Can you be more specific? What do you want to store, a customer record into a customer enity. Do you want to use ADO or an ORM

I hope this will help you.

C#

SqlConnection con = new SqlConnection("your connection string");
SqlCommand cmd = new SqlCommand("your select quary", con);
SqlDataAdapter adp = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
if (con.State == ConnectionState.Closed)
    con.Open();
adp.Fill(dt);

if (dt.Rows.Count > 0)
{
   string name=dt.Rows[your row index]["your column name"].toString();
}

Hi
You can use the following.
datatableforQuery=getdatafromdatabase();
session["Keepdata"]=datatableforQuery;

where getdatafromdatabase() is the mathod that retrive the data from DB query("

SQL

select * from customer"

)

this session variable is very intelligent it will cast to datatable automatically.

another ways is use
a)Viewstate
b)Hashtable
c)temp table in sql server

Hope it will help you.

Thanks
