Hi,

Delcare all the company database connection strings in web.config like below,

<add name="ConnectionString" connectionstring="Data Source=x.x.x.x ;Initial Catalog=database1;User ID=sa;Password=sa" providername="System.Data.SqlClient" />
<add name="ConnectionString1" connectionstring="Data Source=y.y.y.y;Initial Catalog=database2;User ID=sa;Password=sa" providername="System.Data.SqlClient" />

When your login store the Company name along with user name.

When you are trying to get the connection string, use the following code,

string CompanyName = "Sam";
string conn_str = string.Empty;
if(CompanyName.Equals("Sam"))
ConfigurationSettings.AppSettings.Get("ConnectionString");
else
ConfigurationSettings.AppSettings.Get("ConnectionString1");

SqlConnection conn = new SqlConnection(conn_str);
conn.Open();
