public object CustomActionRouteValues { get; set; }

Property Value

Type Description

An object containing the Controller and Action names.


Use the client MVCxClientImageGallery.PerformCallback method if you need to dynamically update the ImageGallery by asynchronously going to the server (using AJAX-based callback technology) and perform server-side processing in the specified Action. Via the method’s data parameter, you can pass any information collected on the client to the server for further server processing.

The client PerformCallback method posts back to the server using the callback technology and is handled in an Action specified by the CustomActionRouteValues property. Any data passed via the method’s data parameter can be accessed on the server as a parameter of the specified Action. So, the necessary server-side actions can be performed in the handling Action based upon the value(s) passed from the client.

For instance, you can pass values as a hash table.

Client Script Code:

myImageGallery.PerformCallback({key1: value});

Controller Code:

ActionResult MyAction(int key1){

The ImageGallery automatically updates itself (it is re-rendered) after such a custom callback has been sent and processed on the server.
