You mean something like this:

Let's say you have two pages:

1. Default.aspx
2. AddUser.aspx

The Default.aspx page will be used display all the users from the database and the AddUser.aspx will be used to insert a user in the database.

The Default.aspx contains a DataGridView to display the users. In the code behind you bind the DataGridView to the Users datatable from a dataset.
In the Page_Load you populate the DataGridView with data.

Now, everytime you view the Default.aspx page you'll have the DataGridView control showing the existent users in the datatable.
