如果Datagridview中的Data存在，则将checkbox值设置为true，否则为False

Question

我有一个程序，它看起来像这样

我的目标是如果存在某个名称且其值为True或其他为假，我如何将复选框的值设置为true

我有这段代码，但它不能正常工作

    For Each dr As DataGridViewRow In Me.DataGridView1.Rows
                If dr.Cells(0).Value.ToString = "Button2" and dr.Cells(1).Value.ToString = "True" Then checkbox23.checked = True Else checkbox23.checked = False

and so on
.

.
.
.
.
.

.
.
.
            Next
        End Sub

任何帮助都非常感谢TYSM

  Public Function EnableByPermission(ByVal buttonName As String) As Boolean
        Dim Enable As Boolean = False

        ' Look over the Enumerable collection of Rows the one where the
        ' cell for ControlName contains the button name required
        Dim row = DataGridView1.Rows _
                  .Cast(Of DataGridViewRow)() _
                  .FirstOrDefault(Function(x) _
                      x.Cells("ControlName").Value.ToString = buttonName)


        ' If we found it then return the boolean value for the Access column      
        If row IsNot Nothing Then
            Enable = Convert.ToBoolean(row.Cells("Access").Value)
        End If
        Return Enable
    End Function
    Private Sub Form7_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
        CheckBox23.Checked = EnableByPermission("Button2")
    End Sub
