Hi Ptass,
Does the suggestion that use a common base page class in my last reply
helps? If there're still anything else we can help, please feel free to
post here.
Thanks,

| Hi Ptass,
|
| Thanks for your response. I'm afraid using Multiple partial class files
for
| aspx page is not allowed due to the fixed page compilation model.
However,
| we can alternatively provide a common base page class for our pages'
| codebehind class. For example, all the pages which will share some common
| functionalities can use one central base page class. Let's call it
| "CommonBasePage", then, let all those pages' code behind class inherit
from
| this common class so that this class's non-private functions can be
shared
| by those concrete classes. Also, in asp.net 2.0, there is one new
| attribute named "CodeFileBaseClass", we can define our common base page
's
| class through this attribute, so that the runtime will be able to
| dynamically compiled the page's structure and make the Controls
references
| in concrete pages also available in common base class. For example, here
is
| an example which use this attribute:
|
|
| =====common base page class(in App_Code)=========
|
| public partial class CommonBasePage : System.Web.UI.Page
| {
| protected Label Label1;
|
| public CommonBasePage()
| {}
|
| protected virtual void Page_Load(object sender, EventArgs e)
| {
|
| Label1.Text = SayHello();
| }
|
| public string SayHello()
| {
| return "Hello CommonBasePage.";
| }
|
| }
| ===========================================
|
| ======concrete page aspx==========
| <%@ Page Language="C#" AutoEventWireup="true" CodeFile="PageOne.aspx.cs"
| Inherits="CommonPage_PageOne"
| CodeFileBaseClass="CommonBasePage" %>
| <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
| "
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
| <html xmlns="
http://www.w3.org/1999/xhtml" >
| <head runat="server">
| <title>Untitled Page</title>
| </head>
| <body>
| <form id="form1" runat="server">
| <div>
| <asp:Label ID="Label1" runat="server"
| Text="Label"></asp:Label></div>
| </form>
| </body>
| </html>
| ===============================
|
| =====concrete page code behind==========
| public partial class CommonPage_PageOne : CommonBasePage
| {
|
| }
|
| =====================
|
| We can see that the Label1 control in concrete page can also be
accessible
| in base page as long as we define the control reference......

| |
| | re:
| | >ie., Is there a workaround ?
| |
| | No, there isn't.
| | You can't have two code-behind files for one aspx page.
| |
| | What you *can* do is :
| |
| | 1. Write utility classes and compile *them* into
| | assemblies which you can reference in your aspx pages.
| |
| | This is the way I prefer to handle this need.
| |
| | 2. Use the App_Code folder as a repository for partial classes.
| | You can place many partial class definitions in separate files in
| App_Code.
| | They will all be compiled into a single class.
