I need help implementing INotifyPropertyChanged in my own data structure class. This is for a class assignment, but implementing INotifyPropertyChanged is an addition that I am doing above and beyond what the rubric requires. I have a class named 'BusinessRules' that uses a SortedDictionary to store objects of 'Employee' type. I have a DataGridView showing all of my employees, and I want to use my BusinessRules class object as the DataSource for my DataGridView. The BusinessRules container is required for the assignment. I have tried to implement INotifyPropertyChanged in this class, with no

i have this Base class : public abstract class WiresharkFile { protected string _fileName; protected int _packets; protected int _packetsSent; protected string _duration; public int Packets { get { return _packets; } set { _packets = value; } } public int PacketsSent { get { return _packetsSent; } set { _packetsSent = value; } } } And this sub class: public class Libpcap : WiresharkFile, IDisposable, IEnumerable<WiresharkFilePacket> { .... } Create my object: WiresharkFile wiresahrkFile = new Libpcap(file); My collection: public ObservableCollection<WiresharkFile> wiresharkFiles { get; set; }

From my usercontrol I tried to show value inside a listbox named PersonList Usercontrol Code: BindingList<NotifiablePerson> PerSonList = new BindingList<NotifiablePerson>(); SqlCommand prsonListCmd = new SqlCommand("SQL QUERY", conn); SqlDataReader dr = prsonListCmd.ExecuteReader(); if (dr.HasRows) { while (dr.Read()) { //collect value from database and save inside Fname and Lname variable NotifiablePerson np = PerSonList.AddNew(); np.FirstName = Fname; np.LastName = Lname; } } PersonList.DisplayMember = "np.FirstName" + "np.LastName"; PersonList.ValueMember = "np.FirstName"; PersonList

I am currently implementing an Extension for the INotifiyPropertyChanged interface, you can read this: INotifyPropertyChanged - Event stays null for furhter information. Now I would like to extend this extension further so that I dont need to state the MemberExpression and when calling it from inside a set that the CallerMemberName Attribute does the rest. So I have tried to do the following (based on the links provided in my last stackoverflow question): public static void Notify(this PropertyChangedEventHandler EventHandler, object sender, [CallerMemberName] String propertyName = "") { if

I have been binding in WPF application directly to the model classes (and skipping creating individual viewmodel classes). Now, after switching to EF6 and DBContext, I face an issue with the generated EF POCO classes since it looks its either kind of tricky or not even recommended trying to make INotifyPropertyChanged interface implemented directly to those classes. Currently: I don't want to go back to ObjectContext. I don't want to change T4 too much either. The suggestions on the web for changing T4 to achieve INotifyPropertyChanged looks too error-prone for me. Creating viewmodels for each

I have found an implementation of Propperty Changed Event, where i can Call Property changed without the Name of the Property in the web. And then i have build a Extension Method with it wich is here public static void OnPropertyChanged(this INotifyPropertyChanged iNotifyPropertyChanged, string propertyName = null) { if (propertyName == null) propertyName = new StackTrace().GetFrame(1).GetMethod().Name.Replace("set_", ""); FieldInfo field = iNotifyPropertyChanged.GetType().GetField("PropertyChanged", BindingFlags.Instance | BindingFlags.NonPublic); if (field == (FieldInfo) null) return; object

Try to understand WPF. This is my test classes: public partial class MainWindow : Window, INotifyPropertyChanged { private ObservableCollection<string> _myList = new ObservableCollection<string>(); public ObservableCollection<string> MyList { get { return _myList; } set { _myList = value; RaisePropertyChanged("_myList"); } } public MainWindow() { InitializeComponent(); comboBox1.DataContext = _myList; } private void button1_Click(object sender, RoutedEventArgs e) { MyList = AnotherClass.SomeMethod(); } public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged
