I have an ASP.NET application with about 20 webforms.

I created Class1.vb, and in this class I have this:

    Public Shared MSSQLCommand As Data.SqlClient.SqlCommand
    Public Shared MSSQLConnection As New Data.SqlClient.SqlConnection

And in all of my webforms, I have this code:
Class1.MSSQLConnection.ConnectionString = ConfigurationManager.ConnectionStrings("DataConnection").ConnectionString

This is causing all kinds of problems, giving errors saying a "connection is string is open" when multiple users access the pages at the same time.

The only other thing I know to do is delcare MSSQLConnection as private on all of my forms.  I'd much rather delcare them once and reference them.  Is there another way I can do this?   I like having code that uses as little repetition as possible...it sems that if I add a
"Private MSSQLConnection as New Data.SqlClient.SqlConnection" at the top of all of my web forms, that I'm being inefficient...or is that the only way to do this?

You generally don't want to leave a connection open for longer than it has to be, and sharing one connection in an ASP.NET application is sure to be troublesome--each request to your page will end up in its own thread; you can end up with synchronization issues. What is the reason you wouldn't want to declare a connection object on each page?

Also, have you considered an n-tier architecture. You can have a "data access layer" which communicates with your database. In this way, you define a contract with your UI and your DAL, and the method names defined by your DAL won't change--which means your UI doesn't have to change if you ever move your backend database to a different platform. You can create connection objects in each method which accesses the database, and you shouldn't encounter synchronization issues.
