view model

private observablecollection<user> _users;   public userviewmodel() {    _users = new observablecollection<user>(getallusers());  // paging control   viewlist = new collectionviewsource();   viewlist.source = users;   viewlist.filter += new filtereventhandler(viewfilter);    currentpageindex = 0;   itemcount = users.count;   calculatetotalpages(); }  #region deletecommand      public icommand deleteusercmd     {         { return new relaycommand(k => deleteuser(currentselecteduser)); }     }      // delete user database.     private void deleteuser (user user)     {         if(currentselecteduser != null)         {             using (var usermanager = new usermanager())             {                 messageboxresult msgresult = messagebox.show("are sure delete user?", "delete user?", system.windows.messageboxbutton.okcancel, messageboximage.asterisk);                 if (msgresult == system.windows.messageboxresult.yes)                 {                     return;                 }                 usermanager.delete(user);                 messagebox.show("user deleted!", "confirm!", messageboxbutton.ok, messageboximage.asterisk);                  // refresh listview after delete record.                 users.remove(user);             }         }         else             messagebox.show("you must select user!", "warning!", messageboxbutton.ok, messageboximage.exclamation);       }      #endregion 

model

public collectionviewsource viewlist { get; set; }  public observablecollection<user> users     {                 {             return _users;         }         set         {             _users = value;             onpropertychanged("users");         }     } 

edit: translation error? notice korisnici bosnian "the users"

what viewlist.view you're binding itemssource to?

anyway, you're presumably binding items property "users", hence why calling onpropertychanged("users") when want update list.

however, you're removing user "korisnici":

// refresh listview-a after delete record. korisnici.remove(user); onpropertychanged("users"); 

not "users" collection. unless korisnici.remove method have created? korisnici? think want:

// refresh listview-a after delete record. users.remove(user); 

note, don't need onpropertychanged("users") - managed observablecollection, implements inotifycollectionchanged notify of changes collection.
