i think you can just use the is or not syntax...

if(@n.GetProperty("featureOnHomepage") {
...
} 

I'd have though that should work, but it just gives an error when rendered to the page:

Cannot implicitly convert type 'umbraco.interfaces.IProperty' to 'bool'

so maybe

if(@n.GetProperty("featureOnHomepage").AsBool) {
....
} 

Oh, dear.. that gives an error on save:

Cannot convert method group 'AsBool' to non-delegate type 'bool'. Did you intend to invoke the method?

Tried adding parentheses to AsBool(), but that slo errored on save:

'umbraco.interfaces.IProperty' does not contain a definition for 'AsBool' and the best extension method overload 'System.Web.WebPages.StringExtensions.AsBool(string)' has some invalid arguments

... and it didn't work as AsBool(@n.GetProperty("featureOnHomepage")) either...

what about this page here... does that help?

looks like maybe we have to use true and false not 1 and zero??

reference this page as well...

actually wait... i think i see what you need...

i think you can put a where on your for each...

@foreach(DynamicNode n in nodes.Where("featureOnHomepage")) {

Thanks for thinking about this. Yes, this looks like it should work... but it gives an error on save:

'System.Collections.Generic.IEnumerable' does not contain a definition for 'Where' and the best extension method overload 'System.Linq.Enumerable.Where(System.Collections.Generic.IEnumerable, System.Func)' has some invalid arguments

Argh!

Damn, it doesn't work after all: it was just that I hadn't published some nodes since adding the "featureOnHomepage" property!

Anybody have any ideas?

Okay, so how much of the above code is working? What I see you're doing atm., is to check if n has a property of alias "featureOnHomePage" that has a value, but I don't see you actually check if that value is true or false?

Edit: And in your first example, shouldn't it be true instead of 1? Or is that the custom part? :)

It's much easier to help, if you pasted your current code and the error message you are getting. 

Good luck!

I am experiencing a very similar error. I have two different Document types. Both Document Types have the property "displayInTopNavigation". I iterate through these documents in the same Razor script:

@using umbraco.MacroEngines

@{
  var languagePage = Model.AncestorOrSelf(1);
  <ul>
  @{
    foreach (var firstLevelPage in languagePage.Children)
    {
      try 
      {
        if (firstLevelPage.NodeTypeAlias == "Folder" || firstLevelPage.NodeTypeAlias == "Page")
        {
          <div> @firstLevelPage.Name : @firstLevelPage.displayInTopNavigation.GetType() <br/>  </div>
          if (firstLevelPage.displayInTopNavigation)
          {
            <div> First Level Page </div>
          }
          else
          {
            <div>@firstLevelPage.Name not in top navigation</div>
          }
        }
      }
      catch (Exception e)
      {
        @e.Message<br/>
      }
    }
  }
  </ul>
}

The curious thing is, that the Razor script seems to interpret the "displayInTopNavigation" sometime as a System.Boolean, sometimes as a System.String. The <div> @firstLevelPage.Name : @firstLevelPage.displayInTopNavigation.GetType() <br/>  </div> statement puts out that the property is one time a boolean, one time a string. I am totally puzzled since I quadruple-checked the properties of both document types, I even let someone else check, and they are in fact "True/False".

Could this be a bug or is there some subtle thing with Razor I didn't consider right?

I am using umbraco 4.7.1.1

is working on a reply...
