[Solved] How to bind more than one collection to just one RadChart declaratively?

[Przemyslaw]

Hi,

Let's say that I have two collections in my ViewModel layer:

ObservableCollection<DayEntry> Logins;
ObservableCollection<DayEntry> Deposits;

where:

public class DayEntry {
   public DateTime day { get; set; }
   public int value { get; set; }
}

Now, I would like to bind both of these collections to just one RadChart as two Data Series declaratively with XAML.

I would like to avoid creating a third, composite collection called something like LoginsAndDeposits that would combine both data sources:

public class DayEntry {
    public DateTime day {get; set;}
    public int loginValue { get; set; }
    public int depositsValue { get; set; }
}

Is that possible, and if yes, how?

regards, Przemek

Hi Przemyslaw,

I'm afraid you will need to nest your collections into a composite one that will serve as items source for the chart control.
