Recently
there was a need to update documents/ list items without creating new version
and updating 'Modified' and 'Modified by' values. Lists and Libraries
were having event receivers or workflows. There are couple of options to
update SPListItem and need to understand the differences between
them.
Update()
·
Updates the item in
the database.
·
Updates the 'Modified'
and 'Modified by' values.
·
Creates a new version
Systemupdate()
·
Updates the item in
the database.
·
No changes in
the 'Modified' and 'Modified by' values.
·
No new version.
·
Triggers the item
events.
Systemupdate(true)
·
Same as Systemupdate()
and it increments item version.
·
Using
SystemUpdate(false) is same as SystemUpdate().
UpdateOverwriteVersion()
·
Updates the item but
does not create a new version.
·
Updates the 'Modified'
and 'Modified by' values.
you
could set EventFiringEnabled = false to disable the triggering of events
(workflows). Set EventFiringEnabled = true after item update to
enable the events again.
