  string txt_Company = ((TextBox)e.Item.FindControl("txt_Company")).Text;
  string txt_Address = ((TextBox)e.Item.FindControl("txt_Address")).Text;

------解决方案--------------------------------------------------------
除了ID，是不是其它全部是字符类型的？
如果不是，不要所有的字段都加上单引号
------解决方案--------------------------------------------------------
ID是不是String. 
试试这个
+ txt_Note + " ' WHERE id='" + editID.ToString() + "'"; 

------解决方案--------------------------------------------------------
提示什么错误？
WHERE id=" + editID.ToString(); 在where前面加个空格试试；
------解决方案--------------------------------------------------------
最好的办法，单步调试；把jmgUpdateData的代码拷贝到查询分析器里执行，再根据错误的提示查找问题；
------解决方案--------------------------------------------------------
lz仔细点就好了。
------解决方案--------------------------------------------------------
如果Id是数字：
 ....'" + txt_Note + " ' WHERE id=" + editID
------解决方案--------------------------------------------------------
