Question

I have this macro running happily on a live server. It was ok in WebMatrix. Now WebMatrix has updated itself to 2 (refresh), it won’t run some macros, this being one of them:-

    @{
  //Check there are slider image page loaded
  var theCount = @Model.Descendants("SliderImagePage").Count();

  if (theCount > 0)
    {
        foreach (var theImagePage in Model.Descendants("SliderImagePage"))
          {
           var theImage = theImagePage.Media("sliderImage","umbracoFile");
           if (theImagePage.IsFirst()) 
           {
            @:<div class="slide" style="background-image:url('@Html.Raw(theImage)');display:block;"></div>
            } else {
            @:<div class="slide" style="background-image:url('@Html.Raw(theImage)');display:none;"></div>
            }
          }    
     }
  else
  {
   @: No Picture Image pages set up
  }

}

It complains that “:” is not valid at the start of a code block.

I have MVC4 and the Razor Extensions in VS2010. As far as I understand, it’s all valid. Can anyone shed any light on why it won’t pass validation?

Thanks.

The statements in the foreach loop should run fine without using @: for output:

@{
    //Check there are slider image page loaded
    var theCount = @Model.Descendants("SliderImagePage").Count();

    if (theCount > 0)
    {
        foreach (var theImagePage in Model.Descendants("SliderImagePage"))
        {
            var theImage = theImagePage.Media("sliderImage","umbracoFile");
            if (theImagePage.IsFirst()) 
            {
                <div class="slide" style="background-image:url('@Html.Raw(theImage)');display:block;"></div>
            }
            else 
            {
                <div class="slide" style="background-image:url('@Html.Raw(theImage)');display:none;"></div>
            }
        }    
     }
    else
    {
        @: No Picture Image pages set up
    }
}
