使用例

次のサンプルは ComboBoxCellType に ContentPath および SelectedValuePath を使用してデータソースを設定する方法を説明します。

C#
Visual Basic

public void SingleColumnBinding()
{
    ComboBoxCellType combo = new ComboBoxCellType();
    combo.ItemsSource = new string[] {"Alice","Robert","Ken","Alen" };
    gcSpreadGrid1[0, 0].CellType = combo;
}
public void MultipleColumnsBinding()
{
    ComboBoxCellType combo = new ComboBoxCellType();
    combo.UseMultipleColumn = true;
    combo.DropDownWidth = 150;
    combo.ContentPath = "FirstName";
    combo.SelectedValuePath = "LastName";
    combo.ItemsSource = new NameList();
    gcSpreadGrid1[0, 0].CellType = combo;
}

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 SingleColumnBinding()
    Dim combo As New ComboBoxCellType()
    combo.ItemsSource = New String() {"Alice", "Robert", "Ken", "Alen"}
    gcSpreadGrid1(0, 0).CellType = combo
End Sub
Public Sub MultipleColumnsBinding()
    Dim combo As New ComboBoxCellType()
    combo.UseMultipleColumn = True
    combo.DropDownWidth = 150
    combo.ContentPath = "FirstName"
    combo.ItemsSource = New NameList()
    gcSpreadGrid1(0, 0).CellType = combo
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
