SharePoint / PowerShell List Item Update Note

 

Sometimes it's the forests and sometimes it's the trees…

 

I have gotten so used to using shortcuts like chaining of properties in PowerShell that I forget some of my .Net fundamentals.

The Title never gets updated in this little script. What's wrong?

$web = Get-SPWeb "http://maxsp2013wfe/sites/training"
$list = $web.Lists["Announcements"]
$list.items[3]["Title"]="Test Title"
$list.items[3].Update()

Line 3 creates a new SPListItem object in RAM and sets its Title property.
Line 4 creates a new (but different) SPListItem object and calls .Update() on it.

Duh!

 

This works:

$web = Get-SPWeb "http://maxsp2013wfe/sites/training"
$list = $web.Lists["Announcements"]
$item = $list.items[3]
$item["Title"]="Test Title"
$item.Update()

Create the SPListItem object once, change a property and then save it.

And I teach this stuff!
