Hi,

   I need to create a WPF UserControl (or Control) that has two parts: a header with a Title and a grid right above it. The glitch is: I need to have access to this grid. I need to paste components in this grid. The component works right a Window with a header.

   My idea is create a constant part of the component (the header - the Title is a property) and variable part of it (the grid).

   Is is possible? How?
