dynamically populate mvc listview

[Keri]

Hi,
I am new to both mvc and Telerik mvc components. Apologies if this is the wrong place to ask for assistance.

I am developing a page that has a menu that consists of a list of buttons that set up a category.
Below this I have an MVC Listview.
If say the "Travel" category is chosen then I want to change the listview to display "Travel" type information.
I know that I can make the button force a postback and then reload the page with "Travel" stuff.

I want to know if there is an ajaxy way of doing this.
ie I would like to make the listview change what it displays as the menu above it changes.

Any advice or help would be appreciated.

Thanks in advance.
