ComboBox ControlTemplate Question

Hi,

I'm creating my own ComboBox ControlTemplate based on

http://msdn2.microsoft.com/en-us/library/ms752094.aspx

and I'm having a problem with the selected text that goes out of the combo box.

I have already try to put the

Width="{TemplateBinding ActualWidth}"

in the textBox but doesn't seem to work.

Can anyone help me?

Thanks in advance.

Here is the ControlTemplate:
