I have a default.aspx page, another asp page needs to be a copy of it. lets call that Revised.aspx
I've copied over all the front end Default.aspx code, building all the way. It was fine. When I copied the methods from the codebehind to the Revised.aspx.cs page, it gives errors saying the var names etc do not exist in the current context - even though they do?
I'm missing a the code browser when I create pages that have the code not placed in a seperate file. For pages with .asp.vb files I get the browser correctly.
I think it's called a code browser but just in case it's not I mean the dropdown that shows Page Events, Buttons and other controls that can be selected along with their events.
How do I turn on those dropdowns for pages with code behind that uses <script> tags in the actual .aspx page?

View 4 RepliesNow, I'm working on a project where I don't really understand how can I do things without multiple inheritance, without duplicating code.
Here's the situation. There is a website with a home page and other pages inheriting from a masterpage (the home page does not inherit from). Both the page and the masterpage are performing some stuff: custom login, statistics, loading of users settings for customization, etc. For the moment, the solution is crappy, since the source code for those tasks is just copied twice.
The home page class inherits from Page. The masterpage, on the other hand, inherits from Masterpage. Logically, it would be great to inherit from a common class too, but it's multiple inheritance, so it's impossible.
So what to do instead?
I thought about several ways, but dislike them:
Create a standalone class which will be called from the page/masterpage class. So for example instead of writing bool isDisplayingTips = this.CurrentUser.IsDisplayingTips, I would write bool isDisplayingTips = this.SharedObjects.CurrentUser.IsDisplayingTips. I don't like it, since it's longer to write. Create a "real", empty, common masterpage, and inherit both the home page and the masterpage from it. Not only it will require to write more code to access masterpage parameters, but it will also slow the things down, requiring an additional masterpage on each request.
I need to create a code that reads the QueryString and set a value on the Session and on the end of the page I need to clear the Session.
How can I make a code like this to run on all .aspx pages?
i have to insert a "Google Analytics Tracking Code" java script to all pages in my website, before </body> tag.There is no master pages so i could not use them. Is there any way to insert a code from global.asax into all pages? If i use application_endrequest then it goes to the very last line which is after </html> tag.
View 3 RepliesI have some menu html code that I want to share among several pages, so that if I change a menu item it gets updated across all pages.
Is this possible in VWB? I'm using the 2010 Express version.
I'm just starting out learning ASP.NET. From what I understand, ASP.NET differs from old school ASP in that the logic code for a page exists in as separate file rather then being embedded in the ASP page. So when a user requests a page like ShoppingCart.aspx the server reads the directive at the top ...
<%@ Page Title="" Language="C#" MasterPageFile="~/Styles/Site.Master" AutoEventWireup="true"
CodeBehind="MyShoppingCart.aspx.cs" Inherits="TailspinSpyWorks.MyShoppingCart" %>
This tells the server what file and what class in the file is associated with the page. The code behind class also has member variables that correspond to each control on the page, and provide a way for code in the code behind file to manipulate the controls.
First, do I understand this correctly?
Second, could a site be setup with two separate ASPX pages with identically named controls, which both had a directive pointing to the same file and class? Would you even want to do this? Both pages could have the same functionality but a different layout. I was thinking this could be a way to create separate "desktop" and "mobile" versions of a page with out duplicating content in the code behind files.
I guess ultimately what I'm wondering, is if there a way to define an abstract page? Say create an abstract page definition that says a page must have controls "cart_list", "total_lbl", but then be able to have multiple pages that inherit from this abstract page?
Is it possible to do something like this in regular ASP.NET (or something similar):
<ul>
<% foreach (var item in Model) { %>
<li id="<%: item.Id %>">
blah blah
</li>
<% } %>
</ul>
I need to do a gird, but I want to control how the html table is output.
Is there a way to check for errors in unopened *.ASPX pages. For example, if you change the name of a function Visual Studio will catch the error on the page and list it in the "Error List" only if the page is opened and being validated?
How do i find out about the following without running the page through the webserver or opening the page to be validated in VS?
<script runat="server">
Public Sub MyFunciton()
Undefined_FUNCTION()
End Sub
</script>
I'm working on a master page, I right click and add a content page, However now I am missing the code behind. So if I make a default2.aspx there is no default2.cs. I can't figure out what I did, It was functioning perfectly before.
View 3 RepliesI am taking over for a website in ASP.Net (VB.Net) where the live site is compiled code. So there's no code behind pages. So other than the ASP.Net pages, it's just DLL files in the bin folder.It's also at an ISP where I have no control over the server to remote in.
I have gotten from the client, what I believe to be the latest and greatest code. So there's code behind pages and also a vbproj file. It seems to be have done in an early version of Visual Studio.Thinking maybe 2003.I only have Microsoft Visual Web Developer 2010 (I've been using) and VS2005.So I made a very basic change just to test the waters and built the website, which made a brand new DLL for the site in bin. Also new pdb and xml document. It works fine on dev.I uploaded just this DLL to live. However on live, when I get to the part where I'm submitting a form.I get a very non descript error.

I need to display c#, vb.net or any source code on a web page. The source code that will be displayed should indented, colored as we see in any IDE. I am not sure how would i achieve this. Is there any in-built control available in asp.net that i can use to display the code or can someone tell me how can i achieve this.

View 2 RepliesI need my child pages to be able to set the values of certain properties of the Master page before loading. In other words, how my application builds the Master page for the client depends upon what properties are set by the child pages on the back-end. For example:
public partial class mstrPage : System.Web.UI.MasterPage
{
public int Rows { get; set; }
public int Cols { get; set; }
protected void Page_Load(object sender, EventArgs e)
{
/* Build a .NET two-dimensional-array of divs
that is <Rows> tall and <Cols> wide. */
}
}
In this example, the child page needs to set the values of <Rows> and <Cols> before Page_Load() is invoked for the Master. This is fairly simple to accomplish with inheritance in OOP, but ASP.NET web pages do not "inherit" their master pages in the code-behind. In the given example, what would the code-behind look like for the ASP.NET child page that sets these properties?

I'm trying to add Google Adword conversion code script to certain aspx pages in our website but I'm running into an issue with the site using master pages. The Google instruction said to place the code before the body tag but with master pages being used the code will be on all the pages using the master page. I would like setup it up where certain pages use individual conversion codes with others not using anything. Any suggestions or examples would be appreciated. Also, I'm using C#.
