Access datacontext of a control's parent's parent

Question

Is there is any way in silverlight to access datacontext of a control's parent's parent. I have a user control bound to a viewmodel. User control contains a pivot control bound to one of viewmodel's property. So the pivot control item's datacontext is that property. Now i need to bind that pivot control item to on of usercontrol's datacontext's property(Which is an ICommand). But this property is not available to the pivot control item . In WPF i can achieve this by using RelativeSource={RelativeSource AncestorType={x:Type Grid},AncestorLevel=1}. But AncestorType is not avialble in silverlight.
Thanks in advance and sorry for the long question.

You can't use AncestorType in Windows Phone 7 Development =( It's not supported by the platform.

This solution works on Silverlight 5 (SL5)

Well I'm an AncestorType fan. Remove innecesary code

{x:Type Grid}

Try this line of code on your XAML:

XML

RelativeSource={RelativeSource AncestorType=Grid, AncestorLevel=1}

Hope it helps =)

I use AncestorType on Silverlight. What version of Silverlight are you using?

I use version 4.

May be doesn't work on SL4. How about upgrade to SL5? Let me try this on SL4. What about get your desired control via code behind? Or you needed only on xaml?

It is a windows phone 7 application, so i cannot use SL5.I have already done this using code behind. But just wondering if it can be done by using xaml only
