MVC :: Selectively Displaying Content In The Master View?
Jun 29, 2010
In any strongly-typed View, I can test for a value within the Model and display content within the View, or not, as I choose. I'm having fits trying to get this same thing to work within the Master View. Since the Master View doesn't have its own Controller, but rather uses the Controller of whatever View is being rendered at the time, it's not like I can assign an object for the Master View to inherit from as I can with a normal View. Or at least I don't know how. I've also tried setting ViewData within a base Controller class, but that hasn't worked out, and is the subject of another thread.
When any View loads, I want to be able to run a check for the current user's security group (not ASP.NET roles, but a special object for the current project). Based on their security group I'll either show certain menu items or not, and direct them to a default View for their group. I suppose that in the default Controller that rolls when the project starts, I can do a check and redirect to an action based on the security group, but that still doesn't tell me how to render out menu items based on

I have developed an ASP.NET MVC 2 application on Framework 4. I have an 'Administration' link on the home page. My query is, what is the best approach of displaying the 'Administration' link only to the users in the role administrator and hiding it from others keeping in mind the Seperation of Concern bit.

I am new to ASP.NET development and I am running into an issue using master/content pages. I have a master file that basically defines all of the layout for my site. The only thing that the content pages are supposed to display is some very basic text/images/html, made available by one ContentPlaceHolder control in the master file.
My problem is in the display. When I view the content page, none of the layout that should be inherited from the master page is displayed -- I end up with just a 'blank' page. What seems odd, is that if I look at the Design View in VS 2005, the content page appears to show the layout that is defined in the master. Here is a sample of the source for the master and one of the content pages...
Master Page: content_pages.master
<%@ Master Language="VB" CodeFile="content_pages.master.vb" Inherits="content_pages" %>

I want to include view content page in my master page: My MVC application Left Menu MainPage. The Left Menu and Main page are two contentHolders in the master page. How can I add the Left Menu (View content page) to my Master page?. The Left Menu page is going to be a permanent page. The Content in the main Page is going to change. Left Menu content needs to be the permanent content for all other pages.
I searched in the internet, but I didn't find any solution that solves my problem. Basically I need some permanent menu items in the left page. But, I should not write the code in my master page. I need to add that Menucontent as my contentPage to the master. I have tried that by adding a New content page called "LeftPage.aspx" in View/Home folder.I have referred this page to the master "Left content holder". As the ASP.Net MVC talk to the controller, the left menu is not getting displayed while page loading.If i specify the ControlAction for this left page and specify the URL as //Home/Left ;then the page is getting displayed with only the left page content.

The WorldPay payment gateway suggests using this HTML to take the customer to the payment page:
<form action="https://select-test.wp3.rbsworldpay.com/wcc/purchase" name="BuyForm" method="POST">
<input type="hidden" name="instId" value="211616">
<input type="hidden" name="cartId" value="abc123">
<input type="hidden" name="currency" value="GBP">
<input type="hidden" name="amount" value="0">
<input type="hidden" name="desc" value="">
<input type="hidden" name="testMode" value="100">
<input type="submit" value="To Payment!">
</form>
How to I put this form on my page? The problem is I have a master page which wraps the content pages content in the ASP.net form, I can't nest the forms.

I am developing a site which includes several different javascript files and libraries. For optimization purposes I have implemented YUI Compressor for .Net
This will minimize and combine my javascript files into one single file.
Now I have put this up in a MSBuild script that automatically does the compression and minimization and outputs it to a file of my choosing. However, I still wish to keep the original javascript files in my development environment. My question is simply:
Is there a good way to depending on the Debug setting for example choose which javascript to use? This to not have to change the MasterPage by hand each time I release the build.
Allow me to illustrate.
If I am running in Debug="true" I wish my MasterPage to include the following javascripts:
<script type="text/javascript" src="first.js"></script>
<script type="text/javascript" src="second.js"></script>
<script type="text/javascript" src="third.js"></script>
<script type="text/javascript" src="fourth.js"></script>
If I am running in Debug="false" I wish this to be outputted in the MasterPage:
<script type="text/javascript" src="compressedAndMinimized.js"></script>

I have over 300 content pages to create. Each has some standard styling. I would like to generate these pages, and was just wondering if there is a utility in web developer 2008 express to do so (otherwise I will just build one - but it would be great not having to do so!)

Can I ask what this error refers to, (I have had it twice now over the last couple of days and then it goes away):

I have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?

I have 3 columns in a GridView. The first is a templatefield with a button in it and then other 2 are just plain data from the database. Currently when I try to render the HTML from the GridView I see all 3 columns, but I only want to see the plain data fields. I have seen the answer as:gvQuotes.Columns[0].Visible = alse;But that doesn't work for me, because I still want to keep the first templatefield column on my page.

The trouble I have is that the 'attachment.jpg' icon shows for every lineitem (even one that does not contain an attachment). I would like to be able to selectively display this icon or show a different icon if there is NO attachment.

I am using SyndicationFeed to pull the data down and parse it. I am able to accomplish this but not without quite a bit of code.
I feel like there should be a while of doing this in a few lines of code and bind that to the ListView.
Can anyone point me at a 'really simple' way to pull rss or atom feed off of another site and bind its contents into a ListView control on my page, including the content of each item?

I have a main master page, say MasterPageMain, and a couple of folders with couple of pages in each folder which act as a child page to that master page - MasterPageMain.
Now, I have about 10 pages in one of the folder which follows a certain pattern and they could really use a nested pages since any change on some parts needs me to change all the pages which is a pain really.
I already added a Nested master page, say NestedMasterPage - which is a child of MasterPageMain
I tried to change one of the page's <%@ Page directive to NestedMasterPage, immediately, there were a lot of errors. plus I dint know where the NestedMasterPage's children content would go.
What do I need to know in order to do this succesfully?
ps: I dint do this initially because I only had 2 pages, and I dint need this at that time, as the project grew, now i see that I should have changed it much earlier..

I am rewriting a website for a company who want to keep the existing stock listing format of asp pages pulling info from an uploaded access database. I have left all the asp code alone, just changed the html around it to accommodate a better (albeit not perfect) design than previously used. I have also been adding items to the database exactly the same way the staff do it now.
However, when I view the pages, there is no content, only the html "wrapper". I get the error message displayed where the content should be: "An error occurred on the server when processing the URL. Please contact the system administrator.
If you are the system administrator please click here to find out more about this error."
I am running IIS on my local machine and as far as I am aware, it is configured correctly. I can view asp pages that do not request content from the database fine.
Pages are served on my local machine under
c:inetpubwwwroot
Database is served under
c:inetpubdb

I have a 3 level nested master pages and a content page. parent1 is the top parent, parent2 is parent of parent3 and parent3 is the parent of the content page.
I get an error 'Cannot find ContentPlaceHolder xxx...' where xxx is a ContentPlaceholder. It resides in parent2 and content page is trying to fill it.
Can content pages only use their direct parent ContentPlaceHolders or can they also use any of the higher master pages?

I'm working on an asp.net c# application that sends an email with one attachment.The attachment is a vCalendar file.
Here's the code:
StringBuilder sbCalendar = new StringBuilder();
DateTime dtStart = eventDate;
DateTime dtEnd = eventDate;[code].....
I want to get rid of that text, and display only the contents of my messageBody parameter and have the vCalendar file just attached to the mail message.How can i do this? Is this an outlook issue or a coding issue?
Edit: I'm only interested in displaying the message in Microsoft Outlook. I've looked into the source of the message (in Outlook right click > View Source) and the text i want to get rid of is within the <body></body> html tags of the message)
