Enhancement Number
Cause
Due to the bug, the data cannot be retrieved when the item is updated.
Resolution

Capture the dirty items on the provider level and check there for the updated or created items and get the required information.

Subscribe to the Executing and Executed events of the provider:

void Bootstrapper_Initialized(object sender, Telerik.Sitefinity.Data.ExecutedEventArgs e)
       {
           if (e.CommandName == "Bootstrapped")
           {
                
               var provider = DynamicModuleManager.GetManager().Provider;
               provider.Executing += Provider_Executing;
               provider.Executed += provider_Executed;
           }
       }

 

In executing capture the dirty items and persist their ids:

 

private void Provider_Executing(object sender, Telerik.Sitefinity.Data.ExecutingEventArgs e)
       {
           if (!(e.CommandName == "CommitTransaction" || e.CommandName == "FlushTransaction"))
               return;
   
           var provider = sender as DynamicModuleDataProvider;
           if (provider == null)
           {
               return;
           }
   
           //Create separate containers for information coming from updated and craeted items
   
           HashSet<Guid> updatedItemsUrls = provider.GetExecutionStateData("DeletedItemUrls") as HashSet<Guid>;
           HashSet<Guid> createdItemsIds = new HashSet<Guid>();
   
           //Added a container for the item types to allow easy retrieval of the item and for it to work for all dynamic types
           HashSet<string> updatedItemType = new HashSet<string>();
           HashSet<string> cretedItemType = new HashSet<string>();
   
           if (updatedItemsUrls == null)
               updatedItemsUrls = new HashSet<Guid>();
   
           var dirtyItems = provider.GetDirtyItems();
   
           for (int i = 0; i < dirtyItems.Count; i++)
           {
               var item = dirtyItems[i] as DynamicContent;
               if (item == null)
                   continue;
   
               var itemStatus = provider.GetDirtyItemStatus(item);
               if (itemStatus == Telerik.Sitefinity.Security.SecurityConstants.TransactionActionType.Updated)
               {
                   updatedItemsUrls.Add(item.Id);
                   updatedItemType.Add(item.GetType().ToString());
               }
               else if (itemStatus == Telerik.Sitefinity.Security.SecurityConstants.TransactionActionType.New)
               {
                   createdItemsIds.Add(item.Id);
                   cretedItemType.Add(item.GetType().ToString());
               }
           }
   
           if (updatedItemsUrls.Count > 0)
           {
               provider.SetExecutionStateData("UpdatedItemId", updatedItemsUrls);
               provider.SetExecutionStateData("UpdatedItemType", updatedItemType);
               provider.SetExecutionStateData("CreatedItemIds", createdItemsIds);
               provider.SetExecutionStateData("CreatedItemType", cretedItemType);
           }
       }
in the executed event, we can get the ids and based on them get the RelatedData as needed
private void provider_Executed(object sender, Telerik.Sitefinity.Data.ExecutedEventArgs e)
        {
            if (e.CommandName != "CommitTransaction")
                return;
   
            var provider = sender as DynamicModuleDataProvider;
            if (provider == null)
            {
                return;
            }
   
            //Get the required information
            var updatedItem = provider.GetExecutionStateData("UpdatedItemId") as HashSet<Guid>;
            var updatedItemType = provider.GetExecutionStateData("UpdatedItemType") as HashSet<string>;
            var createdItem = provider.GetExecutionStateData("CreatedItemIds") as  HashSet<Guid>;
            var createdItemType = provider.GetExecutionStateData("CreatedItemType") as HashSet<string>;
   
            //I introduced the same logic separately depending on if the items is updated or created for the first time
            if (updatedItem != null)
            {
                foreach (var id1 in updatedItem)
                {
                    var id = id1;
                    var providerName = String.Empty;
   
                    DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager(providerName);
                       
                    Type questionType = TypeResolutionService.ResolveType(updatedItemType.FirstOrDefault());
                    var item = dynamicModuleManager.GetDataItem(questionType, id);
                    if (item.Status == Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Live)
                    {
                        //You can add different logic for the different dynamic types that you have.
                        if (item.GetType().ToString() == "Telerik.Sitefinity.DynamicTypes.Model.SleepyAdvisor.Question")
                        {
                            var relatedData = item.GetRelatedItems<DynamicContent>("Answers");
                        }
                    }
                }
