Javascript调用VB回发函数导致意外调用错误

javascript asp.net ajax vb.net

Javascript调用VB回发函数导致意外调用错误,javascript,asp.net,ajax,vb.net,modalpopupextender,Javascript,Asp.net,Ajax,Vb.net,Modalpopupextender,下面是VB代码： Dim button As New Button Dim xpanel As New Panel button.Text = "Submit" button.ID = "button" button.Height = "40" button.Attributes.Add("Autopostback", "true") button.Attributes.Add("Onclick", "Submit_Click") <----commented button

下面是VB代码：

 Dim button As New Button
 Dim xpanel As New Panel
 button.Text = "Submit"
 button.ID = "button"
 button.Height = "40"
 button.Attributes.Add("Autopostback", "true")
 button.Attributes.Add("Onclick", "Submit_Click") <----commented
 button.Attributes.Add("RunAt", "server")
 Dim trigger As New AsyncPostBackTrigger()
 trigger.ControlID = "button"
 trigger.EventName = "Submit_Click"
 AddHandler button.Click, AddressOf Submit_Click
 xpanel.Controls.Add(button)
 Dim literalx As New Literal
 submitplaceholder.Controls.Add(literalx)
 submitplaceholder.Controls.Add(xpanel)

Dim按钮作为新按钮
将xpanel变暗为新面板
button.Text=“提交”
button.ID=“button”
按钮高度=“40”
添加（“自动回发”、“true”）

button.Attributes.Add（“Onclick”、“Submit\u Click”）button.Attributes是HTML属性的集合，因此它不会按您想要的方式工作

试试这个：


button.UseSubmitBehavior = True
AddHandler button.Click, AddressOf  Submit_Click


而不是


button.Attributes.Add("Autopostback", "true")
button.Attributes.Add("Onclick", "Submit_Click") <----commented
button.Attributes.Add("RunAt", "server")



button.Attributes.Add（“Autopostback”、“true”）

添加（“Onclick”、“Submit\u Click”）在哪里执行代码？我是说，在哪个页面事件中？负载Init？使用SubmitBehavior完成了它。我很感激！
