You need a DataSet or DataTable that can be binded with GridView.This code will be added in the Page_Load() of default2.aspx(according to your specification):

C#

string query = "your query";
SqlCommand cmd = new SqlCommand(query, conn); //conn is your SqlConnection
DataTable results = new DataTable();

 try
            {

                SqlDataAdapter adapter = new SqlDataAdapter(command);

                adapter.Fill(results);
            }
catch (Exception ex)
            {
              //handle the error message here
            }

Then to bind Gridview:

C#

GridView.DataSource=results;
GridView.DataBind();

Note I am not using conn.Open(), because the Fill() method will do that, according to msdn reference:http://msdn.microsoft.com/en-us/library/bh8kx08z.aspx[^]

And the issue is?

It does not work like this here.

Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it's not that hard.
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.
Members will be more than happy to help like this.

For now, here are the steps:
1. Create a web application and add the two pages.
2. On page1, place a button and define it's click handler
3. In button click handler, redirect the page on second one.
4. On page2, get the data from DB using ADO.NET (using SQL query)
5. Bind the data retrieved to the grid

Done!
