XtraReports using Entity Framework

created 7 years ago

Hi,

I have a Report that is wired up using the built in Entity Framework and bindings as follows :-

DevExpress.DataAccess.EntityFramework.EFConnectionParameters efConnectionParameters1 = new DevExpress.DataAccess.EntityFramework.EFConnectionParameters();
efConnectionParameters1.Source = typeof( ConnectReportDBContext );

efDataSource1 = new DevExpress.DataAccess.EntityFramework.EFDataSource( efConnectionParameters1 );

I would like to turn on AsNoTracking to help improve performance.

Is this possible?

Thanks,

Daniel.

    Hi Daniel,
    Upon research, we found no way to disable the tracking option for the queries created internally issued by our EFDataSource component. This possibility is only available for EF Core, as it allows handling those settings at the DBContext level:

    C#
    DBContext.ChangeTracker.QueryTrackingBehavior = QueryTrackingBehavior.NoTracking;

    Considering this, we've decided to include this support in future versions of our component. Note that this support will be optional since AsNoTracking() has its own downsides:  Entity Framework merge option not tracking bad performance | StackOverflow. Note that right now there is no day established, but I can say for sure it won't be possible to propagate the required changes to the version you're currently using (15.2). If you're not planning to update any time soon, I'd recommend replacing the EFDataSource component with ObjectDataSource and doing a LINQ query manually: Bind a Report to an Object Data Source
    I hope it helps.

    Regards,
    Yaroslav
