Get Renderings for page currently being edited

Question

I'm trying to get the renderings of the current item being edited. So, when components are added to a placeholder in the Experience Editor, I want to be able to get those renderings.

If I use Context.Item.Visualization.GetRenderings, this obviously gets the renderings of the context item, but it's the saved item, not the one that's currently being edited.

I'm wondering if there's any way to either get the current edit item, or if there's a pipeline that I can intercept what has currently beeing added.

If you want to get that information when you're saving an item, you can add your own processor to item:saving event.

public class MyHandler
{
  protected void OnItemSaving(object sender, EventArgs args)
  {
    Item newItem = Event.ExtractParameter(args, 0) as Item;

    if (newItem == null || newItem.Database.DataManager.GetWorkflowInfo(newItem) == null)
    {
      return;
    }

    Item originalItem =
      newItem.Database.GetItem(newItem.ID, newItem.Language, newItem.Version);
      
    var newItemRenderings = newItem.Visualization.GetRenderings(Context.Device, false);
    var originalItemRenderings = originalItem.Visualization.GetRenderings(Context.Device, false);
    
    // your code to compare newItemRenderings with originalItemRenderings
  }
}

Remember to register your processor:

<sitecore>
  <events>
    <event name="item:saving">
      <handler type="My.Assembly.Namespace.MyHandler,
        My.Assembly" method="OnItemSaving" />
    </event>
  </events>
</sitecore>

You can get the current item rendering through this code :-

Sitecore.Data.Database master = Sitecore.Configuration.Factory.GetDatabase("master");
Sitecore.Data.Items.Item currentItem = master.GetItem("<path of your item>");

RenderingReference[] renderings = currentItem.Visualization.GetRenderings(Context.Device, false);

foreach (RenderingReference rendering in renderings)
{
<your code>
}

You can use Context.Database.Name to get the database name dynamically.

Hope this helps!!

I would say that there are some events that you can identify when you see the ShowConfig

https://yoursite/sitecore/admin/showconfig.aspx

These events are

<event name="item:added"/>
<event name="item:adding"/>

And you can check their config details also. You need to extract the DLLs of these events and you will get some logic that you can override and use your assembly in place of this.

Refer to this article for more details.

I hope this help.
