Vb.net 自定义验证程序OnserverValidate调用类函数

我试图在ServerValidate上为自定义验证器调用cetralized类函数，所以我不必在每个页面上都编写它。我该怎么做

提前谢谢

您可以创建一个模块或类，其中包含一个共享函数作为servervalidate函数。您必须手动添加事件的处理程序：

aspx：

可重用验证程序类：

Public NotInheritable Class ValidatorUtil
    Public Shared Sub myFunction(ByVal source As Object, ByVal args As ServerValidateEventArgs)
        'validate here and set IsValid'
        args.IsValid = False
    End Sub

End Class

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
     AddHandler Me.CustomValidator1.ServerValidate, AddressOf ValidatorUtil.myFunction
 End Sub

Public NotInheritable Class ValidatorUtil
    Public Shared Sub myFunction(ByVal source As Object, ByVal args As ServerValidateEventArgs)
        'validate here and set IsValid'
        args.IsValid = False
    End Sub

End Class
