System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

The following code example creates a class, named CustomHyperLinkDataBindingHandler, which derives from the HyperLinkDataBindingHandler class. It resolves design-time data binding for the CustomHyperLink class using the DataBindControl method.

' Derive a class from the HyperLinkDataBindingHandler. It will 
' resolve  data binding for the CustomHyperlink at design time.
Public Class CustomHyperLinkDataBindingHandler
    Inherits HyperLinkDataBindingHandler

    ' Override the DataBindControl to set property values in  
    ' the DataBindingCollection at design time.
    Public Overrides Sub DataBindControl( _
        ByVal designerHost As IDesignerHost, ByVal control As Control)

        Dim bindings As DataBindingCollection = _
            CType(control, IDataBindingsAccessor).DataBindings
        Dim imageBinding As DataBinding = bindings("ImageUrl")

        If Not (imageBinding Is Nothing) Then
            Dim hLink As CustomHyperLink = CType(control, CustomHyperLink)
            hLink.ImageUrl = "Image URL."
        End If

        MyBase.DataBindControl(designerHost, control)
    End Sub ' DataBindControl
End Class ' CustomHyperLinkDataBindingHandler
