    <p>I would do that like this: </p> <ol> <li><p>Introduce an interface that will manage the connection strings:</p> <pre><code>public interface IConnectionStringManager { string GetConnectionString(); } </code></pre></li> <li><p>With the implementation that has IConfigurationProfileProvider injected into it:</p> <pre><code>public class ConnectionStringManager : IConnectionStringManager { private readonly IConfigurationProfileProvider&lt;CustomerProfile&gt; _configurationProfileProvider; public ConnectionStringManager(IConfigurationProfileProvider&lt;CustomerProfile&gt; configurationProfileProvider) { _configurationProfileProvider = configurationProfileProvider; } public string GetConnectionString() { return _configurationProfileProvider.GetProfile().CustomerDatabaseConnectionString; } } </code></pre></li> <li><p>Then inject IConnectionStringManager into CustomerDataContext and get the connection string.</p> <pre><code>public CustomerDataContext(IConnectionStringManager connectionStringManager) { var connectionString = connectionStringManager.GetConnectionString(); // pass the connectionString to your context } </code></pre></li> <li><p>And register ConnectionStringManager and CustomerDataContext as usual:</p> <pre><code>builder.RegisterType&lt;ConnectionStringManager&gt;().As&lt;IConnectionStringManager&gt;(); builder.RegisterType&lt;CustomerDataContext&gt;() .As&lt;ICustomerDataContext&gt;() .As&lt;IDbContext&gt;() .InstancePerDependency(); </code></pre></li> </ol> <p>BTW, Take a look at the <a href="http://code.google.com/p/autofac/wiki/MultitenantIntegration" rel="nofollow">Autofac Multitenant Integration</a> which could ease multitenant support.</p>

    1. COThanks Alexandr! Can you show me how I can do step-3 with some code?

    2. COAlso, in my application after user logs in based on his customer-id I will know connection string for his customer database. So, do I need to do these 4 steps after his login button click event? and will that change my db context dynamically on the fly?

    3. CO@rajcool111 Regarding step 3, it depends on your CustomerDataContext implementation. I would go with constructor injection, something like "public CustomerDataContext(IConnectionStringManager connectionStringManager) { var connectionString = connectionStringManager.GetConnectionString();}". Also I updated the answer.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
