Chart Demo not working

[Stephan]

I am new to Rad Ajax Comntrols and i was looking to put a chart in my program that would show the percentage of entries each sales person has.  My data is in an Access database and I think I need to bind the chart to it in some way.  Anyways I looked at the demo app that gets put on the desktop "http://localhost:8301/radcontrols_aspnetajax/chart/examples/databinding/objects/defaultcs.aspx" when I select data binding->Database I get a stack error.  What was missed on install? 

Cannot open user default database. Login failed.
Login failed for user 'Stephan-PC\Stephan'.

Stephan:

Here's a forum thread that addresses this issue: SQL connection error while running demo .

The "TelerikConnectionString" setting is located in the "Web.config.Net40" located at "C:\Program Files (x86)\Telerik\RadControls for ASP.NET AJAX Q3 2011\Live Demos"

<connectionStrings>
    <add name="NorthwindConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Northwind.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
    <add name="TelerikConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Telerik.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
    <add name="NorthwindConnectionString35" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Northwind.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
    <add name="TelerikConnectionString35" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Telerik.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
    <add name="NorthwindEntities" connectionString="metadata=res://*;provider=System.Data.SqlClient;provider connection string="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Northwind.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient"/>
    <add name="TelerikEntities" connectionString="metadata=res://*;provider=System.Data.SqlClient;provider connection string="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Telerik.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient"/>
    <add name="QSFRatingsConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|QSFRatings.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
<add name="SelfReferencingDbConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|TelerikSelfReferencingDb.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
</connectionStrings>

Alternatively, you can access/run the Chart/Database demo from the Telerik site and view all of the associated code.

Cheers!
