Instead of voting negative this question, answer to tell me what's wrong!

I want to set the Button Content in a label in the custom control, because when I use it, the Content property is not visible and the button is empty (no text).

<Button x:Class="WpfApplication1.UserControl1"

</Button.Template>

The button is based on Adobe CS5 suite on dialog forms, because a lot of code.
