Question

Is it possible to create a textbox or other control that is bound to a variable or property?
I want to have a control that will show the current value of a control and update the variable with a new value if the control changes.

Is there some control I could download that already has this?

Answer 1

Would DataBindings be what your looking for? Binds a control to a property :

myTextbox.databindings.add("text", classWithProperty, "propertyName")

That’s how I did it in VB.NET, but i’m a bit rusty.

EDIT:

I believe you need to implement iNotifyPropertyChanged for the values to update:

Public Class YourClassWithProperty
Implements INotifyPropertyChanged

Then make a function :

Public Sub OnPropertyChanged(ByVal name As String)
    RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs(name))
End Sub

After, call the function in your property’s “set” area :

Example :

Public Property Name() As String
    Get
        Return personName
    End Get
    Set(ByVal value As String)
        personName = value

        OnPropertyChanged("Name")
    End Set
End Property
