Usually the easiest way would be to use a web service for loading dynamically the rotator items, as this functionality is already built-in. For a reference here is the URL to the demo for LoadOnDemand - http://demos.telerik.com/aspnet-ajax/rotator/examples/loadondemand/defaultcs.aspx
If you decide to do a custom implementation you will need to recreate the build-in functionality. Here is a draft of the basic things that you will need to implement for this scenario:
- Create a handler that gets the needed image from the XML data file.
- The rotator needs to be set of type FromCode
- The advancing of the rotator should be a custom implementation and should be synchronized with the data loaded from the server.
- In the hander of the Ajax request the following client side API functions should be used: addRotatorItem and after that repaint of the rotator.
Basically implementing a custom solution appears to be more complex that creating a simple web service.
Hope this helps.
All the best,
