Handling an adding new item event in dynamic module

I've created new dynamic module with Module Builder (for example Products). I would like to do some actions when I add new item to content Products. Is it possible to handle that event?

I will be very grateful to someone who will help with suggestions.

Hi,

Yes this is possible by subscribing to the lifecycle events of the content modules. The approach is to create a custom decorator as described in this KB article. The approach is to have a separate decorator for each module you want to handle lifecycle events like publish, modify (delete is a separate topic). The decorator attaches to an event, for example publish.
When we talk about a custom decorator that will handle dynamic content (module builder) you have to change the registration of the decorator in Global.asax. This is necessary because in Dynamic modules the items you create are not inheriting from content and while all other modules (news, blogs, events), register a decorator that will handle content

new InjectionParameter<Action<Content, Content>>(null),
Dynamic modules register the decorator like this:
protected void Application_Start(object sender, EventArgs e)
       
           Bootstrapper.Initialized += new EventHandler<Telerik.Sitefinity.Data.ExecutedEventArgs>(Bootstrapper_Initialized);
       
   
       void Bootstrapper_Initialized(object sender, Telerik.Sitefinity.Data.ExecutedEventArgs e)
       
   
           if (e.CommandName == "Bootstrapped")
           
               ObjectFactory.Container.RegisterType<ILifecycleDecorator, CustomDecorator.NewsDecorator>
                   (typeof(DynamicModuleManager).FullName,
                       new InjectionConstructor(
                           new InjectionParameter<ILifecycleManager>(null),
                           new InjectionParameter<LifecycleItemCopyDelegate>(null),
                           new InjectionParameter<Type[]>(null)
                           )
                   );
           
       

For the module builder each item you create regardless of the naming of your module it is considered DynamicContent so in the decorator register the item you will be working with like this

I realize you will need to work with a lot of different modules with the module builder and creating new decorator for each separate module will not be possible so specify the type of module you will be executing something on publish like this.
DynamicContent dynamicContent = item as DynamicContent;
            string dynamicContentType = dynamicContent.GetType().FullName;
if (dynamicContentType.Equals(TesetingModules.TestModule.FullName))
 
// execute logic for one module called TestingModule
.. add another module logic below

Hi,
I created a decorator for a dynamic module using the code you ve provided and also the kb.
But I get this error in the global.asax file
CS0308: The non-generic method 'Telerik.Microsoft.Practices.Unity.IUnityContainer.RegisterType(System.Type, System.Type, string, Telerik.Microsoft.Practices.Unity.LifetimeManager, params Telerik.Microsoft.Practices.Unity.InjectionMember[])' cannot be used with type arguments

This is my complete global.asax file:
<%@ Application Language="C#" %>
 
<script runat="server">
 
    void Application_Start(object sender, EventArgs e)
    
        // Code that runs on application startup
        Telerik.Sitefinity.Abstractions.Bootstrapper.Initialized += new EventHandler<Telerik.Sitefinity.Data.ExecutedEventArgs>(Bootstrapper_Initialized);
    
     
    void Bootstrapper_Initialized(object sender, Telerik.Sitefinity.Data.ExecutedEventArgs e)
    
 
        if (e.CommandName == "Bootstrapped")
        
            Telerik.Sitefinity.Abstractions.ObjectFactory.Container.RegisterType<Telerik.Sitefinity.Lifecycle.ILifecycleDecorator, CustomDecorator.DynamicModulesDecorator>
                (typeof(Telerik.Sitefinity.DynamicModules.DynamicModuleManager).FullName,
                    new Telerik.Microsoft.Practices.Unity.InjectionConstructor(
                        new Telerik.Microsoft.Practices.Unity.InjectionParameter<Telerik.Sitefinity.Lifecycle.ILifecycleManager>(null),
                        new Telerik.Microsoft.Practices.Unity.InjectionParameter<Telerik.Sitefinity.Lifecycle.LifecycleItemCopyDelegate>(null),
                        new Telerik.Microsoft.Practices.Unity.InjectionParameter<Type[]>(null)
                        )
                );
        
    
     
    void Application_End(object sender, EventArgs e)
    
        //  Code that runs on application shutdown
 
    
         
    void Application_Error(object sender, EventArgs e)
    
        // Code that runs when an unhandled error occurs
 
    
 
    void Session_Start(object sender, EventArgs e)
    
        // Code that runs when a new session is started
 
    
 
    void Session_End(object sender, EventArgs e)
    
        // Code that runs when a session ends.
        // Note: The Session_End event is raised only when the sessionstate mode
        // is set to InProc in the Web.config file. If session mode is set to StateServer
        // or SQLServer, the event is not raised.
 
    
        
</script>


UPDATE:

For anyone else who is also getting the same error, you need to include the below in your Global.asax file:
<%@ Import Namespace="Telerik.Microsoft.Practices.Unity" %>

Thank you!  I knew there had to be some missing import with an extension method somewhere but couldn't find it until I found this post.
