.OrderByDescending("Id")

Razor

I am having trouble using .OrderByDescending("Id") in sorting items before running throug items to render html. My code works without .OrderByDescending("Id") but adding does not throw error but only shows blank rendering in browser:

@inherits umbraco.MacroEngines.DynamicNodeContext
@{ 
var  folderId = Model.GetPropertyValue("mediaFolder");

    var  chosenMedia  =  Model.MediaById(@folderId).OrderByDescending("Id");

    if  (chosenMedia.NodeTypeAlias  ==  "Folder")
 {
     foreach  (var  img  in  chosenMedia.Children)
     {
         if  (img.NodeTypeAlias  ==  "Image")
         {                   
             <div>
                 Navn: @img.name
             <img  src="@img.umbracoFile" width="700px" />
                     </div>
         }
     }
 }

}

.Children.OrderBy("Name") works fine. .Children.OrderByDescending("Name") does not.

Hi Guy

I think you should put the OrderByDescending on your look rather than in your chosenMedia variable so the code looks like this instead

@inherits umbraco.MacroEngines.DynamicNodeContext
@{ 
var  folderId = Model.GetPropertyValue("mediaFolder");

    var  chosenMedia  =  Model.MediaById(@folderId);

    if  (chosenMedia.NodeTypeAlias  ==  "Folder")
 {
     foreach  (var  img  in  chosenMedia.Children.OrderByDescending("Id"))
     {
         if  (img.NodeTypeAlias  ==  "Image")
         {                   
             <div>
                 Navn: @img.name
             <img  src="@img.umbracoFile" width="700px" />
                     </div>
         }
     }
 } 
}

Does that work?

In Umbraco version 7.2.1 assembly: 1.0.5462.37503 use:
```
.Children.OrderBy("createDate desc")
```
This does not work.
```
.Children.OrderByDescending("createDate")
```
