範例

以下程式碼範例示範了在 CellValue1 多欄排序中的應用。 此範例是《 如何：在 Windows 表單 DataGridView 控制項中自訂排序》中提供較大範例的一部分。

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
