Declaration

PerformCallback(
    parameter: string,
    onSuccess?: (arg: string) => void
): void

Parameters

Name	Type	Description
parameter	string	A string value that contains any information that needs to be sent to the server-side ASPxDockManager.Callback event.
onSuccess	(arg: string) => void	A client action to perform if the server round-trip completed successfully.

Remarks

Use the PerformCallback method if you need to asynchronously go to the server and perform 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 (for instance, in the “Name = Value;” form) via the PerformCallback method’s parameter 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 ASPxDockManager.Callback event. The method’s parameter argument is passed to the event’s handler as the CallbackEventArgsBase.Parameter property. So, the necessary server-side actions can be performed in the event’s handler based upon the values of the arguments which can be obtained by parsing the passed information string.
