Binding to MS SQL using EntityFramework 6

hello,

I'm trying to bind scheduler to MS SQL database using EntityFramework 6 and Code First approach. I did it partly but I have a big problem with saving exceptions of recurring appointment.

First of all, I can't find any sample of such (it would seem) common scenario where recurring appointment's exceptional occurrences are stored in database using EntityFramework 6. I would be very grateful if someone could show me such an example because Telerik documentation sample doesn't work.

I have very simple code where I configure RadScheduler, SchedulerBindingDataSource and mapping between entities and scheduler fields. I'm pretty sure my Code First entity model and database tables and relations are correct. Despite this, I'm not able to store in database exceptions of recurring appointments. Recurring appointments with removed occurrences are properly stored and removed dates are saved in recurrence rule of appointment. But occurrences with exceptional time or duration are not saved at all.

Please, help me.

This is my appointment entity with self reference for exceptions:

01.[Table("App")]

02.public class App

03.{

04. public App()

05. {

06. this.Resources = new HashSet<Res>();

07. this.Exceptions = new HashSet<App>();

08. }

09.

10. [Key]

11. [DatabaseGenerated(DatabaseGeneratedOption.None)]

12. public Guid Id { get; set; }

13.

14. [Required(AllowEmptyStrings = false)]

15. [StringLength(255)]

16. public string Summary { get; set; }

17.

18. public DateTime Start { get; set; }

19.

20. public DateTime End { get; set; }

21.

22. public string RecurrenceRule { get; set; }

23.

24. public bool Visible { get; set; }

25.

26. [ForeignKey("MasterEvent")]

27. public Guid? MasterEventID { get; set; }

28.

29.

30. public virtual App MasterEvent { get; set; }

31.

32. public virtual ICollection<App> Exceptions { get; set; }

33.

34. public virtual ICollection<Res> Resources { get; set; }

35.}

and my configuration of relations:

01.protected override void OnModelCreating(DbModelBuilder modelBuilder)

02.{

03. base.OnModelCreating(modelBuilder);

04.

05. modelBuilder.Entity<App>()

06. .HasMany(t => t.Resources)

07. .WithMany(t => t.Apps)

08. .Map(m => {

09. m.ToTable("AppRes");

10. m.MapLeftKey("AppId");

11. m.MapRightKey("ResId");

12. });

13.

14. modelBuilder.Entity<App>()

15. .HasOptional(t => t.MasterEvent)

16. .WithMany(t => t.Exceptions)

17. .HasForeignKey(t => t.MasterEventID)

18. .WillCascadeOnDelete(true);

19.}

and mapping:

01.var appointmentMappingInfo = new AppointmentMappingInfo()

02.{

03. UniqueId = "Id",

04. Start = "Start",

05. End = "End",

06. Summary = "Summary",

07. RecurrenceRule = "RecurrenceRule",

08. Exceptions = "Exceptions",

09. MasterEventId = "MasterEventID",

10. Resources = "Resources",

11. ResourceId = "Id",

12. Visible = "Visible"

13.};

Too many assemblies included?

Program uses spell check and autocomplete on a radtextbox control.

In order to use ILMerge, I have:

Telerik.WinControls.RadTypeResolver.Instance.ResolveTypesInCurrentAssembly = True

Near top of main form.

References in Solution Explorer show:

Telerik.WinControls

Telerik.WinControls.SpellChecker

Telerik.WinControls.UI

Telerik.WinControls.Design

However, when I build the program, I find just about every major Telerik assembly dll, From PdfView, to RadWebCam.
I've searched the entire solution, and can't figure out where all those references are coming from.

Where did I go wrong?

Remove the space of the StartButtonImage

Hi

Is there a way to remove the startButtonImage, respectively the tabs start at the left?

If I set:

this.radRibbonBar1.RibbonBarElement.ApplicationButtonElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

The button is gone but the space is still here.

I also tried:

this.radRibbonBar1.StartButtonImage = null;

this.radRibbonBar1.StartMenuWidth = 0;

but the space is always here.

Thank you in Advance

Kind Regards,

Dominik

An application can have multiples RadGridView and the default scroll bars doesn't match with the theme selected.

An example will be useful.
