Im i remove the ToString() i get an error saying:

Error loading Razor Script RenderBoxJob.cshtml
The best overloaded method match for 'string.IsNullOrEmpty(string)' has some invalid arguments

Try updating the if to the following:

if(Model.HasValue("WhiteBoxText"))

Then i get this error: 

Error loading Razor Script RenderBoxJob.cshtml

Cannot invoke a non-delegate type

By the way, it is a Rich Text Editor field i want to make the check on, if that makes any difference? 

Isolate a test and rip everything else out except @Model.WhiteBoxText

If i remove everything, the field is being outputted... 

Doh, just realised it might be this:

<div style="position:absolute; bottom:0; right:0;"><img src="@Model.Media("whiteBoxImage", "umbracoFile")" /></div>

I think you have to change the quotes to:

<div style="position:absolute; bottom:0; right:0;"><img src='@Model.Media("whiteBoxImage", "umbracoFile")' /></div>

Then it works :) :) :) 

But any idea why it fails with HasValue() ?  

It works with the solution: 

@inherits umbraco.MacroEngines.DynamicNodeContext
@{
 
if(@Model.whiteBoxText != null && @Model.whiteBoxText.ToString() != ""){
<article class="other-jobs grey-gradient" >
    <div class="text">
      @Model.whiteBoxText
    </div>
    <div style="position:absolute; bottom:0; right:0;"><img src="@Model.Media("whiteBoxImage", "umbracoFile")" /></div>
</article> 
}
  }

Yea it's probably because it's case sensitive. You should be checking for "whiteBoxImage" instead of "WhiteBoxImage" I think?

EDIT: oh my first solution worked? lol I deleted it thinking it was wrong, ha.

Hi Nicky,

I think your test should be:

if(!string.IsNullOrEmpty(@Model.whiteBoxText.ToString())){

instead of

if(string.IsNullOrEmpty(@Model.whiteBoxText.ToString())){

If you want to write ou the HTMl on not empty nodes.

^ Ahhh, that's exactly it.. my silly eyes are failing me today!

Hi, actually when you write "ToString()" everything is casted to string. Otherwise despite the compiletime-type of the parameter you pass to the isNullOrEmpty() is dynamic the method "IsNullOrEmty" expects that the runtime-type of the parameter would be exactly the "string" type. So that if it's not a case then a runtime error is thrown.

Just for info: in .Net 4 you could replace the call to IsNullOrEmpty by a call to IsNullOrWhiteSpace. This does the same checks but also returns true if the string parameter consists of white spaces.

Cheers,

Michael.
