I checked the page source. I think here is the problem. The update button is this: <a href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$ContentPlaceHolder1$DetailsView1$ctl12", "", true, "", "", false, true))" style="color:#333333;">Update</a> I think it should be: <a href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$DetailsView1$ctl12','')" style="color:Black;">Update</a>
cheers, sneha
