Question

Can I use VB.Net's generics to simply Wpf notifiable bound controls?

Answer 1

Here's how to use VB.Net's Generics to create notifiable bound controls.
Class MainWindow
Public Sub New()
InitializeComponent()
Me.DataContext = Me
End Sub
Public Property NoNotify As String = "No notify"
Public Property DoesNotify As New NotifiableProperty(Of String)("DoesNotify")
Private Sub TestBtn_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles TestBtn.Click
NoNotify = "Won't Show"
DoesNotify.Value = "Notified!"
End Sub
End Class
Public Class NotifiableProperty(Of T)
Implements System.ComponentModel.INotifyPropertyChanged
Sub New()
End Sub
Sub New(ByVal InitialValue As T)
value = InitialValue
End Sub
Private m_Value As T
Public Property Value As T
Get
Return m_Value
End Get
Set(ByVal value As T)
m_Value = value
RaiseEvent PropertyChanged(Me, New System.ComponentModel.PropertyChangedEventArgs("Value"))
End Set
End Property
Private Event PropertyChanged(ByVal sender As Object, ByVal e As System.ComponentModel.PropertyChangedEventArgs) Implements System.ComponentModel.INotifyPropertyChanged.PropertyChanged
End Class
