Not sure if this is the issue.Check the spelling of the columnname, it's incorrect item["FisrtName"] = TextBox1.Text; My SharePoint Blog http://dhireny.blogspot.com

Hi Wasi, Here are some possible scenarios 1) Permission Issue: This can be a permissions issue as the user running the web part may not have enough permission to the List/Site. You can probably trying using RunWithElevatedPrivileges if it works for you. http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spsecurity.runwithelevatedprivileges.aspx http://firstblogofvarun.blogspot.com/2009/06/how-to-use-runwithelevatedprivileges-in.html http://blog.qumsieh.ca/2008/02/28/configure-your-code-to-run-with-elevated-privileges/ 2) Check your column name 3) Check the data type of the column (as per your example this should be Single Line of Text) 4) Check the Site name if it correct (http://wasi, try to provide FQDN in the site name) 5) While debugging which line in your code is throwing error. HTH Thanks, Skancharla
