Sends a callback to the server and generates the server-side ASPxRichEdit.Callback event, passing it the specified argument.
PerformCallback(parameter: string, onSuccess?: (arg: string) => void): void
A string value that represents any information that needs to be sent to the server-side event.
|onSuccess||(arg: string) => void||null||
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 PerformCallback method's args 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 ASPxRichEdit.Callback event. The method's args argument is passed to the ASPxRichEdit.Callback 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.
