Step 2 of 3: Adding Content to the C1OrgChart Control

In the previous step you created a WPF or Silverlight application and added the C1OrgChart control to your project. In this step you'll add content to the C1OrgChart control. To customize your project and add content to the C1OrgChart control in your application, complete the following steps:

  1. In the Solution Explorer, right-click the MainWindow.xaml and MainPage.xaml file and select View Code. The code file will open.

  2. Edit the code file so that it appears similar to the following:

    Partial Public Class MainWindow
    Inherits Window
    Public Sub New()
        InitializeComponent()
        CreateData()
    End Sub
    Private Sub Button_Click(sender As Object, e As RoutedEventArgs)
        CreateData()
    End Sub
    Private Sub CheckBox_Click(sender As Object, e As RoutedEventArgs)
        _orgChart.Orientation = If(DirectCast(sender, CheckBox).IsChecked.Value, Orientation.Horizontal, Orientation.Vertical)
    End Sub
    Private Sub CreateData()
        Dim p = Data.Person.CreatePerson(10)
        _tbTotal.Text = String.Format(" ({0} items total)", p.TotalCount)
        _orgChart.Header = p
    End Sub
End Class
Public Class PersonTemplateSelector
    Inherits DataTemplateSelector
    Public Overrides Function SelectTemplate(item As Object, container As DependencyObject) As DataTemplate
        Dim p = TryCast(item, Data.Person)
        Dim e = TryCast(container, FrameworkElement)
        Return If(p.Position.IndexOf("Director") > -1, TryCast(e.Resources("_tplDirector"), DataTemplate), TryCast(e.Resources("_tplOther"), DataTemplate))
    End Function
End Class

    namespace QuickStart
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            CreateData();
        }
        void Button_Click(object sender, RoutedEventArgs e)
        {
            CreateData();
        }
        void CheckBox_Click(object sender, RoutedEventArgs e)
        {
            _orgChart.Orientation = ((CheckBox)sender).IsChecked.Value
                ? Orientation.Horizontal
                : Orientation.Vertical;
        }
        void CreateData()
        {
            var p = Data.Person.CreatePerson(10);
            _tbTotal.Text = string.Format(" ({0} items total)", p.TotalCount);
            _orgChart.Header = p;
        }
    }
    public class PersonTemplateSelector : DataTemplateSelector
    {
        public override DataTemplate SelectTemplate(object item, DependencyObject container)
        {
            var p = item as Data.Person;
            var e = container as FrameworkElement;
            return p.Position.IndexOf("Director") > -1
                ? e.Resources["_tplDirector"] as DataTemplate
                : e.Resources["_tplOther"] as DataTemplate;
        }
    }
}

  3. Navigate to the Solution Explorer, right-click the project name, and select Add │ New Item. In the Add New Item dialog box, locate the Code File template, name it "EnumerationExtension", and click Add.

    The new code file will open. Note that this code file is also included with the sample, if you choose you can simply add that file.

  4. Add the following code to the EnumerationExtension code file :

    Imports System.Windows
Imports System.Windows.Controls
Imports System.Windows.Markup
Imports System.Reflection
Imports System.Collections.Generic
Namespace Util
    Public Class EnumerationExtension
        Inherits MarkupExtension
        Public Property EnumType() As Type
            Get
                Return m_EnumType
            End Get
            Set(value As Type)
                m_EnumType = Value
            End Set
        End Property
        Private m_EnumType As Type
        Public Overrides Function ProvideValue(serviceProvider As IServiceProvider) As Object
            Dim list = New List(Of Object)()
            For Each value In EnumType.GetFields(BindingFlags.[Public] Or BindingFlags.[Static])
                list.Add(value.GetValue(Nothing))
            Next
            Return list
        End Function
    End Class
End Namespace

    using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Markup;
using System.Reflection;
using System.Collections.Generic;
namespace Util
{
    public class EnumerationExtension : MarkupExtension
    {
        public Type EnumType { get; set; }
        public override object ProvideValue(IServiceProvider serviceProvider)
        {
            var list = new List<object>();
            foreach (var value in EnumType.GetFields(BindingFlags.Public | BindingFlags.Static))
            {
                list.Add(value.GetValue(null));
            }
            return list;
        }
    }
}

    This code allows you to bind the ComboBox controls to enumeration values so at run time you can choose a bound value to set.

  5. Navigate to the Solution Explorer, right-click the project name, and select Add │ New Item. In the Add New Item dialog box, locate the Code File template, name it "Person", and click Add.

    The new code file will open. Note that this code file is also included with the sample, if you choose you can simply add that file.

  6. Add the following code to the Person code file:

    Imports System.Collections
Imports System.Collections.Generic
Imports System.Collections.ObjectModel
Namespace Data
    Public Class Person
        Private _list As New ObservableCollection(Of Person)()
#Region "** object model"
        Public Property Name() As String
            Get
                Return m_Name
            End Get
            Set(value As String)
                m_Name = Value
            End Set
        End Property
        Private m_Name As String
        Public Property Position() As String
            Get
                Return m_Position
            End Get
            Set(value As String)
                m_Position = Value
            End Set
        End Property
        Private m_Position As String
        Public Property Notes() As String
            Get
                Return m_Notes
            End Get
            Set(value As String)
                m_Notes = Value
            End Set
        End Property
        Private m_Notes As String
        Public ReadOnly Property Subordinates() As IList(Of Person)
            Get
                Return _list
            End Get
        End Property
        Public ReadOnly Property TotalCount() As Integer
            Get
                Dim count = 1
                For Each p In Subordinates
                    count += p.TotalCount
                Next
                Return count
            End Get
        End Property
        Public Overrides Function ToString() As String

}

    This code creates a simple class with a recursive ObservableCollection for items to be displayed in C1OrgChart and creates a method to build a simple organization chart. Note that the C1OrgChart control's default template uses the ToString method to dictate what text is displayed. You will need to override this method (as in the above code) if you're not using a DataTemplate (if you are using a DataTemplate, you can just set your bindings in that and ignore the ToString).

In this step you added content to the C1OrgChart control. In the next step you'll view some of the run-time interactions possible in the control.
