Get control collection from a XAML window

Question

HI all: C# VS 2010 what is the best way to collect the controls Names(X:Name) from a XAML window?

Let's say I have textbox,chkbox,datagrid,radio option and so on... I would like to collect the x:Name of each element

TIA

P.D. I would like to add some security as read-only to some of the textboxes.
