Two ways of Changing an Asynchronous Eventhandler to Synchronous Eventhandler in lists Sharepoint 2010

Hi we can Change an Asynchronous Eventhandler to Synchronous Eventhandler in lists Sharepoint 2010 in two ways to avoid save conflict error.

First method:

In the elements.xml file just change the name of list and add synchronous tag

<Elements xmlns=”http://schemas.microsoft.com/sharepoint/“>
<Receivers ListUrl=”ListName”>
<Receiver>
<Name>EventReceiver1ItemAdded</Name>
<Type>ItemAdded</Type>
<Assembly>$SharePoint.Project.AssemblyFullName$</Assembly>
<Class>EventReceiverProject1.EventReceiver1.EventReceiver1</Class>
<SequenceNumber>1000</SequenceNumber>
<Synchronization>Synchronous</Synchronization>

</Receiver>
</Receivers>
</Elements>

Second method:

//Create an Empty Eventhandler

 SPEventReceiverDefinition itemAddedEventRec = lstname.EventReceivers.Add();

itemAddedEventRec.Name = “AddItem”;

//Change to Synchronous

itemAddedEventRec.Synchronization = SPEventReceiverSynchronization.Synchronous;

itemAddedEventRec.Type = SPEventReceiverType.ItemAdded;

itemAddedEventRec.Assembly = “Assembly Name”;

itemAddedEventRec.Class = “ClassName”;

itemAddedEventRec.Update();

lstname.Update();
