DataGridViewSortCompareEventArgs.Column 属性

  • 参考

定义

命名空间:
System.Windows.Forms
程序集:
System.Windows.Forms.dll

获取正在排序的列。

public:
 property System::Windows::Forms::DataGridViewColumn ^ Column { System::Windows::Forms::DataGridViewColumn ^ get(); };
public System.Windows.Forms.DataGridViewColumn Column { get; }
member this.Column : System.Windows.Forms.DataGridViewColumn
Public ReadOnly Property Column As DataGridViewColumn

属性值

DataGridViewColumn

要排序的 DataGridViewColumn。

示例

下面的代码示例演示如何 Column 在多列排序中使用。 在此示例中，ID 列用于确定在排序列中存在相同值时的最终顺序，因此，如果 ID 列中存在重复值，则不会执行其他排序。 此示例是 How to： Customize Sorting in the Windows 窗体 DataGridView Control 中提供的较大示例的一部分。

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
