ASPxClientTreeList.PerformCallback(args) Method

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

Declaration

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

Parameters

Name	Type	Description
args	string	A string value that represents any information that needs to be sent to the server-side ASPxTreeList.CustomCallback 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 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.
