Filter problem with property binding

[Silvio del Balzo]

Hi,
first of all I'm sorry for my English.
I'm a new user, I'm trying to binding a fieldFilterDescription property  (value) to Textbox Property (text)
I used an example found in this forum "SilverlightGridCustomFilterRow"
In SilverlightGridCustomFilterRow the binding work well, but in my vb code WPF
the binding don't work.
When I change the textboxproperty don't change the fieldFilterDescription property
   
What's Wrong?

Dim ffd As FieldFilterDescription = Nothing

For Each cell As GridViewHeaderCell In cells
    Dim column As GridViewDataColumn = DirectCast(cell.Column, GridViewDataColumn)
    Dim descriptions As IEnumerable(Of FieldFilterDescription) = radGridView.FilterDescriptors.OfType(Of FieldFilterDescription)()
    ffd = (From fd In descriptions Where fd.FieldName = column.UniqueName Select fd).FirstOrDefault()

    Dim element As FrameworkElement = Nothing
    element = New TextBox()
    element.Height = 24
    element.Margin = New Thickness(3, 3, 3, 5)
    If ffd IsNot Nothing Then
       ffd.Filter1.[Operator] = Telerik.Windows.Data.FilterOperator.Contains
       BindText(element, "Value", ffd.Filter1)

    End If
next



Private Sub BindText(ByVal ptextBox As TextBox, ByVal pproperty As String, ByVal source As Object)

            Dim textProp As DependencyProperty = TextBox.TextProperty
            If Not BindingOperations.IsDataBound(ptextBox, textProp) Then
                Dim b As Binding = New Binding(pproperty)
                b.Source = source
                b.Mode = BindingMode.TwoWay
                b.Path = New PropertyPath(pproperty)
                ptextBox.SetBinding(TextBox.TextProperty, b)
            End If

End Sub

Best regards
Marco

Hello Silvio,

My suggestion is to use FilterDescriptor instead of FieldFilterDescription. FieldFilterDescription is used for our own internal purpose to create filtering drop down.

You can create a FilterDescriptor and bind its value to the TextBox.Text  property. Then you will need to add this FilterDescriptor to the FilterDescriptors property of RadGridView.
