如何在DataGridView中克隆和删除未选择的行？

Question

我需要以编程方式删除DataGridView中除选定行之外的所有行。首先，我需要只从 CtrlDataGridView1 中选择行并将它们放到 dgv 。我试过这个

Public ReadOnly Property CtrlDataGridView1Filtered() As DataGridView
    Get
        Dim dgv As New DataGridView
        dgv = CtrlDataGridView1

        For Each dr As DataGridViewRow In CtrlDataGridView1.Rows
            If Not dr.Selected Then
                dgv.Rows.Remove(dr)
            End If
        Next
        Return dgv
    End Get
End Property

但不行，因为删除了CtrlDataGridView1的行。但是我只需要删除dgv的行。

我该怎么办？怎么解决这个问题？

您可以克隆DataGridView，然后将所需的行复制到其中，例如

'CLONE COLUMNS ONLY'
Dim dgv As New DataGridView
For Each dgvCol As DataGridViewColumn In CtrlDataGridView1.Columns
    dgv.Columns.Add(New DataGridViewColumn(dgvCol.CellTemplate))
Next

'COPY SELECTED / UNSELECTED ROWS AS PER YOUR REQUIREMENT'
For Each dr As DataGridViewRow In CtrlDataGridView1.Rows
    If dr.Selected Then
    'OR If Not dr.Selected Then'
        dgv.Rows.Add(dr.Clone)
    End If
Next
