Question

I have a page in asp.net (web forms) that up until now only had one database for data.

So all the controls that require something from the database use a datasource and the same connection string.

<asp:SqlDataSource id="SqlDataSource1" runat="server"
                    ConnectionString="<%$ ConnectionStrings:DefaultConnectionString %>" 
                    ProviderName="System.Data.SqlClient" 
                                        SelectCommand="SELECT ... ">
</asp:SqlDataSource>

Up until now I only needed one connection string since I had only one database but this has changed since I want some users to connect to database A and others to database B

What would be the correct way to go about it? Preferably without many changes…

Answer 1

You can change it programatically after you determine which one you want to use, i.e.

SqlDataSource1.ConnectionString = "whateveryouwant";

It doesn’t have to be set inline in the control.
