Hi,
Does MultiView support client side view switch?
so there is no refresh of whole page when switch to each tab view.
No it doesn't. If you notice how it renders, all the content from all the other views are completely gone from the page. You need to make a postback to have another view displayed.

Use the free Anthem.NET controls, this is the complete solution to your problem. They are the ajax enabled versions of vs components.
