Body
I have had a problem where it appeared as though the second execution of a stored procedure was being ignored. The first time I call my stored procedure it found 20 records and extracted information for the date range August 2009. The first line was meter id 233 with a data value 200 I then called the stored procedure and 20 records were also returned. This time meter id 233 had a data value of 300. Linq is detecting that meterid 233 already exists in the context and so doesnt update I am sure this is something to do with ObjectTrackingEnabled but this does not seem to be available for me to set to false? I didnt write the context code so I dont really know how it all works, but I have noticed that it seems to inherit from ObjectDataContext This was generate using Entity Framework and VS 2008 namespace DataServiceDAL { <pre><code>/// <summary> /// There are no comments for dbChildDataContext in the schema. /// </summary> public partial class dbChildDataContext : global::System.Data.Objects.ObjectContext { /// <summary> /// Initializes a new dbChildDataContext object using the connection string found in the 'dbChildDataContext' section of the application configuration file. /// </summary> public dbChildDataContext() : base("name=dbChildDataContext", "dbChildDataContext") { this.OnContextCreated(); } /// <summary> /// Initialize a new dbChildDataContext object. /// </summary> public dbChildDataContext(string connectionString) : base(connectionString, "dbChildDataContext") { this.OnContextCreated(); } /// <summary> /// Initialize a new dbChildDataContext object. /// </summary> public dbChildDataContext(global::System.Data.EntityClient.EntityConnection connection) : base(connection, "dbChildDataContext") { this.OnContextCreated(); } partial void OnContextCreated(); </code></pre> .............. } I use the following linq to extract the data <pre><code> public static List<MeterTotalConsumpRecord> GetTotalAllTimesConsumption(DateTime dtStart, DateTime dtEnd, EUtilityGroup ug, int nMeterSelectionType, int nCustomerID, int nUserID, string strSelection, bool bClosedLocations, bool bDisposedLocations) { dbChildDataContext db = DBManager.ChildDataConext(nCustomerID); var tbl = from t in db.GetTotalConsumptionByMeter(dtStart, dtEnd, (int) ug, nMeterSelectionType, nCustomerID, nUserID, strSelection, bClosedLocations, bDisposedLocations, 1) select t; return tbl.ToList(); } </code></pre> I need a way of clearing this cache out so that the objects are updated properly or I need a way of refreshing the objects Can anyone help? Cheers Paul

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.
