使用loginview将对象引用设置为实例错误

问题描述

嗨！我是ASP.NET的新手。我收到此错误：在loginview中访问控件后，对象引用未设置为实例。我好几天了不知道出了什么问题。在这里我的代码：

Hi! I'm new to ASP.NET. I get this error: Object reference not set to an instance after access controls in a loginview. I've here for days. Don't know what's wrong. Here my code:

Protected Overloads Overrides Sub OnInit(ByVal e As EventArgs)
        MyBase.OnInit(e)
        Dim SubmitButton As Button = Gallog.FindControl("SubmitButton")
        SubmitButton.Attributes("onclick") = "return SubmitbButton_click()"

    End Sub

任何帮助将不胜感激。在此先感谢。

Any help will be much appreciated. Thanks in advance.
