VB.net從后面的代碼禁用CompareValidator

Question

是否可以從VB.net中的代碼后面禁用CompareValidator / RequiredFieldValidator ？

我有3個字段（下拉列表和兩個日期選擇器），並且從下拉列表中選擇了一個月后，我想在datepicker輸入上禁用驗證/必需 。

任何建議，不勝感激！

請注意，您已經嘗試過此方法，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

您可以通過執行類似的操作從code behind啟用或禁用驗證器

CompValidator.Enabled=false

編輯：為DropDownList設置AutoPostBack=true有助於
