VB.net从后面的代码禁用CompareValidator

Question

是否可以从VB.net中的代码后面禁用CompareValidator / RequiredFieldValidator ？

我有3个字段（下拉列表和两个日期选择器），并且从下拉列表中选择了一个月后，我想在datepicker输入上禁用验证/必需 。

任何建议，不胜感激！

请注意，您已经尝试过此方法，但是它不起作用：

Protected Sub DashbodropardMonthsDropDown_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DashbodropardMonthsDropDown.SelectedIndexChanged
        ' If Month is selected from DD menu
        Dim MonthDD As Integer = DashbodropardMonthsDropDown.SelectedValue

        ' If nothing selected or selected "--select" with value 0
        If MonthDD = 0 Then

            'Validate DatePicker
            CompareValidatorT1.Enabled = True
            RequiredFieldValidator2.Enabled = True
            RequiredFieldValidator1.Enabled = True

        Else

            'Do Not Validate DatePicker
            CompareValidatorT1.Enabled = False
            RequiredFieldValidator2.Enabled = False
            RequiredFieldValidator1.Enabled = False


        End If

    End Sub

您可以通过执行类似的操作从code behind启用或禁用验证器

CompValidator.Enabled=false

编辑：为DropDownList设置AutoPostBack=true有助于
