Does anyone have any related links razor working with a macro for Umbraco 7?

I unfortunately need to use the macro in the RTE and pass a parameter so can't use MVC, this just keeps throwing erros:

@inherits umbraco.MacroEngines.DynamicNodeContext
@using Newtonsoft.Json.Linq


@{
    var startNodeID = Parameter.ChooseButtonGroup;
}

@if (startNodeID != null)
{
    @* Get the start node as a dynamic node *@
    <h1>@startNodeID</h1>
    var startNode = Library.NodeById(startNodeID);
    
   foreach(var relatedLink in startNode.GetPropertyValue<JArray>("relatedLinks")) {
        
      <h1>@(relatedLink.Value<string>("title"))</h1>
      
  }
}

The error I'm getting is "'char' does not contain a definition for 'Value'"

Hi Amir,

Since v4.10 Partial View Macros have been the recommended macros for WebForms templates and Razor Macros are legacy. So you could use either of the snippets from here in a Partial View Macro

Hi Jeavon, I can't seem to access any of the properties in the datatype via razor. Shouldn't just "@item.Caption" return the value in the caption field? The json looks like this:

[{
   "caption":"Link1",
    "link":"http://google.com",
   "newWindow":false,
    "edit":false,
 "isInternal":false,
   "type":"external",
    "title":"Link1"
},{
  "caption":"Link2",
    "link":"http://google.com",
   "newWindow":false,
    "edit":false,
 "isInternal":false,
   "type":"external",
    "title":"Link2"
},{
  "caption":"Link3",
    "link":"http://google.com",
   "newWindow":false,
    "edit":false,
 "isInternal":false,
   "type":"external",
    "title":"Link3"
}]

Incase anyone else has this issue:

<ul>
                   @foreach (dynamic item in JsonConvert.DeserializeObject(startNode.GetPropertyValue<string>("relatedLinks")))
                    {
                     
                  var linkUrl = (bool)item.isInternal ? Library.NodeById(@item.link).Url : item.link;
                   var linkTarget = (bool)item.newWindow ? "_blank" : null;
                  <li><a href="@linkUrl" target="@linkTarget">@item.caption</a></li>
                        
                  }
             </ul>

Even simpler now in Umbraco 7.1.6

    @foreach (var link in CurrentPage.listOfLinks)
    {
        var linkTarget = (bool) link.newWindow ? "target=\"_blank\"" : "";
        <a href="@link.link" @Html.Raw(linkTarget)>@link.caption</a>
    }

@Jules I'm using v.7.4.3 and your solution doesn't work, I get Amir's original error. For some reason umbraco is returning the "CurrentPage.listOfLinks" value as a json string, which causes the loop to go char by char.

OK this is really, really strange. The type of the property value changed suddenly from a string to the typed object... magically. I have no idea what caused this behaviour.

At the top of the view:

var linksCollection = JsonConvert.DeserializeObject(Model.GetPropertyValue<string>("Links"));

in the html. in my case a loop that writes out <li></li> :

@if (linksCollection != null)
{
    <aside class="widget widget-recent-posts animate-up">
        <h2 class="widget-title">Links &amp; Documents</h2>
        <ul>
            @foreach (dynamic item in (IEnumerable<dynamic>) linksCollection)
            {
                var lnk = Json.Decode(item.ToString());
                var linkTarget = (bool) lnk.newWindow ? "target=\"_blank\"" : "";
                <li><a href="@lnk.link" @Html.Raw(linkTarget)>@lnk.caption</a></li>
            }
        </ul>
    </aside>

}

I am sure there could be some cleanup of the code, but it works....
