从另一个调用一个表单

Question

I'm trying to use ShowDialog to display a pop up box from my aspx page then grab the return value from it. I created my form to be called but can't get it to register with my initial page. Here is all the code in my new form;

Partial Class MyForm
    Inherits System.Web.UI.Page

End Class

And the relevant code from my initial page;

Partial Class List
    Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
Dim request As New MyForm
End Sub

End Class

But Visual Studio doesn't recognise MyForm . What am I doing wrong?

---

Not sure if they're relevant but here's the page declaration for my new page;

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="MyForm.aspx.vb" 
Inherits="MyForm" %>

and for my original form;

<%@ Page Language="VB" MasterPageFile="../../../Site.master" 
CodeFile="List.aspx.vb" Inherits="List" %>

You can not display a pop up box in ASP.NET using ShowDialog the way you do in Windows Forms. If you need to display a pop up in ASP.NET use ASP.NET ModalPopup or JQuery dialog

Also, in ASP.NET you don't call a form as you are doing. You simply redirect to it. Check HttpResponse.Redirect Method
