DataGridViewSortCompareEventArgs.RowIndex1 属性

  • 参考

定义

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

获取包含要比较的第一个单元格的行的索引。

public:
 property int RowIndex1 { int get(); };
public int RowIndex1 { get; }
member this.RowIndex1 : int
Public ReadOnly Property RowIndex1 As Integer

属性值

Int32

包含第二个单元格的行的索引。

示例

下面的代码示例演示如何 RowIndex1 在多列排序中使用。 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

注解

当基于多个列中的单元格值对行进行排序时，此属性非常有用。
