Hello,

Yes, we call that CSOM (Client Side Object Model) and there is a lot of documentation and examples in our online help repository:

http://help.infragistics.com/NetAdvantage/NET/2008.2/CLR2.0/

(the last link in the treeview on the left, then navigate to UltraWebGrid).

You may also try taking a look at our DevCenter -

A lot of UltraWebGrid KB articles are located there, including client-side (javascript) ones.
