[RESOLVED] Databindings for label on a winform usercontrol

[KR525]

I'm creating a usercontrol for a winform app that contains two labels, one as a header and the other one needs to bind to a datasource through Me.usercontrol1.databindings.add(). I'm a novice in usercontrol designing so I searched on internet to find how to make a databindings for my control. I realized that I need to use ControlBindingsCollection but I don't know exactly how.

I found following codes and added to my usercontrol :

Private bindingContext_ As BindingContext
Private dataBindings_ As ControlBindingsCollection
Public Overrides Property BindingContext() As BindingContext
    Get
        If bindingContext_ Is Nothing Then
            bindingContext_ = New BindingContext()
        End If
        Return bindingContext_
    End Get
    Set(ByVal value As BindingContext)
        bindingContext_ = value
    End Set
End Property
<DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _
Public Overloads ReadOnly Property DataBindings() As ControlBindingsCollection
    Get
        If dataBindings_ Is Nothing Then
            dataBindings_ = New ControlBindingsCollection(Me)
        End If
        Return dataBindings_
    End Get
End Property

Now I can set usercontrol1.databindings parameters but there's obviously something missing because I need to connect a single returning value from this binding to label2.Text in my usercontrol and I don't know how.

Is there anybody to help me solve my problem ?

Thanks in advance.

If all your binding is data members from one database row, then just bind the controls you need to be bound:

Private _data as DataRow

Public Sub New(ID as integer)
InitializeComponent()

' set the me._data to the data returned from the database table using ID

Me.Label1.DataBindings.Add(New Binding("Text", me._data, "Title"))
Me.Label2.DataBindings.Add(New Binding("Text", me._data, "Value"))

End If

If you need to browse through the rows, look into the BindingNavigator.

Dear MonkOFox,

It worked perfectly.

Thanks again.

That's great! If you don't mind, use the thread tools to mark it resolved. : )
