Can’t seem to set the DataContext in XAML

[kender_a]

Colleagues,

I’m experimenting with data binding. I wrote a simple test program with only one object representing a person and two TextBoxes bound to its properties (first and last names), which reside in the StackPanel layout. In the beginning, I was assigning the DataContext in the window’s constructor:

base.DataContext = m_objPerson;

That worked.
Then I’ve tried a different approach. Instead of assigning DataContext in code, I would like to assign it in XAML. StackPanel layout has a DataContext property. Shouldn’t it set the DataContext properties for all of the components contained in the layout? I’ve removed the assignment from code and added an assignment in XAML:

<StackPanel DataContext="m_objPerson">

Unfortunately, the text boxes were no longer bound. Could anyone help me find the error?

Cheer,
-Nick
