The LOD of RadRotator gives you the possibility to show as many items as you want on each request. This being said you should go through the following steps:
1) Use some standard technique to extract only 4 records from teh XML - e.g use XmlReader, etc - this is general ASP.NET knowledge and it is not directly related to RadControls
2) Form the HTMl for the item based on the extracted data and return the 4 items back to the rotator
3) The rotator will be populated with the returned items only. After that, it will automatically understand when it is needed to load additional items when going to next or previous and will call your method in teh WebService again, you should read and form the next 4 items, etc.
To better understand how this is done, please examine the demo below:
On a side note, when you install RadControls, our online examples projects are automatically installed on your computer and you can not only examine their full source code, but also extend them further in order to meet your requirements.
You can open the demos from here:
Start\Programs\Telerik\RadControls for ASPNET AJAX\Open Sample WebSite In VisualStudio
The actual location on your hard disk is the following one:
C:\Program Files\Telerik\RadControls for ASPNET AJAX \Live Demos
I hope that this information is helpful.
