Situation : When I cli

Answer 1

In order for the binding to be bidirectional, from control to datasource and from datasource to control the datasource must implement property changing notification events, in one of the 2 possible ways:

• Implement the INotifyPropertyChanged interface, and raise the event when the properties change :

  public string Name 
  {
    get
    {
      return this._Name;
    }
    set
    {
      if (value != this._Name)
      {
          this._Name= value;
          NotifyPropertyChanged("Name");
      }
    }
  }
  

• Inplement a changed event for every property that must notify the controls when it changes. The event name must be in the form PropertyNameChanged :

  public event EventHandler NameChanged;
  
  public string Name 
  {
    get
    {
      return this._Name;
    }
    set
    {
      if (value != this._Name)
      {
          this._Name= value;
          if (NameChanged != null) NameChanged(this, EventArgs.Empty);
      }
    }
  }
  

  *as a note your property values are the correct ones after window maximize, because the control rereads the values from the datasource.
