You need to put the entire ternary expression in parenthesis.  Unfortunately that means you can&#39;t use &quot;@:&quot;, but you could do something like this:

    @(deletedView ? &quot;Deleted&quot; : &quot;Created by&quot;)

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

I would like to append a new line to an existing file without erasing the current information of that file. In short, here is the methodology that I am using the current time: 

    import java.io.BufferedWriter;
    import java.io.FileWriter;
    import java.io.Writer;

    Writer output;
    output = new BufferedWriter(new FileWriter(my_file_name));  //clears file every time
    output.append(&quot;New Line!&quot;);
    output.close();

The problem with the above lines is simply they are erasing all the contents of my existing file then adding the new line text. 

I want to append some text at the end of the contents of a file without erasing or replacing anything.

what is the best way to check if a Data Table has a null value in it ?

Most of the time in our scenario, one column will have all null values.

(This datatable is returned by a 3rd party application - we are trying to put a valiadation before our application processes the data-table)

Not having much luck, I have the following if/else statement in Razor which works perfectly

 

    &lt;small&gt;
      @if(deletedView){
         @:Deleted
      } 
      else {
         @:Created
      } by
    &lt;/small&gt; 

I am trying to do something like this:

    &lt;small&gt;
      @(deletedView) ? @:Deleted : @:Created by
    &lt;/small&gt;

But that fails miserably. What is the proper syntax?

I&#39;m trying to get an ASP.NET MVC 3 site running on IIS 6.0. 

Currently when I request a page from the server it gives the following error:

&gt; Parser Error Message: This method cannot be called during the application&#39;s pre-start initialization stage.

on this line:

    &lt;add name=&quot;MyMembershipProvider&quot; type=&quot;NS.MyMembershipProvider&quot; connectionStringName=&quot;MyDatabase&quot; applicationName=&quot;/MySite&quot;/&gt;

I&#39;m completely stumped and don&#39;t have much of a clue about the ASP.NET application lifecycle, let alone the differences between 6.0 and 7.0. Reading through the MSDN pages on it hasn&#39;t seemed to help much. 

Does anyone have any insight or any good links for investigation? :)

Trying to get my project updated to MVC3, something I just can&#39;t find:

I have a simple datatype of ENUMS:

    public enum States()
    {
      AL,AK,AZ,...WY
    }

Which I want to use as a DropDown/SelectList in my view of a model that contains this datatype:

    public class FormModel()
    {
        public States State {get; set;}
    }

Pretty straight forward: when I go to use the auto-generate view for this partial class, it ignores this type.

I need a simple select list that sets the value of the enum as the selected item when I hit submit and process via my AJAX - JSON POST Method. 

And than the view (???!):

        &lt;div class=&quot;editor-field&quot;&gt;
            @Html.DropDownListFor(model =&gt; model.State, model =&gt; model.States)
        &lt;/div&gt;

thanks in advance for the advice!

MVC3 Razor DropDownListFor Enums

What is wrong with the following?

    @Convert.ToDateTime((@item.Date.ToShortDateString()),&quot; dd - M - yy&quot;)

@item.Date is showing 20/11/2005 12:00 a.m and I want to display 20 Nov 2011

Does anybody know how to get the generated html of a view inside an action?

Is it something like this:
  
    public ActionResult Do()
    {
        var html = RenderView(&quot;hello&quot;, model);
    ...
    }

In MVC3 Razor, how do I get the html of a rendered view inside an action?

I&#39;m trying the render an HTML list that looks like the following, using the Razor view engine:

    &lt;ul&gt;
      &lt;li id=&quot;item_1&quot;&gt;Item 1&lt;/li&gt;
      &lt;li id=&quot;item_2&quot;&gt;Item 2&lt;/li&gt;
    &lt;/ul&gt;

The code that I am attempting to use to render this list is:

    &lt;ul&gt;
    @foreach (var item in Model.TheItems)
    {            
      &lt;li id=&quot;item_@item.TheItemId&quot;&gt;Item @item.TheItemId&lt;/li&gt;
    }
    &lt;/ul&gt;

The parser is choking, because it thinks that that everything to the right of the underscore in the id attribute is plain text and should not be parsed.  I&#39;m uncertain of how to instruct the parser to render TheItemId.

I don&#39;t want to but a property on the model object that includes the item_ prefix.

I also have to keep this syntax as I am using the list with JQuery Sortable and with the serialize function that requires the id attribute to be formatted in this syntax.
