WPF Binding To Object Not Working

[=?Utf-8?B?UGhpbCBKb2huc29u?=]

Hello,

My first attempt to bind a 'detail' form to the properties on an object and
the binding is not working.

I have the following grid:

<Grid x:Name="MainGrid">
<StackPanel FlowDirection="LeftToRight">
<TextBlock Foreground="#FFFFFFFF">First name:</TextBlock>
<TextBox Text="{Binding Path=UserName}"></TextBox>
</StackPanel>
</Grid>

And the code behind on the load for the form runs the following... its
definitely executing and the UserName property of _user is set to "Phillip",
but nothing displays in the text box detailed above!

this.MainGrid.DataContext = _user;

Is there some obvious properties or calls I need to set or make to get a
simple binding app like this to work? Or am I missing something else?

Thanks.

I'm no expert on this, but I think you need to specify the object that
has the UserName property in your Binding regardless of the
DataContext. Also, is UserName a DependencyProperty? You should
probably invest in some WPF books to get you started.

Thanks for the response...

I've read a bit about it in Essential Windows Presentation Foundation by
Chris Anderson and I'm also looking at this tutorial....

The only thing different in my code is my object does not currently
implement the INotifyPropertyChanged interface, but in Chris Anderson's book
he says that's optional.

Might try implementing the interface and seeing if it binds... not too
hopeful though. If anybody has any ideas I would be grateful.
