Is there a way to make binding happen in a Silverlight control that is created in code?

I'm wanting to print a UserControl that binds to a view model. I create the control in code because if I don't it prints off the edge of the page. Apparently, there is no way to control the size or scale of a printed UIElement without screwing up the element that is on the Silverlight page. So I create the 'UserControl' with the following code in the PrintPage event of a PrintDocument:

    private void OnPrintPage(object sender, PrintPageEventArgs e)
    {
        PurchaseReceipt purchaseReceipt = new PurchaseReceipt();

        purchaseReceipt.DataContext = _receiptData;
        purchaseReceipt.Visibility = System.Windows.Visi开发者_开发百科bility.Visible;

        purchaseReceipt.Margin = new Thickness(25.0);
        purchaseReceipt.Width = e.PrintableArea.Width - 50.0;

        e.PageVisual = purchaseReceipt;
    }

The problem is that binding doesn't work, or doesn't work in time. Is there a way to force an element to bind?
