Hello, I receive a lot of these: Error @ URI: /Category.aspx?CategoryID=3 InvalidOperationException: 'The ConnectionString property has not been initialized.' at System.Data.SqlClient.SqlConnection.PermissionDemand() at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.SqlClient.SqlConnection.Open() at FestaExpress.Data.SqlServer.DataSetSessionsTableAdapters.TempShoppingCartTableAdapter.CountUserOrders(Guid cookieID) in E:\usr\jan\My Documents\Visual Studio 2005\Projects\Festaexpress\FestaExpress.Data.SqlServer\DataSetSessions.Designer.cs:line 1083 at ShoppingCartHelper.GetItemCount(Guid cookieID) at FestaExpress.Web.Site.ShoppingCart.GetItemCount() GetItemCount() is a method that returns the result from a scalar sql query to sqlserver2005 from a dataset/tableadapter. The dataset is in an external dll, I use from a static method in the web site's app_code folder. There are many different Query/Methods in this Dataadapter, using the same connection properties and never fail. When inspecting the (generated) code I do not see anything suspicious there. And of course here on my development machines, this exception has never happened. Anyone any ideas? Thanks, Jan
