How do I get the key of the currently loaded item in a FormView from a separate user control?
<p>I have a FormView from which another user control is launched.</p>

<p>The FormView loads an "order" from the database.
The UserControl contains a form to insert line items for this order.</p>

<p>When inserting a line item, I need the order ID to associate the line items to the order.</p>

<p>But since the child control is a separate user control, the FormView is not visible and inaccessible.  Does anyone know how I can go about getting the FormViews key value from a different user control?</p>

<p>Using a session or cookie is out of the question unfortunately.</p>

<p>Thanks
Kevin</p>
