I'm trying to output some Twitter handles in ASP.NET MVC3 in conjunction with the Twitter @Anywhere API, and I haven't been able to figure out how to actually escape the "@" symbol in a Razor view. Does anyone know what the syntax is for escaping the "@" character in Razor? I've tried using <text></text> and that results in a JIT error.

I have upgraded my MVC2 project to MVC3 project and now I want to change the viewengine from standard aspx to the Razor viewengine. I have tested to create a new MVC3 project with the Razor viewengine and this works just fine, but now I want to uppgrade my existing MVC3 aspx viewengine project to a project with the Razor viewengine.

The following code works for webform view engine.
<% Model.Categories.ForEach(x => { %>
<li><a href="#">@x.Name</a></li>
<% }) %>
I wrote the above code as below in razor view:
@Model.Categories.ForEach(x => {
<li><a href="#">@x.Name</a></li>
})
But this doesn't work. Is there any way to achieve this in razor view?
I am using Actionfilter to globally filter our HTML comments from all action methods and in all controllers. It simply overrides OnActionExecuting and runs the response through a regex to filter the comments. I am also using RenderAction to render some more complicated widgets in my website. There is no caching in place, I just use Renderactionto keep my code as simple possible.
When calling RenderAction from within a Razor View, I get an error message telling me that "Filtering is not allowed". The problem does not occur when calling RenderAction from within an aspx View. It only occurs when calling RenderAction from within a Razor View. In case it matters: the view being rendered is implemented with ASPX. Is this a bug or a known limitation?
I have a Page.cshtml similar to the following (that does not work):
@{
Layout = "../Shared/Layouts/_Layout.cshtml";
var mycollection = (ViewBag.TheCollection as IQueryable<MyCollectionType>);
}
<h2>@ViewBag.Title</h2>
content here
@if (mycollection != null && mycollection.Count() > 0)
{
@section ContentRight
{
<h2>
Stuff
</h2>
<ul class="stuff">
@foreach (MyCollectionType item in mycollection )
{
<li class="stuff-item">@item.Name</li>
}
</ul>
}
}
As I said, this does not work. I want to not define the section if there's nothing in the collection. Is there any way to have something like this work? If not, what are my other options? I'm very new to this Razor ViewEngine. Edit In my layout i have:
@if(IsSectionDefined("ContentRight"))
{
<div class="right">
RenderSection("ContentRight")
</div>
}
what i don't want is the div to output when the section is empty.

I am woking on a MVC project which require me to put all controllers, models and views into a folder called Mvc instead of the project root, I created a custom viewengine, here is the code:
[Code]....
My Application_Start:
[Code]....
It does not work, when I request [URL], I got: The view 'Index' or its master could not be found. The following locations were searched:
~/Mvc/Views/Index.aspx
~/Mvc/Views/Index.ascx
~/Mvc/Views/Shared/Index.aspx
~/Mvc/Views/Shared/Index.ascx
I expect the custom viewengine to find the view at: ~/Mvc/Views/Home/Index.aspx
I've read about how I can create a custom viewengine however is it possible to load an assembly which has a method decorated by my own custom attribute say..[RenderWithView], then I dynamically invoke that method and apply a view engine to it, finally returning the html?

The thing is that now when I run my site..I get the following error: CS0246: The type or namespace name 'WebMatrix' could not be found (are you missing a using directive or an assembly reference?) and I just cant find a way to solve this..I have added the references.
i'm upgrading my asp.net mvc app to the MVC 3 from mvc 2. I had everything set up so that there were no areas, but now i have to move the old application into its own area so i can start a new one. The new area is working great, but for some reason, when i try to go into the area where the old app was, it looks for the views to be in the views folder in the root of the app, instead of in the views folder in the area.
View 2 RepliesI am following Chris Pietschmann's solution for theming in ASP.NET MVC.
One thing I have noticed is that the view name is not being retrieved from the ViewLocationCache on subsequent requests. I am using ASP.NET MVC 2.0 RC
When the following code is executed:
this.ViewLocationCache.InsertViewLocation(controllerContext.HttpContext, cacheKey, virtualPath);
and I hover over this.ViewLocationCache it just returns {System.Web.Mvc.NullViewLocationCache} - suggesting nothing was added?
I have such code:
<%# (int)Eval("Favorites") > 0 ? "<a href="history.aspx?visitorid=<%# Eval("VisitorID") %">Favorites</a> / " : ""%>
where I show a link if value>0 .. However it gives me a bad url(history.aspx?visitorid=%3C%#%20Eval) when I put visitorID=<%#...%>inside another Eval<%#..%>
Are the any functions in C# that handle escape/unescape like JavaScript?
I have a JSON string like this:
{"Feeds":[{"Url":"www.test.com","FeedType":"Twitter"},{"Url":"www.test2.com","FeedType":"Youtube"}]}
Which looks like this after escape()
%7B%22Feeds%22%3A%5B%7B%22Url%22%3A%22www.test.com%22%2C%22FeedType%22%3A%22Twitter%22%7D%2C%7B%22Url%22%3A%22www.test2.com%22%2C%22FeedType%22%3A%22Youtube%22%7D%5D%7D
In my C# code I would like to unescape this string so that it looks exactly the same as it did before the escape()
I have a field with product name
abc® product1
If I get the data from the database and databind it to the dropdownlist. It becomes
<option value="2">abc ® product1</option>
I don't want ASP.net to escape the ® to %amp;reg.
buildLetter.Append("</head>").AppendLine();
buildLetter.Append("").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
Assume the above contents resides in a file. I want to write a snippet that removes any line which has empty string "" and put escape character before the middle quotations. The final output would be:
buildLetter.Append("</head>").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
The outer " .... " is not considered special chars. The special chars may be single quotation or double quotation. I could run it via find and replace feature of Visual Studio. However, in my case i want it to be written in c# or VB.NET
I need to be able to navigate through the file system from an asp.net page and gather metadata on files, directories ... The simple code I've put together makes a list of directories/files in a given location and has everything displayed as a link button. My problem is with link buttons under which I have paths that include ampersands and blanks. Here's a sample of code:
[Code]....
The Response.Redirect("aPage.aspx?d="+ e.CommandArgument.ToString()); line has the problem ... the e.CommandArgument.ToString() shows a truncated path that stops just before the first ampersand detected. I tried escaping the ampersand with a backslash but it did not work ... somehow I guess it's not exactly the character that's causing the problem ..
<asp:Button ID="myButton" runat="server"
OnClientClick='confirm("How do you escape this apos'trophe?")' />
what is an alternative for javascript escape function in c# for e.g suppose a string:"Hi Foster's i'm missing /you" will give "Hi%20Foster%27s%20i%27m%20missing%20/you" if we use javascript escape function, but what is the alternative for c#. i have searched for it but no use.

View 2 RepliesI find myself doing a ton of jquery these days so I started to abstract out some of the common things I do into snippets. I look forward to sharing these with the community, but i'm running into an issue right now. The literals in snippets are defined by adding dollar signs ($) around the name of the literal to delimite where the value you would like to provide will go. This is difficult because jQuery uses the dollar sign notation in order to use a lot of it's functionality. Does anyone know the escape sequence for snippets so I am able to use the dollar sign, and have my snippets still function?
View 7 RepliesI'm doing some databinding inside a ListView ItemTemplate, but I suspect this is a problem for any databinding/template situation. I want to write something like:

But I get a YSOD with an error message that the server tag is not well formed. How do I persist non-visible data inside my ListViewItem?
I have a web application.
I user Forms authentication and set Login.aspx as the Login url.
So when I try to enter any other page in my address bar Iam redirected to Login page as per its setting.
But now I need to give a link called Register in Login.aspx page.
Clicking on Register link should take me to Register.aspx page.
But as per authentication settings Iam redirected to Login page.
So is there a way to omit or escape the register.aspx page from this authentication setting.
