如何在datagridview中禁用或隐藏按钮 [英] How to disable or hide button in datagridview

问题描述

您好我想隐藏或禁用我的第3列中的按钮，我打算每次单击时添加行。混乱是，以前的按钮是活动的，可以添加行。我怎样才能将按钮放在最后一排？





有谁可以帮我这个？ TIA。



我的尝试：

 私有  Sub  dgAppliances_CellContentClick（发件人 As  对象，e  As  DataGridViewCellEventArgs）句柄 dgAppliances.CellContentClick 
 
 如果 e.ColumnIndex<>  2  然后 
 退出 < span class =code-keyword> Sub  
  Else  
 如果 我 .dgAppliances.RowCount =  20  然后 
 MsgBox（ 最多只有20个设备。）
 < span class =code-keyword> Else  
 dgvAppsRowNo + =  1  
 我 .dgAppliances.Rows.Add（）
 我 .dgAppliances.Rows（dgvAppsRowNo）.Cells（ 0 ）。值= dgvAppsRowNo +  1  
 
  Dim  cell  As  DataGridViewButtonCell = dgAppliances.Rows（dgvAppsRowNo）.Cells（ 2 ）
 cell.Value =  New  DataGridTextBoxColumn（）
 cell。 ReadOnly  =  True  
 结束 如果 
 结束 如果 
 
 结束  Sub

Hi I want to Hide or Disable the button in my 3rd column which I intend to add row every time I click it. The mess is, the previous buttons are active and can add row. How can I place the button only in the last row?


Can anyone help me about this? TIA.

What I have tried:

Private Sub dgAppliances_CellContentClick(sender As Object, e As DataGridViewCellEventArgs) Handles dgAppliances.CellContentClick

    If e.ColumnIndex <> 2 Then
        Exit Sub
    Else
        If Me.dgAppliances.RowCount = 20 Then
            MsgBox("Maximum of 20 appliances only.")
        Else
            dgvAppsRowNo += 1
            Me.dgAppliances.Rows.Add()
            Me.dgAppliances.Rows(dgvAppsRowNo).Cells(0).Value = dgvAppsRowNo + 1

            Dim cell As DataGridViewButtonCell = dgAppliances.Rows(dgvAppsRowNo).Cells(2)
            cell.Value = New DataGridTextBoxColumn()
            cell.ReadOnly = True
        End If
    End If

End Sub
