Solution 1

makes a global Connection in web.config page.. Add this code

<appSettings>
<add key="mas" value="data source=ARSHAD\SQLEXPRESS; initial catalog=ug; integrated security=true;"/>
</appSettings>
<connectionStrings/>

In C# page.. Declare Connection & write it before page load i.e. makes it lobally..

SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["mas"]);

after that use only con (i.e. connection obj) where u need for connection.. by this there is no need to makes connection again & again..

Plz vote me or mark as solution if this is ur solution.

make a static class

C#

class ClsMain
    {
        
        public static SqlConnection Con = null; 

    }

make a fuction to make connection

C#

public static SqlConnection GetConnection(string connectionString)
        {
            SqlConnection connection = new SqlConnection(connectionString);
            connection.Open();           

            return connection;
        }

use this line initialize connection

C#

clsMain.Con=GetConnection("connection string");
