How do you check if a Multiline textblock (simple text editor) is empty?

Razor

How do you check if a Multiline textblock (simple text editor) is empty in Umbraco using Razor?

I have a property on an Image MediaType that I am pulling and outputting, however, when I check if the property is empty the check is not working, so it is still outputting.

Here is my check below:

<ul class="slides">
 @foreach(dynamic slideImage in mediaFolder.Children){
    var slideCaption = @slideImage.caption.ToString();
   <li>
@*@if(slideImage.caption.GetType() != typeof(umbraco.MacroEngines.DynamicXml))*@
@* @if(!String.IsNullOrWhiteSpace(@slideCaption))*@

@if(@slideCaption != String.Empty){
<img src="/imagegen.ashx?&[email protected]" title="@(slideImage.GetValue("caption"))" alt="@(slideImage.GetPropertyValue("altTag"))" data-caption="#@slideImage.Id"  />
<p class="flex-caption" id="@slideImage.Id">@slideImage.GetProperty("caption")</p> 
}
else{Empty Property...supposedly}
    </li>                                          
       }
</ul>

It is not getting past my IF statement if the property box is empty.

I have verified that the textblocks are empty but it seems like in Umbraco it property is not.

Any help is greatly appreciated.

Hi Carlos,

You have hit on a couple of annoying bugs in DynamicMedia here, below is my suggested workaround using uQuery

Try this:

<ul class="slides">
     @foreach(var slideImage in mediaFolder.Children){

         int mediaId;
         if (!int.TryParse(slideImage.Id, out mediaId))
         {
             mediaId = 0;
         }
         var mediaItem = uQuery.GetMedia(mediaId);
         var imageCaption = string.Empty;
         if (mediaItem.HasProperty("caption"))
         {
             imageCaption = mediaItem.GetProperty<string>("caption");
         }

       if(!string.IsNullOrEmpty(imageCaption)){
         <li>
           <img src="/imagegen.ashx?&[email protected]" title="@imageCaption" alt="@slideImage.altTag" data-caption="#@slideImage.Id"  />
           <p class="flex-caption" id="@slideImage.Id">@slideImage.caption</p> 
         </li>                                          
       } 
    }         
    </ul>

the messed up thing is that we have a test website. The code I have above WORKS in the test site and now our Live site. So I don't quite know if it is a bug. The Umbraco versions are the same, The code in the Macro are the same. I don't get it.

Probably the difference is content, the problem is cause by this issue http://issues.umbraco.org/issue/U4-579
