DataGridViewSortCompareEventArgs.RowIndex1 属性
定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
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
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。
