    Hi Vagelis Kretsimos,

    Sometimes this error is caused because a previous install of SQL Express has left files. Try to reinstall SQL Express. If this doesn’t help, could you give us more information about how to reproduce this error?

    I'm getting the same problem trying to run any of the Grid examples. I previously had SQLExpress installed, does the install of RadControls install another instance somewhere? I'm using the connection string as provided in the web.config file:     <add name="TelerikConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Telerik.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>

    Can i attach Telerik.mdf in my installed SQLExpress and connect to that? I'd rathe r not uninstall my SQLExpres.

    Hi BB,

    In order to proceed with the troubleshooting, we need to know the exact version of RadControls you are running and whether you are using them under Sitefinity. Also we would need elaboration on your network environment as well as the exact exception you are receiving.

    Thank you for your assistance in advance.
