Binding Info usage at run time

Hi

I have a grid view , which columns are mapped to some properties in the ViewModel. At run time , I have to read the information from the grid. For that I am trying to do the following :

1. Read the binding info of the each grid column.

2.Using reflection , I will execute that property of the view Model.

Now thing is that , some properties are like "ViewModel.property1.subproperty" ...

How to execute these kind of properties ??
