DataGridViewColumn.ValueType 속성

정의

네임스페이스:

System.Windows.Forms

어셈블리:

System.Windows.Forms.dll

열의 셀 값에 대한 데이터 형식을 가져오거나 설정합니다.

public:
 property Type ^ ValueType { Type ^ get(); void set(Type ^ value); };

[System.ComponentModel.Browsable(false)]
public Type ValueType { get; set; }

[<System.ComponentModel.Browsable(false)>]
member this.ValueType : Type with get, set

Public Property ValueType As Type

속성 값

Type

열의 셀에 저장되는 값의 런타임 클래스를 설명하는 Type입니다.

특성

BrowsableAttribute

예제

다음 코드 예제에서는 값을 포함 하는 초기화 DataGridViewComboBoxColumn 에서 속성을 사용 ValueType 하는 방법을 보여 줍니다Color.

private DataGridView dataGridView1 = new DataGridView();

private void AddColorColumn()
{
    DataGridViewComboBoxColumn comboBoxColumn =
        new DataGridViewComboBoxColumn();
    comboBoxColumn.Items.AddRange(
        Color.Red, Color.Yellow, Color.Green, Color.Blue);
    comboBoxColumn.ValueType = typeof(Color);
    dataGridView1.Columns.Add(comboBoxColumn);
    dataGridView1.EditingControlShowing +=
        new DataGridViewEditingControlShowingEventHandler(
        dataGridView1_EditingControlShowing);
}

private void dataGridView1_EditingControlShowing(object sender,
    DataGridViewEditingControlShowingEventArgs e)
{
    ComboBox combo = e.Control as ComboBox;
    if (combo != null)
    {
        // Remove an existing event-handler, if present, to avoid 
        // adding multiple handlers when the editing control is reused.
        combo.SelectedIndexChanged -=
            new EventHandler(ComboBox_SelectedIndexChanged);

        // Add the event handler. 
        combo.SelectedIndexChanged +=
            new EventHandler(ComboBox_SelectedIndexChanged);
    }
}

private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
    ((ComboBox)sender).BackColor = (Color)((ComboBox)sender).SelectedItem;
}

Private WithEvents dataGridView1 As New DataGridView()

Private Sub AddColorColumn()

    Dim comboBoxColumn As New DataGridViewComboBoxColumn()
    comboBoxColumn.Items.AddRange( _
        Color.Red, Color.Yellow, Color.Green, Color.Blue)
    comboBoxColumn.ValueType = GetType(Color)
    dataGridView1.Columns.Add(comboBoxColumn)

End Sub

Private Sub dataGridView1_EditingControlShowing(ByVal sender As Object, _
    ByVal e As DataGridViewEditingControlShowingEventArgs) _
    Handles dataGridView1.EditingControlShowing

    Dim combo As ComboBox = CType(e.Control, ComboBox)
    If (combo IsNot Nothing) Then

        ' Remove an existing event-handler, if present, to avoid 
        ' adding multiple handlers when the editing control is reused.
        RemoveHandler combo.SelectedIndexChanged, _
            New EventHandler(AddressOf ComboBox_SelectedIndexChanged)

        ' Add the event handler. 
        AddHandler combo.SelectedIndexChanged, _
            New EventHandler(AddressOf ComboBox_SelectedIndexChanged)

    End If

End Sub

Private Sub ComboBox_SelectedIndexChanged( _
    ByVal sender As Object, ByVal e As EventArgs)

    Dim comboBox1 As ComboBox = CType(sender, ComboBox)
    comboBox1.BackColor = _
        CType(CType(sender, ComboBox).SelectedItem, Color)

End Sub

설명
