Web Forms :: How To Displaying Source Code On Aspx Pages

Jul 11, 2010

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.

Copy & Paste Controls In Source View Of ASPX Pages - Force VS Not To Touch IDs?

Feb 18, 2010

If I drag a control from the toolbox in Visual Studio (2008+SP1) into an ASPX page I get a proposal for an ID: <asp:Button ID="Button1" runat="server" Text="Button" /> That's nice and helps not to forget to assign an ID. Most of the time I rename the ID like: <asp:Button ID="MySpecialButtonForSpecialTask1" runat="server" Text="Button" />

Now I have a task 2 (3, 4, ..., n) and need a button "MySpecialButtonForSpecialTask2". So I copy and paste the first one with ID="MySpecialButtonForSpecialTask1". That's the result: <asp:Button ID="Button1" runat="server" Text="Button" /> That's not nice since I need to change now "Button1" to "MySpecialButtonForSpecialTask2" but I would prefer to change "MySpecialButtonForSpecialTask1" to "MySpecialButtonForSpecialTask2". Is there any setting or trick in VS to prevent assigning new IDs after copy and paste?

I'm not looking for the option "Tools > Options > Text Editor > HTML> Miscellaneous > Auto ID elements on paste in Source view" since it also turns off creating IDs for controls inserted from the toolbox. I only would like to switch off this when copy & paste.

Configuration :: IIS 6.0 Not Displaying Default.aspx Pages After Updating Site To .NET 4.0?

Jul 21, 2010

I just recently upgraded a site from 3.5 to 4.0. After editing the web.config, creating a new app Pool in IIS, configuring the site to use 4.0 and the new app Pool, I can no longer browse to any default.aspx page without explicitly typing 'default.aspx'. This site was originally written for .NET 2.0, upgraded to 3.5, and finally updated to 4.0 a few days ago.If I try to browse to http://[mysite]/ I see the following error:
Server Error in '/[mysite]' Application.The resource cannot be found. Description:TTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.Requested URL: /Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1However if I browse to http://mysite/default.aspx, everything works fine.

If I undo all the changes made to the web.config, and revert the site back to the app Pool used for 2.0/3.5 the site loads and runs fine. Restarting IIS will solve the problem for an hour to a day, but the issue will always come back. Other sites running on our sever which were not originally made in 2.0, but 3.5, have upgraded to 4.0 without this issue.

Aspx Fields Missing & Disappears From Source Code

Oct 27, 2010

the page form has a hidden slide-in on click of a div, section allowing the user to 'make a reservation'. The jQuery used to animate the slide works fine, and happens on click on the ticky check-box (id="rescheck"). The problem is, instead of all the fields contained within the hidden div displaying on click of the checkbox, and thus sliding into view along with their labels, only one text field input shows, and nothing else. Checking the source code shows that these missing labels & fields are not even in the source code, dispite being in the page code when viewed (and edited) within MS Visual Studio 2008. As you can see, the fields and their labels seem to just disappear in the browser! I have NO idea whats causing this, and am not sure where to go with it next.

This is my PAGE code, from Visual Studio:

<fieldset id="resreq">
<legend>Make a Reservation?</legend>
<label for="rescheck" class="rescheck">If you would like to reserve a table at Madrasi check here:</label>
<input id="rescheck" type="checkbox" class="rescheck" runat="server" />
<div id="reservationfields">
<div id="res_when">
<div>
<asp:Label ID="lblDate" runat="server" AssociatedControlID="txtDate">On which date would you like us to reserve your table?</asp:Label>
<asp:TextBox ID="txtDate" runat="server" CssClass="res_date" />
</div>
<div>
<asp:Label ID="lblTime" runat="server">and for what time?</asp:Label>
<asp:TextBox ID="txtTime" runat="server" CssClass="res_time" />
</div>
</div><!-- close res_when -->
<div>
<asp:Label ID="lblBranch" runat="server">At which restaurant would you like to make your reservation?</asp:Label>
<asp:DropDownList ID="ddlBranch" runat="server">
<asp:ListItem Text="Select a Restaurant" Value="" />
<asp:ListItem Text="Restaurant 1" Value="Restaurant 1" />
<asp:ListItem Text="Restaurant 2" Value="Restaurant 2" />
</asp:DropDownList>
</div>
<div>
<asp:Label ID="lblPeople" runat="server" AssociatedControlID="txtPeople" Text="Number of Guests:" />
<asp:TextBox ID="txtPeople" runat="server" />
</div>
<div>
<asp:Label ID="lblDOB" runat="server" AssociatedControlID="txtDOB">Date of Birth:</asp:Label>
<asp:TextBox ID="txtDOB" runat="server" />
</div>
</div><!-- close reservation fields -->
</fieldset>
...and this is the Source Code when you 'view source' in the browser:
<fieldset id="resreq">
<legend>Make a Reservation?</legend>
<label for="rescheck" class="rescheck">If you would like to reserve a table at Madrasi check here:</label>
<input name="ctl00$cpcMain$rescheck" type="checkbox" id="ctl00_cpcMain_rescheck" class="rescheck" />
<div id="reservationfields">
<div id="res_when">
<div>
<input name="ctl00$cpcMain$txtDate" type="text" id="ctl00_cpcMain_txtDate" class="res_date" />
</div>
<div>
</div>
</div>
<div>
</div>
<div>
</div>
<div>
<span id="ctl00_cpcMain_rvDOB" style="color:Red;visibility:hidden;">You have entered your Date of Birth incorrectly (dd/mm/yyyy).</span>
</div>
</div><!-- close reservation fields -->
</fieldset>

C# - Accessing Source Code Generated From ASPX/ASCX Files?

Mar 3, 2010

You've probably noticed that when you debug an error which comes from an ASPX or ASCX file (literally, not from a corresponding code-behind file), ASP.NET displays an error page showing you the source file and the line on which the error occurs. The source file being displayed is automatically generated from parsing the page/control. The question is: how can I see this source file without purposely causing an exception?

I'd love to hear that there is some programmatic way (the complexity doesn't matter) to generate source files (preferrably, .cs) from a series of ASPX/ASCX files.

Example. Consider the following ASPX page (the code-behind file may even be absent):

<%@ Page Language="C#"%>
<%@ Register Assembly="AspxGen" Namespace="AspxGen" TagPrefix="ag" %>
<html>
<head><title>Some Title</title></head>
<body>

[Code]....

d:DevAspxGenAspxGenDefault.aspx(9,80): error CS0103: The name 'ThereIsNoSuchProperty' does not exist in the current context

This means, theoretically I can open the .CS files passed to the compiler (namely, App_Web_sqj3krv3.0.cs and App_Web_sqj3krv3.1.cs) and see what ASP.NET has generated from my ASPX markup. Trying to rephrase the previous question: how can I obtain this file from an arbitrary ASPX file (assuming that the file is correct and hence no info will be given on where to search)?

C# - Can Two ASPX Pages Inherit The Same Code Behind Class

Sep 4, 2010

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?

Getting The Errors For Code In Unopened .aspx Pages?

May 12, 2010

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

C# - Add Google Adword Conversion Code Script To Certain Aspx Pages In Website?

Feb 22, 2011

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#.

IIS 6/7 Threading - Long Running Aspx Page Keeps Other Aspx Pages From Loading

Oct 11, 2010

I wrote a test page that does a bunch of busy work in a method called at page load. This process as I have it now takes around 12 seconds.

If I try to load another page while the first long running page is loading, this second page doing nothing except writing out a world, it doesn't load until the first long running page is finished.

Why is this the case? I would think IIS would be able to handle multiple concurrent connections, it seems crazy that one long running page would stop every other page in the application from loading. I must be missing something or not understand how IIS works.

I would think multiple independent requests would be spawned on different threads. Is this only the case if the requests are from different sessions entirely? Are all requests from a single session bound to a single thread?

View Page Source - Displaying Chart In Project

Mar 18, 2010

I am trying to display a couple of charts of my site. The two charts are here: [URL]. I did a right-click and "view page source", copied the pertinent information into my project and when I run it, I only see a parameter, or outline of where the chart should be. I see pretty much everything EXCEPT for the chart. I've been to other sites and was able to display the chart DJIA chart in my project, but it doesn't update throughout the day. Is there an easy way to set up these kinds of charts, or do you need some kind of direct connection to one of the exchanges or some such thing?

Web Forms :: How To Get The Pretty URL With An ASPX Pages

Mar 25, 2010

How do i get the pretty URL with an ASPX pages. I have listed a couple links below and their associated print page url. As you can see it resembles the Class instantiation method of declaring object but is used for a webpage with its extension.

I was wondering if this method can be used or if this is a URL rewrite to mask all the querystrings and sub directories being referenced. I remember doing stuff like this when i was working on a UNIX system using the .htaccess file to mask effective query
string being shown. I believe they called it a Clean URL, i maybe wrong as it has been well over 8 years since i dealt with the Unix .htaccess file and massaging urls with it.

For instance, look at the MSDN site pages:

http://msdn.microsoft.com/en-us/library/system.servicemodel.actionnotsupportedexception.aspx

Now when you want to print it:

http://msdn.microsoft.com/en-us/library/system.servicemodel.actionnotsupportedexception(printer).aspx

Now you select the same page but choose a different framework than its birth:

http://msdn.microsoft.com/en-us/library/system.servicemodel.actionnotsupportedexception(VS.100).aspx

and the print URL:http://msdn.microsoft.com/en-us/library/system.servicemodel.actionnotsupportedexception(VS.100,printer).aspx

As you can see they are not visually passing query strings but more like Class parameters. Is this just a simple URL rewrite after the page is loaded so the user doesnt see the query string information?
