Solution 1

Define two ConnectionStrings in web.config file, one for localhost and other for that external database.

Now, while doing database operations, just initialize the SqlConnection class with localhost first and execute the required command. Then initialize the same SqlConnection class or another with the external database ConnectionString and execute the command.

<connectionstrings>
<add name="conn" connectionstring="Data Source=PC;Initial Catalog=demo1;User ID=sa;Password=itpaper">
<add name="conn_2" connectionstring="Data Source=PC;Initial Catalog=demo2;User ID=sa;Password=***">

<connectionstrings>
<add name="conn" connectionstring="Data Source=PC;Initial Catalog=demo1;User ID=sa;Password=****">

if i add these both connection string in web.config then i m getting this below error
Error 2 Sections must only appear once per config file. See the help topic <location> for exceptions. C:\Documents and Settings\User\My Documents\Visual Studio 2008\WebSites\WebSite20\Web.config 32

<connectionstrings>
<add name="conn" connectionstring="Data Source=PC;Initial Catalog=demo1;User ID=sa;Password=itpaper"></add>
<add name="conn_2" connectionstring="Data Source=PC;Initial Catalog=demo2;User ID=sa;Password=***"></add>
<add name="conn_3" connectionstring="Data Source=PC;Initial Catalog=demo1;User ID=sa;Password=****"></add>
</connectionstrings>

<connectionstrings>
<add name="conn" connectionstring="Data Source=PC;Initial Catalog=demo1;User ID=sa;Password=****">

</connectionstrings>

You should not add another ConnectionString tag, instead add new ConnectionString inside the existing tags.
According to the error, it says you can't have same tags many times.

So, correct it. It will work then.
