I am developing an application on ASP.net with c# as the code behind. I am using Infragistics UltrawebGrid to display data. Whenever, the value of any cell changes, UpdateCell event is fired.

I just want a message box (rendered thru javascript) on that event.

My code is

Code:
UltraWebGrid1.Attributes.Add("onupdatecell","javascript:return confirm (\"Are you sure? This action cannot be rolled back. \");");
But, nothing pops up. It doesn't give any error also.

Pls help.
