Creating Functions in C# Code Fragments aka C# TBB

Most of us are comfortable with writing  just a few bunch of code lines in a C# TBB. Ever thought of writing functions in a C# TBB ? And wonder how to call these functions…

Let’s get Movin’…

  1. Use the syntax <%!  %>  for defining functions inside the TBB.
  2. You can define any number of functions as you like and call them.
<%@ Import Namespace="Tridion.ContentManager.ContentManagement.Fields"%>

string test ="Hello_From_C# TBB";
package.PushItem("Hello_C# TBB", package.CreateStringItem(ContentType.Text,test));



private void PushWelcomeMessageToPackage()
   package.PushItem("Hello_From_Function_1", package.CreateStringItem(ContentType.Text,                                                                     "Got It"));
private void ProcessComponent()
   Item compItem= package.GetByType(ContentType.Component);
   Component component = engine.GetObject(compItem.GetAsSource().GetValue("ID")) 
                         as Component;
ItemFields componentFields = new ItemFields(component.Content, component.Schema);

if (componentFields.Contains("BrandTitle"))
         TextField title= componentFields["BrandTitle"] as TextField; 
         package.PushItem("BrandTitle", package.CreateStringItem(ContentType.Text, 


Run the Above TBB with any component and below are the results:

  1. Thanks for sharing, but what would be the advantage of the C# TBB with C# Code fragment like this then the one that need to be compiled


    1. So you are asking about advantages of a C#TBB over the Compiled one ( .NET Assemblies etc..).

      I strongly recommend you to read this blog post: by Albert te Boekhorst. This post gives an excellent insight into the Pros and Cons of .NET Templating and very clearly outlines the reasons to prefer .NET Templating (over TBBs of course).

      And thank you for your time to read my article and improving it further through questions.
