Has anyone found a work around for this.

That is raising an event once the date has changed.

C

Resolved this.

private void SetupPage(){

     DependencyPropertyDescriptor selectedDateChangedDescriptor =

             DependencyPropertyDescriptor.FromProperty(DatePicker.SelectedDateProperty, typeof(DatePicker));

     selectedDateChangedDescriptor.AddValueChanged(dpSendDate, new EventHandler(OnSelectedDateChanged));

private void OnSelectedDateChanged(object sender, EventArgs e){

      //Do what you need to do here

Awesome Craig, thank you very much. I had this exact problem.

For info the following works in VB:

    Protected Overrides Sub OnInitialized(ByVal e As EventArgs)

        MyBase.OnInitialized(e)

        Dim dpSourceDescriptor As DependencyPropertyDescriptor = DependencyPropertyDescriptor.FromProperty(Xceed.Wpf.Controls.DatePicker.SelectedDateProperty, GetType(Xceed.Wpf.Controls.DatePicker))

        dpSourceDescriptor.AddValueChanged(Me.xcd_Date, New EventHandler(AddressOf OnSelectedDateChanged))

    End Sub

    Protected Sub OnSelectedDateChanged(ByVal sender As Object, ByVal args As EventArgs)

        TextBox1.Text = xcd_Date.SelectedDate

        MsgBox("Changed")

    End Sub
