 [Adminauthorize] public actionresult Eidt (UserGroup usergroup) {usergrouprsy = new usergrouprepository ();
 var _usergroup = Usergrouprsy.find (usergroup.usergroupid); if (_usergroup = = null) {Error _e = new Error {Title = "user group does not exist", Details = "errors occurred while modifying the user, the modified user group does not exist." ", cause =" The user group has been deleted by another administrator ", Solution = Server.URLEncode (" <li> return <a href= ' "+ url.action (" List "," usergroup ") +" ' &
 gt; user group List </a></li> ")};
 Return redirecttoaction ("Manageerror", "Prompt", _e);
 } _usergroup.name = Usergroup.name;
 _usergroup.description = usergroup.description; if (Usergrouprsy.update (_usergroup)) {Notice _n = new Notice {Title = "modified successfully", details = "Successfully modified user group information", Dwelltime = 3, n
 Avigationname = "user group list", Navigationurl = url.action ("list", "UserGroup")};
 Return redirecttoaction ("Managenotice", "Prompt", _n); else {Error _e = new Error {Title = ' update data failed ', details = ' modified information when modifying user group information failed to be saved to the database.
