HTML

<connectionstrings>
   <add name="connection1" providername="System.Data.SqlClient" connectionstring="Data Source=ServerName;Initial Catalog=Database1;User ID=sa;Password=***" />

 <add name="connection2" providername="System.Data.SqlClient" connectionstring="Data Source=PC1-PC\PC1SQL;Initial Catalog=Database2;User ID=sa;Password=***" />
 </connectionstrings>

CS page.. 1) First Dropdown.(ID="ddl1")

C#

protected void ddl1_SelectedIndexChanged(object sender, EventArgs e)
       {
           SqlConnection cn=new SqlConnection(ConfigurationManager.ConnectionStrings["Connection1"].ConnectionString)
       }

CS page.. 2) Second Dropdown.(ID="ddl2")

C#

protected void ddl2_SelectedIndexChanged(object sender, EventArgs e)
      {
          SqlConnection cn=new SqlConnection(ConfigurationManager.ConnectionStrings["Connection2"].ConnectionString)
      }
