c# - 在 TableLayoutPanel Visual Studio 中交换控件

Question

我需要在 TableLayoutPanel 中交换控件。它们在不同的行中。我已经尝试了建议的代码，但无济于事。除了删除所有控件并重新添加之外，还有其他解决方案吗？答案可以使用 C# 或 VB。

Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
    Dim c1 As Control = Me.tlp.GetControlFromPosition(0, 0)
    Dim c2 As Control = Me.tlp.GetControlFromPosition(0, 1)

    If c1 IsNot Nothing And c2 IsNot Nothing Then
        Me.tlp.SetRow(c2, 0)
        Me.tlp.SetRow(c1, 1)
    End If

End Sub

Answer 1

这是在 TableLayoutPanel 中交换控件的代码 - 您有两个选择。

1) 通过引用控件交换:

Private Sub SwapControls(tlp As TableLayoutPanel, ctl1 As Control, ctl2 As Control)
  Dim ctl1pos As TableLayoutPanelCellPosition = tlp.GetPositionFromControl(ctl1)
  tlp.SetCellPosition(ctl1, tlp.GetPositionFromControl(ctl2))
  tlp.SetCellPosition(ctl2, ctl1pos)
End Sub

它不取决于控件在 TableLayoutPanel 中的位置 - 可以是不同的行、列或两者。

示例用法:

SwapControls(TableLayoutPanel1, Button1, Button2)

2) 按列/行索引交换:

Private Sub SwapControls(tlp As TableLayoutPanel, pos1 As TableLayoutPanelCellPosition, pos2 As TableLayoutPanelCellPosition)
  Dim ctl1 As Control = tlp.GetControlFromPosition(pos1.Column, pos1.Row)
  Dim ctl2 As Control = tlp.GetControlFromPosition(pos2.Column, pos2.Row)
  SwapControls(tlp, ctl1, ctl2)
End Sub

示例用法:

SwapControls(TableLayoutPanel1, New TableLayoutPanelCellPosition(0, 0), New TableLayoutPanelCellPosition(1, 0))

解决方案基于 TableLayoutPanel.SetRow MSDN 上的帮助文章及其反编译表示的一些研究。两者都经过测试并被认为有效。
