The problem is that your anonymous object property `data-icon` has an invalid name. C# properties cannot have dashes in their names. There are two ways you can get around that:

Use an underscore instead of dash (MVC will automatically replace the underscore with a dash in the emitted HTML):

    @Html.ActionLink(&quot;Edit&quot;, &quot;edit&quot;, &quot;markets&quot;,
          new { id = 1 },
          new {@class=&quot;ui-btn-right&quot;, data_icon=&quot;gear&quot;})

Use the overload that takes in a dictionary:

    @Html.ActionLink(&quot;Edit&quot;, &quot;edit&quot;, &quot;markets&quot;,
          new { id = 1 },
          new Dictionary&lt;string, object&gt; { { &quot;class&quot;, &quot;ui-btn-right&quot; }, { &quot;data-icon&quot;, &quot;gear&quot; } });

Replace the desired hyphen with an underscore; it will automatically be rendered as a hyphen:

    @Html.ActionLink(&quot;Edit&quot;, &quot;edit&quot;, &quot;markets&quot;,
        new { id = 1 },
        new {@class=&quot;ui-btn-right&quot;, data_icon=&quot;gear&quot;})

becomes:

    &lt;form action=&quot;markets/Edit/1&quot; class=&quot;ui-btn-right&quot; data-icon=&quot;gear&quot; .../&gt;

@Html.ActionLink(&quot;Login&quot;, &quot;Index&quot;, &quot;hahgshg62jjshags&quot;,new {  },new { rel = &quot;nofollow&quot;, style = &quot;color:white&quot; })

    @Html.ActionLink(&quot;display name&quot;, &quot;action&quot;, &quot;Contorller&quot;
        new { id = 1 },Html Attribute=new {Attribute1=&quot;value&quot;})
    

As my question says, after changing files and adding new files in my repository, I normally commit files with **git**, but sometimes I need all the modified / changed files copied to a folder for organizing-myself reasons.

Any option?

I am making an application in which I want to implement apple push notification  service.  I am following the step-by-step instructions given in [this tutorial](http://mobiforge.com/developing/story/programming-apple-push-notification-services?dm_switcher=true).

But still, the methods are not called. I don&#39;t know what is causing the problem. Can anyone help me?

        - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { 
            //NSString * token = [[NSString alloc] initWithData:deviceTokenencoding:NSUTF8StringEncoding];
            NSString *str = [NSString stringWithFormat:@&quot;Device Token=%@&quot;,deviceToken];
            NSLog(@&quot;Device Token:%@&quot;,str);

            //NSLog(@&quot;Device token is called&quot;);
            //const void *devTokenBytes = [deviceToken bytes];
            //NSLog(@&quot;Device Token&quot;);
        }

        - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { 
            NSString *str = [NSString stringWithFormat: @&quot;Error: %@&quot;, err];
            NSLog(@&quot;Error:%@&quot;,str);

Is there a way to put a SQL Server Reporting Services report viewer control on an ASP.net MVC view? If not...what is the best way to accomplish this? 

Viewing SSRS Reports in an ASP.net MVC Site

we have a asp.net MVC application deployed to a server, and but when there is too many request to the server, the client will just get a &quot;503 service unavailable&quot; error.   
But if I deployed the application to another server ( lower hardware configuration ), everything worked fine, even more requests it can handle well.  
My question is what possible configuration can cause the previous server to just throw out a 503 error ? (which means the requests didn&#39;t reach our application).

What possibilities can cause &quot;Service Unavailable 503&quot; error?

What I see is a string Layout property. But how can I pass a model to layout explicitly?

ASP.NET MVC Razor pass model to layout

I have a model similar to this:

    public class SampleModel
    {
         public Product Product { get; set; } 
    }

And in my controller I get an exception trying to print out

    @Html.TextBoxFor(p =&gt; p.Product.Name)

This is the error:

&lt;!-- language: lang-none --&gt;

    Exception: An expression tree may not contain a dynamic operation


If anyone can give me some clues on how to fix this I would really appreciate it!

Razor View Engine : An expression tree may not contain a dynamic operation

***Update (21st Sept 2016)*** *- Thanks to Digbyswift for commenting that this solution still works in MVC5 also.*

***Update (30th April 2012)*** *- Note to people stumbling across this question from searches etc - the accepted answer is not how I ended up doing this - but I left it accepted because it might have worked in some cases.  [My own answer contains the final solution I used][1], which is reusable and will apply to any project.*

*It&#39;s also confirmed to work in v3 and v4 of the MVC framework.*

I have the following model type (the names of the class and its properties have been changed to protect their identities):

    public class MyExampleModel
    {
      public string[] LongPropertyName { get; set; }
    }

This property is then bound to a bunch (&gt;150) of check boxes, where each one&#39;s input name is of course `LongPropertyName`.

The form submits to url with an HTTP GET, and say the user selects three of those checkboxes - the url will have the query string `?LongPropertyName=a&amp;LongPropertyName=b&amp;LongPropertyName=c`

Big problem then is that if I select all (or even just over half!) the checkboxes, I exceed the maximum query string length enforced by the request filter on IIS!

I do not want to extend that - so I want a way to trim down this query string (I know I can just switch to a POST - but even so I still want to minimize the amount of fluff in the data sent by the client).

What I want to do is have the `LongPropertyName` bound to simply &#39;L&#39; so the query string would become `?L=a&amp;L=b&amp;L=c` but ***without changing the property name in code***.

The type in question already has a custom model binder (deriving from DefaultModelBinder), but it&#39;s attached to its base class - so I don&#39;t want to put code in there for a derived class.  All the property binding is currently performed by the standard DefaultModelBinder logic, which I know uses TypeDescriptors and Property Descriptors etc from System.ComponentModel.

I was kinda hoping that there might be an attribute I could apply to the property to make this work - is there?  Or should I be looking at implementing `ICustomTypeDescriptor`?

Asp.Net MVC 2 - Bind a model&#39;s property to a different named value

A few days back I asked this question:

&gt;[Why does $.getJSON() block the browser?][1]

I fire six jQuery async ajax requests at the same controller action pretty much all at once. Each request takes 10 seconds to return.

Through debugging and logging requests to the action method I notice that the requests are serialised and never run in parallel. i.e. I see a timeline in my log4net logs like this:

&lt;pre&gt;
2010-12-13 13:25:06,633 [11164] INFO   - Got:1156
2010-12-13 13:25:16,634 [11164] INFO   - Returning:1156

2010-12-13 13:26:07,425 [11164] INFO   - Returning:1308
&lt;/pre&gt;

Looking at the network timeline in FireFox I see this:

![alt text][2]

Both the log sample above and the Firefox network timeline are for the same set of requests.

*Are requests to the same action from the same page serialised?* I&#39;m aware of serialised access to the `Session` object in the same session, but no session data is being touched.

I stripped the client side code down to a single request (the longest running one) but this still blocks the browser, i.e. only when the ajax request completes does the browser respond to any link clicking.

What I also observe here (in Chrome&#39;s developer tools) is that upon clicking on a link when a long running ajax request is executing it reports a `Failed to load resource` error  immediately which suggests that the browser has killed (or is attempting to kill and waiting?) the ajax request:

![alt text][3]

However the browser still takes an age to redirect to the new page.

Are ajax requests really asynchronous or is this sleight of hand because javascript is actually single threaded?

Are my requests just taking too long for this to work?

The problem occurs in Firefox and IE as well.

I also changed the script to use `$.ajax` directly and explicitly set `async: true`.

I&#39;m running this on IIS7.5, both the Windows 2008R2 and Windows 7 flavours do the same thing.

Debug and release builds also behave the same.

I have a `JsonResult` that is working fine, and returning JSON from some POCO&#39;s. I want to save the JSON as a string in a DB.

How do I implement reCaptcha in ASP.NET MVC and C#?

How to implement reCaptcha for ASP.NET MVC?

I&#39;m trying to implement a simple `ActionLink` that will delete records using ASP.NET MVC. This is what I have so far: 

    &lt;%= Html.ActionLink(&quot;Delete&quot;, 
                        &quot;Delete&quot;, 
                        new { id = item.storyId, 
                              onclick = &quot;return confirm(&#39;Are you sure?&#39;);&quot; 
                            })%&gt; 

However, it doesn&#39;t show the confirm box. Clearly I&#39;m missing something or I have incorrectly built the link. Can anyone help?

Delete ActionLink with confirm dialog

The problem in Html.ActionLink() is that you can&#39;t add additional html content inside the &lt;a&gt; tag that it generates.
For example, if you want to add an icon besides the text like:

    &lt;a href=&quot;/Admin/Users&quot;&gt;&lt;i class=&quot;fa fa-users&quot;&gt;&lt;/i&gt; Go to Users&lt;/a&gt;

Using Html.ActionLink(), you can only generate:

    &lt;a href=&quot;/Admin/Users&quot;&gt;Go to Users&lt;/a&gt;

So, to resolve this, you can use Url.Action() to generate only the URL inside the tag like:

    // Here, Url.Action could not generate the URL &quot;/admin/users&quot;. So this doesn&#39;t work.
    &lt;a href=&quot;@Url.Action(&quot;&quot;, &quot;Users&quot;, &quot;Admin&quot;)&quot;&gt;&lt;i class=&quot;fa fa-usesr&quot;&gt;&lt;/i&gt; Go to Users&lt;/a&gt;

    // This works, as we know it but won&#39;t pass the Area needed.
    &lt;a href=&quot;@Url.Action(&quot;&quot;, &quot;Users&quot;)&quot;&gt;&lt;i class=&quot;fa fa-users&quot;&gt;&lt;/i&gt; Go to Users&lt;/a&gt;

So, how do you pass the Area using Url.Action()?
