c# - How do I update a listview item that is bound to a collection in WPF? -

-

In WPF, I have a ListView bound for code-behind a ObservableCollection By updating the item adds and removes items from the list.

I have an 'edit' button that opens a dialog and allows the user to edit the values ​​for the selected ListView item. However, when I change the item, the list view is not updated. I am assuming this because I am not actually adding / removing objects from the collection, but rather amending one of the items.

How do I tell the list view that it needs to synchronize the binding source?

You need to apply INotifyPropertyChanged to the item class, such as: 

  Class ItemClass: INotifyPropertyChanged {public int BoundValue {get {return m_BoundValue; } Set {if (m_BoundValue! = Value) {m_BoundValue = value; OnPropertyChanged ("BoundValue")}}} Zero OnPropertyChanged (string propertyName) {If (PropertyChanged! = Null) {PropertyChanged (New, PropertyChangedEventArgs (propertyName)); }} Int m_BoundValue; }

And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

I do not understand why this script does not work. It has something to do within AJAX PostScript / Function. Right now, when I submit my form, it runs php code on the same page.
