Hi Grant and welcome to our :)

What version of Umbraco are you using?

I must admit that c# is not my best skill, but as far as I know it should be possible to use the umbraco.library extensions in C# as well, so even thought the example here http://our.umbraco.org/wiki/reference/umbracolibrary/getitem is based on XSLT you should be able to use umbraco.library:GetItem().

Hope this helps.

Thanks Jan, and for the welcome :) we've been using umbraco for a while but since we use sitecore too its been pretty easy so far, until I needed to find a way for users to embed video easily within a content page :)  

We are using umbraco 4.7.1.1

I tried modifying my getItem code to :

content = (umbracoItem.GetProperty("content");

content = umbraco.library.RenderMacroContent(content, umbracoItem.Id);

hoping that method would expand the macro, but didn't seem to work, but checking I did it correctly :)

Grant.

Hi Grant

Hmm, would it be possible for you to simply just use the umbraco:item on the masterpage to render the macro content? You should be able to have the content rendered by placing this in the template (Masterpage): <umbraco:Item field="content" runat="server" />

Hope this helps.

That doesn't render the macro, the code seems to be working now, its just not getting any parameters I set on the macro, but at least its being output so closer:)

Hmm, I'm all out of ideas then - but please share the solution with us once you find it :-)

Hi Grant,

The <umbraco:Item ... /> server control that Jan mentioned above should parse the macro tokens and render their output, but if you need to parse them yourself the following snippet might be useful:

using System.Text.RegularExpressions;
using System.Web.UI;
using System.Web.Text;
using System.IO;
using System.Xml;
using umbraco.presentation.templateControls;

namespace ExtensionMethods
{
  /// <summary>
  /// Parse a text string for any UMBRACO_MACRO tokens, and replace them with their rendered macros
  /// </summary>
  public static string ProcessUmbracoMacros(this string text)
  {
    bool macroFound;
    do
    {
      Match macroMatch = Regex.Match(text, @"<\?UMBRACO_MACRO .*macroAlias="".*"".*/>", RegexOptions.Singleline);
      macroFound = macroMatch.Success;

      if (macroFound)
      {
        XmlDocument xmlDocument = new XmlDocument();

        // remove the '?' char from the token so that can be treated as xml
        xmlDocument.LoadXml(macroMatch.Value.Remove(1, 1));

        XmlNode macroXmlNode = xmlDocument.SelectSingleNode("//UMBRACO_MACRO");

        Macro macro = new Macro();
        macro.Alias = macroXmlNode.Attributes["macroAlias"].Value;

        foreach (XmlAttribute attribute in macroXmlNode.Attributes)
        {
          if (attribute.Name != "macroAlias")
          {                         
            macro.MacroAttributes.Add(attribute.Name, attribute.Value);
          }                        
        }

        text = text.Remove(macroMatch.Index, macroMatch.Length);
        text = text.Insert(macroMatch.Index, macro.RenderToString());
      }
    }
    while (macroFound);
            
    return text;
  }

  /// <summary>
  /// Renders an ASP.NET control into a string
  /// </summary>
  public static string RenderToString(this Control control)
  {
    StringBuilder stringBuilder = new StringBuilder();
    StringWriter stringWriter = new StringWriter(stringBuilder);
    HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter);

    control.RenderControl(htmlTextWriter);

    return htmlTextWriter.InnerWriter.ToString();
  }
}

HTH,
