使用例

次のサンプルはDisplayMemberPathプロパティとSelectedValuePathプロパティを使ってデータソースをRadioGroupCellTypeに設定する方法を説明します。

C#
Visual Basic

public void SetArraySource()
{
    RadioGroupCellType radio = new RadioGroupCellType();
    radio.ItemsSource = new string[] { "Alice", "Robert", "Ken", "Alen" };
    gcSpreadGrid1[0, 0].CellType = radio;
}

public void SetItemsSource()
{
    RadioGroupCellType radio = new RadioGroupCellType();
    radio.ItemsSource = new NameList();
    radio.DisplayMemberPath = "FirstName";
    radio.SelectedValuePath = "LastName";
    gcSpreadGrid1[0, 0].CellType = radio;
}

public class NameList : ObservableCollection<PersonName>
{
    public NameList()
        : base()
    {
        Add(new PersonName("Alice", "Cather"));
        Add(new PersonName("Robert", "Dinesen"));
        Add(new PersonName("Ken", "Hugo"));
        Add(new PersonName("Alen", "Verne"));
    }
}

public class PersonName
{
    private string firstName;
    private string lastName;

    public PersonName(string first, string last)
    {
        this.firstName = first;
        this.lastName = last;
    }

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

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

Public Sub SetArraySource()
    Dim radio As New RadioGroupCellType()
    radio.ItemsSource = New String() {"Alice", "Robert", "Ken", "Alen"}
    gcSpreadGrid1(0, 0).CellType = radio
End Sub

Public Sub SetItemsSource()
    Dim radio As New RadioGroupCellType()
    radio.ItemsSource = New NameList()
    radio.DisplayMemberPath = "FirstName"
    radio.SelectedValuePath = "LastName"
    gcSpreadGrid1(0, 0).CellType = radio
End Sub

Public Class NameList
    Inherits ObservableCollection(Of PersonName)
    Public Sub New()
        MyBase.New()
        Add(New PersonName("Alice", "Cather"))
        Add(New PersonName("Robert", "Dinesen"))
        Add(New PersonName("Ken", "Hugo"))
        Add(New PersonName("Alen", "Verne"))
    End Sub
End Class

Public Class PersonName
    Private m_firstName As String
    Private m_lastName As String

    Public Sub New(first As String, last As String)
        Me.m_firstName = first
        Me.m_lastName = last
    End Sub

    Public Property FirstName() As String
        Get
            Return m_firstName
        End Get
        Set(value As String)
            m_firstName = value
        End Set
    End Property

    Public Property LastName() As String
        Get
            Return m_lastName
        End Get
        Set(value As String)
            m_lastName = value
