  • 參考

定義

命名空間:
System.Windows.Forms
組件:
System.Windows.Forms.dll

取得包含要比較的第二個儲存格的資料列之索引。

public:
 property int RowIndex2 { int get(); };
public int RowIndex2 { get; }
member this.RowIndex2 : int
Public ReadOnly Property RowIndex2 As Integer

屬性值

Int32

包含第二個儲存格的資料列之索引。

範例

下列程式碼範例示範如何在 RowIndex2 多個資料行排序中使用 。 此範例是How to： Customize Sorting in the Windows Forms DataGridView Control中所提供的較大範例的一部分。

private void dataGridView1_SortCompare(object sender,
    DataGridViewSortCompareEventArgs e)
{
    // Try to sort based on the cells in the current column.
    e.SortResult = System.String.Compare(
        e.CellValue1.ToString(), e.CellValue2.ToString());

    // If the cells are equal, sort based on the ID column.
    if (e.SortResult == 0 && e.Column.Name != "ID")
    {
        e.SortResult = System.String.Compare(
            dataGridView1.Rows[e.RowIndex1].Cells["ID"].Value.ToString(),
            dataGridView1.Rows[e.RowIndex2].Cells["ID"].Value.ToString());
    }
    e.Handled = true;
}

Private Sub DataGridView1_SortCompare( _
    ByVal sender As Object, ByVal e As DataGridViewSortCompareEventArgs) _
    Handles DataGridView1.SortCompare

    ' Try to sort based on the contents of the cell in the current column.
    e.SortResult = System.String.Compare(e.CellValue1.ToString(), _
        e.CellValue2.ToString())

    ' If the cells are equal, sort based on the ID column.
    If (e.SortResult = 0) AndAlso Not (e.Column.Name = "ID") Then
        e.SortResult = System.String.Compare( _
            DataGridView1.Rows(e.RowIndex1).Cells("ID").Value.ToString(), _
            DataGridView1.Rows(e.RowIndex2).Cells("ID").Value.ToString())
    End If

    e.Handled = True

End Sub

備註

當根據多個資料行中的資料格值排序資料列時，這個屬性很有用。
