EKG signal using RadChartView

Hello,

The sample 955167-RadChartViewLiveData shows a way to display Live Data using the RadChartView. In this scenario the data points moves from right to left.

I'm looking for show an EKG signal (of one channel) using the RadChartView control. The required features are:

When new data point arrived, it must be added without moving all the points. Just deleted the point in the right side of last point added.
A "white box" after the last point must be showed, to indicate progress. The EKG chart attached shows a degrade which is not required.

Please, may I know a suggested approach to obtain similar results?

Thanks

Conditional Formatting Rules Manager

Hi,

We have used a Telerik RadGridView in our Windows Application.

On specific form user has a option to right mouse click and open conditional formatting

then user gets a popup window of Conditional Formatting Rules Manager.

In that Rules Manager window - we can see some properties under Format section such as CellBackColor and RowBackColor.

for these very particular options CellBackColor and RowBackColor we have set some standard color from code and want to keep it as a standard

thus want to prevent user to go and edit these properties and change the color to something else.

So is it possible to completely disable to edit/hide these options (CellBackColor and RowBackColor) from code, so end user could not change it ?

Please find attached image of Rules Manager.

Add image in the page after a table

I would like from code to insert a table in text, and then insert an image in the very first next page. So I insert a table, then insert a section break, a then insert an image. But it may happen that the table is already at the end of the page, and the section break would spill to the next page, which would result in the image being on the third page with the page in the middle being completely empty. Can I prevent this from happening? The user will be able to edit the text, add lines before the table, and so cause the empty page even if it wasn't there before my insert. The user will not be able to edit the table or anything else after it.

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.};
