Update a DynamicContent item of a dynamic module in Sitefinity - sitefinity

Question

I am trying to update a DynamicContent Property of a module using the following:
DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager();
Type pollanswerType = TypeResolutionService.ResolveType("Telerik.Sitefinity.DynamicTypes.Model.Poll.Pollanswer");
Guid pollanswerID = new Guid(answerID);
// This is how we get the pollanswer item by ID
DynamicContent pollanswerItem = dynamicModuleManager.GetDataItem(pollanswerType, pollanswerID);
pollanswerItem.SetValue("VoteCount", int.Parse(pollanswerItem.GetValue("VoteCount").ToString()) + 1);
dynamicModuleManager.SaveChanges();
Basically getting the current Property value and incrementing it by 1
and calling SaveChanges()
the code runs without errors but it doesn't update the value when I check it from the Back End of Sitefinity.
Any suggestions?

Answer 1

The problem might be caused by the pollanswerID that you are passing.
If the pollanswerID is the id of the live version of the content item then the value wouldn't be set.
Make sure you set the field value to the of master version of the content type not the live one.
In case you don't know the id of the master version of the content type you can get the master content item by the id of the live version of the content type
var masterItem = dynamicModuleManager.GetDataItems(pollanswerType).Where(dynItem => dynItem.Id == pollanswerItem.OriginalContentId).FirstOrDefault();
if (masterItem != null)
{
masterItem.SetValue("VoteCount", int.Parse(masterItem.GetValue("VoteCount").ToString()) + 5);
}

Answer 2

you should be always doing this
Get Master
Checkout Master
Checkin Master
Save Changes
Publish changes – this will update live.
bookingItemLive is the live record
var bookingItemMaster = dynamicModuleManager.Lifecycle.Edit(bookingItemLive) as DynamicContent;
//Check out the master to get a temp version.
DynamicContent bookingItemTemp = dynamicModuleManager.Lifecycle.CheckOut(bookingItemMaster) as DynamicContent;
//Make the modifications to the temp version.
bookingItemTemp.SetValue("CleanerId", cleanerId);
bookingItemTemp.SetValue("SubCleanerId", subCleanerId);
bookingItemTemp.LastModified = DateTime.UtcNow;
//Checkin the temp and get the updated master version.
//After the check in the temp version is deleted.
bookingItemMaster = dynamicModuleManager.Lifecycle.CheckIn(bookingItemTemp) as DynamicContent;
dynamicModuleManager.SaveChanges();
//Publish the item now
ILifecycleDataItem publishedBookingItem = dynamicModuleManager.Lifecycle.Publish(bookingItemMaster);
bookingItemMaster.SetWorkflowStatus(dynamicModuleManager.Provider.ApplicationName, "Published");

#Joseph Ghassan: You can follow below step.
Step 1: Get Live
var bookingItemLive= manager.GetDataItem(ModuleType, GuidId);
Step 2: Get Master
var bookingItemMaster = manager.Lifecycle.GetMaster(bookingItemLive) as DynamicContent;
Step 2: Checkout Master --> will be created a draft item( you will update data by draft)
if (bookingItemMaster == null)
{
return new HttpResponseMessage
{
Content = new JsonContent(new { Result = false })
};
}
var bookingItemDraff = manager.Lifecycle.CheckOut(bookingItemMaster) as DynamicContent;
//Make the modifications to the temp version.
bookingItemDraff.SetValue("CleanerId", cleanerId);
bookingItemDraff.SetValue("SubCleanerId", subCleanerId);
bookingItemDraff.LastModified = DateTime.UtcNow;
Step 3: Checkin Master
// Now we need to check in, so the changes apply
var checkInItem = manager.Lifecycle.CheckIn(bookingItemDraff);
Step 4: Publish changes
manager.Lifecycle.Publish(checkInItem);
Step 5: Save Changes - this will save to Database and update live.
bookingItemDraff.SetWorkflowStatus(manager.Provider.ApplicationName, CustomFieldName.PublishedStatus);
manager.SaveChanges();
