I have a .aspx site.

I have a header that I want on the entire site. So I made it a User Control
..ascx file. In this header, I make one SQL call, so I need to create all the
connection objects, etc.

So I embed that User Control in the .ascx file. No problem.

The problem is I have to make another SQL call in the .aspx file. But it
appears that I can not use the same connection object that I declared in the
..ascx file.

I do not want to create multiple connection object for each page.

Is there a proper way to do this considering the requirements? Maybe use a
code-behind. I only want to create one connection object per page.

Why not? As long as you close each connection after you are done with it, it
will be fine (unless we are talking many many connections).

You can also do some things like have a base page with a connection property
exposed, and then have all your user controls get the current page's
connection via this property.

Behind the scenes, ADO.NET manages a connection pool for you (by default).
It will re-use connections out of this pool or create new ones for you in a
fashion somewhat independent of you creating connection objects in your
code.

The Page object that you get in your ascx is of the aspx's class. You
can expose public methods on it (or declare the base page to derive from an
interface if you need to be generic) and call them. Note however that the
intialisation order is somewhat random, you need to code with this in mind .

However, I would not do that unless I have a significant amount of data
to share (a dataset for instance).
