示例

下面的代码示例演示如何在 UserDeletingRow 事件中使用 SelectedRows 属性。 在此示例中，如果集合中包含 SelectedRows 第一行，则取消删除。 此示例是 事件中提供的更大示例的 SelectionChanged 一部分。

private void DataGridView1_UserDeletingRow(object sender,
    DataGridViewRowCancelEventArgs e)
{
    DataGridViewRow startingBalanceRow = DataGridView1.Rows[0];

    // Check if the Starting Balance row is included in the selected rows
    if (DataGridView1.SelectedRows.Contains(startingBalanceRow))
    {
        // Do not allow the user to delete the Starting Balance row.
        MessageBox.Show("Cannot delete Starting Balance row!");

        // Cancel the deletion if the Starting Balance row is included.
        e.Cancel = true;
    }
}

Private Sub UserDeletingRow(ByVal sender As Object, _
    ByVal e As DataGridViewRowCancelEventArgs) _
    Handles DataGridView1.UserDeletingRow

    Dim startingBalanceRow As DataGridViewRow = DataGridView1.Rows(0)

    ' Check if the starting balance row is included in the selected rows
    If DataGridView1.SelectedRows.Contains(startingBalanceRow) Then
        ' Do not allow the user to delete the Starting Balance row.
        MessageBox.Show("Cannot delete Starting Balance row!")

        ' Cancel the deletion if the Starting Balance row is included.
        e.Cancel = True
    End If
End Sub

注解

属性 SelectionMode 必须设置为 FullRowSelect 或 RowHeaderSelect ，才能 SelectedRows 使用所选行填充属性。

此属性包含引用所选内容的只读快照。 如果保留此集合的副本，它可能与用户更改所选内容的实际后续 DataGridView 状态不同。 因此，不应对集合的副本进行操作。

若要以编程方式选择行，请将其 Selected 属性设置为 true。
