Question

是否可以从VB.net中的代码中禁用CompareValidator / RequiredFieldValidator？

我有3个字段（下拉列表和两个日期选择器），从下拉列表中选择一个月后我想禁用datepicker输入上的验证/必需。

任何建议都非常感谢！

请注意已经尝试过这个，但它不起作用：

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

您可以通过执行此类操作

来启用或禁用code behind的验证程序

CompValidator.Enabled=false

修改为AutoPostBack=true帮助设置DropDownList

VB.net从后面的代码中禁用CompareValidator
