Three suggestions for you Lupin-III：）
1）In your aspx page，there should be something like UpdateParameters，please set DefaultValue="" for all the strings，and set ConvertEmptyStringToNull=True。
2）Check whether you've set DataKeyNames for GridView，or DataKeys for other controls like Repeater or something else。
3）Converting the Update to TemplateField，and then handle GridView_RowUpdating，plz use something like e.Command,e.Parameters to debug to see what's happening……
