I would suggest you check our online demos for MultiSelect
(every one has an ASP.NET MVC version) or examine the offline demos part of the Telerik UI for ASP.NET MVC bundle. You can also check the Telerik MultiSelect for ASP.NET MVC documentation
. There you can find more information how to setup the widget and if needed to send additional parameters with every server request. Let me know if you need further help.
