DataGridViewCheckBoxCell关于何时分配其值的问题

我使用这个函数来查看DataGridViewCheckBoxCell值的所有特定列是否都为True。但是,它失败了,因为它似乎认为当前值是错误的。我在_CellContentClick事件中运行此代码,在将值分配给单元格后,是否还有其他地方可以运行此代码?

Private Function AllTasksAreCompleted() As Boolean

    Dim result As Boolean = True

    For Each dgvRow As DataGridViewRow In Me.gridTasks.Rows

        Dim tempCBcell As DataGridViewCheckBoxCell = GetCheckBoxCell(dgvRow, "colCompleted")
        If Not tempCBcell.Value.ToString = "True" Then
            result = False
            Return result
        End If

    Next

    Return result
