Datasource of Silverlight Teechart

Datasource of Silverlight Teechart

Postby Anil Kumar » Tue Feb 10, 2009 9:35 am

Hi,
I am evaluating TeeChart v4 Silverlight.

What can be the Chartseries Datasource?

I tried to bind Chart Series to ObservableCollection<>, but it doesn't work.


ObservableCollection<Customer> coll = new ObservableCollection<Customer>();
//code to fill the collection.....

Line lineSeries1 = new Line();
tChart1.Series.Add(lineSeries1);
lineSeries1.Title = "line1";
lineSeries1.XValues.DataMember = "Age";
lineSeries1.YValues.DataMember = "Salary";
lineSeries1.DataSource = coll;


Regards,
Priya

Hi Priya,

Have you tried something as Christopher Ireland's example here?

Hi Narcis,

No, I am not trying as Christopher Ireland's example.

I simply want to bind the datasource to Silverlight Teechart.
Since Silverlight does not have ADO.Net, Silverlight Teechart can not be binded to Dataset. That's why I am trying to bind it to ObservableCollection. But the chart doesn't get plotted.

What can be other possible datasources for Silverlight Teechart?

Any feedback would be appreciated.

Regards,
Priya

Sorry, Narcis. I guess there is some confusion.
I already have TeeChart v4 Silverlight beta provided by Steema Sales team. API documentation is not provided with it.
Isn't there way to bind Silverlight Teechart with some datasource? If yes, What are the datasources which can be bound?

Regards,
Priya

Hi Priya,

Yes, but at that thread I was also speaking about v4 Silverlight beta as there's no Silverlight version of TeeChart for .NET v3. v4's beta is the first TeeChart Silverlight version available. Anyway, a new beta has been uploaded at our website which accepts objects of type ObservableCollection<T> for Series DataSource. Here's an example:

Code: Select all
  public partial class Page : UserControl
  {
    public Page()
    {
      InitializeComponent();
      InitializeChart();
    }

    private Steema.TeeChart.Silverlight.Styles.Bar bar;
    private NameList observable;
    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      tChart1.Series.Add(bar = new
Steema.TeeChart.Silverlight.Styles.Bar());

      bar.XValues.DataMember = "DateOfBirth";
      bar.YValues.DataMember = "Height";
      bar.LabelMember = "LastName";
      bar.ColorMember = "FavoriteColor";

      observable = new NameList();
      bar.DataSource = observable;
    }
  }

  public class NameList : ObservableCollection<Person>
  {
    public NameList()
      : base()
    {
      Add(new Person("Willa", "Cather", DateTime.Parse("22/09/1941"), Colors.Red, 171));
      Add(new Person("Isak", "Dinesen", DateTime.Parse("01/07/1964"), Colors.Green, 189));
      Add(new Person("Victor", "Hugo", DateTime.Parse("30/03/1987"), Colors.Blue, 196));
      Add(new Person("Jules", "Verne", DateTime.Parse("14/10/1995"), Colors.Orange, 175));
    }
  }

  public class Person
  {
    private string firstName;
    private string lastName;
    private DateTime dob;
    private Color favorite;
    private int height;

    public Person(string first, string last, DateTime dob, Color favorite, int height)
    {
      this.firstName = first;
      this.lastName = last;
      this.dob = dob;
      this.favorite = favorite;
      this.height = height;
    }

    public string FirstName
    {
      get { return firstName; }
      set { firstName = value; }
    }

    public string LastName
    {
      get { return lastName; }
      set { lastName = value; }
    }

    public DateTime DateOfBirth
    {
      get { return dob; }
      set { dob = value; }
    }

    public Color FavoriteColor
    {
      get { return favorite; }
      set { favorite = value; }
    }

    public int Height
    {
      get { return height; }
      set { height = value; }
    }
  }


I'll send you an e-mail, to your forums contact e-mail address, with the URL to download the version.

Thanks alot, Narcis.
The SilverLight Teechart binding with ObservableCollection is working fine now :D

Can I get beta download for Teechart .NET 4 for WPF as well?
I have WPF Teechart .NET version 3 which does not support ObservableCollection. We are creating controls for Silverlight and WPF whose API going to be same.

Thanks,
Priya

Hi Priya,

Such beta doesn't exist at the present moment. A beta version of the next TeeChart for .NET major upgrade release, will be made available early March.
