Temporarily disable Sitecore client notifications to suppress unwanted new-item redirects

The default behavior, when a user kicks off any action in the Sitecore client which adds a new item, is that the client redirects to the newly created item. In some (many) cases this may be desirable, but in others it is an unwanted side effect.

In order to suppress this behavior, two approaches may be helpful. One sometimes recommended is to suppress all events while creating the new item, but this should be done with caution depending on the environment. To do this enclose the item-creation code in a using statement like this one:

using (new Sitecore.Data.Events.EventDisabler()
// item creation code here...

Even better, and an approach which should be sufficient by itself, is to suppress client notifications during the item creation, like so:

Sitecore.Client.Site.Notifications.Disabled = true;
// item creation code here...
Sitecore.Client.Site.Notifications.Disabled = false;

To be safe, be sure to re-enable client notifications in the finally of a try-catch block. Also, depending on the Sitecore version, bucketable items may need a special tweak to suppress notifications as well.
