How to create an XML PlaceholderToBind property from a userControl ..

Hello all, I have created a userControl that will be dragged and dropped in

all of my MCMS templates. Actually I am using Susan Warren's XMLEditGrid 
source code to create a userControl that will allow users to add data. 
For 
example, lastName, firstName, addresss etc.  The userControl works just
fine.
  However, I now would like to use it in all my MCMS templates.  The
problem 
is that when I drag and drop the userControl, I cannot bind the
XMLEditGrid 
userControl to an XMLPlaceholder because the PlaceholderTobind property
does 
not exist.  So I am required to code the PlaceholderTobind property in the

XMLEditGrid userControl.  Below is my source code VB.NET for the 
PlaceholderTobind property.  

   <Bindable(True), Browsable(True), Category("Data"), Description("Name
of 
the XML PlaceHolder.")> _
        Public Property XMLPlaceHolder() As McmsWebControlLibraryVB.
McmsWebControlLibraryVB.McmsXmlPlaceholderVB
            Get
                Dim s As McmsWebControlLibraryVB.McmsWebControlLibraryVB.
McmsXmlPlaceholderVB = CType(ViewState("XMLPlaceHolder"), 
McmsWebControlLibraryVB.McmsWebControlLibraryVB.McmsXmlPlaceholderVB)
                If s Is Nothing Then
                    Return Nothing
                End If
                Return s
            End Get
            Set(ByVal Value As McmsWebControlLibraryVB.
McmsWebControlLibraryVB.McmsXmlPlaceholderVB)
                ViewState("XMLPlaceHolder") = Value
            End Set
        End Property

However, it does not work.  Does anyone have any ideas .....


Thank-you all in advance
