DataGrid Reuse

[Merex]

I have a DataGrid that I will use three different pages. It uses
TemplateColumn's (Item, Edit, and Footer Templates). On one page the
grid is editable, and on the other two I want it read only.

Is there a way to reuse the grid on each page without having to
re-define all of the Template columns in the ASPX file.
Is a user control the way to go?
How about Page.LoadTemplate?

Thanks,
Ross
