Hi I would like to know how I can breakRoleInheritance for a list item using Powershell. Please see below. Thanks in advance.

$mysitename = "http://xxx.com/"
$web = get-spweb -identity $mysitename # Get the site collection
$list = $web.Lists["mylist"]

$item =$list["myfile.xml"] ?????

$item.BreakRoleInheritance($false)

Hi wkpli，

I have done a test again in SharePoint 2010 and I reproduced the issue.

The command $Item.BreakRoleInheritance($true) is working in SharePoint 2013 while not working in SharePoint 2010.

You said that "used C# instead Powershell and the BreakRoleInheritance works", have you successfully stop inheriting permissions from list items in SharePoint 2010?

Check the following PowerShell:

You would simply run:

$web = Get-SPWeb http://webUrl
$list = $web.Lists["List_Title"]
$item = $list.Items[Item_Index] #or however you want to get it
$item.BreakRoleInheritance($false) #or $true to copy permissions

Thanks, how can I get the item_index?

Probably an easier way to do this:

$item = $list.GetItems("Title of item")

Trevor, I tried what you suggested, but I got the following error when I run BreakRoleInteritance. Please advice.

$item = $list.GetItems("Title of item")

$item.BreakRoleInheritance($false)

Error:

Method invocation failed because [Microsoft.SharePoint.SPListItemCollection] doesn't contain a method named 'BreakRoleInheritance'.
At line:1 char:27

$item.BreakRoleInheritance <<<< ($false)

Hi,

Per my test, the following command is working:

$web = Get-SPWeb http://webUrl
$list = $web.Lists["List_Title"]
$item = $list.GetItems("Item Title")
$item.BreakRoleInheritance($true)

eg:

$web = Get-SPWeb "http://sp"
$list = $web.Lists["ct1"]
$item = $list.GetItems("aa")
$Item.BreakRoleInheritance($true)

Best Regards,

Lisa Chen

I copied exactly what you have except I have "$false" instead of "$true", but I still get the same error message.

I used C# instead Powershell and the BreakRoleInheritance works. Any idea?

Thanks in advance.

You are trying to use a filename to get a list item. But there is a difference between the SPListItem object and the SPFile object. Try to get the list item with the URL, using the SPWeb.GetListItem method.

$filename = "myfile.xml"

$listname = "myList"

$url = $web.serverrelativeurl + "/" + $listname + "/" + $filename
$web.GetListItem($url)

If there are subfolders you will need to adjust but, this will give you the list item based on the file name.

Hi wkpli,

I can't reproduce your issue.

$web = Get-SPWeb http://webUrl
$list = $web.Lists["List_Title"]
$item = $list.GetItems("Item Title")
$item.BreakRoleInheritance($true)

1. Change the http://webUrl to the url of your site.

2. Change the "List_Title" to the title of your list.

3. Change the "Item Title" to the title of a item in the list.

4. You can use both "$true" or "false".

eg: I have a site: "http://sp" which contains a list named "ct2", there is a item which is "aa", I run the following command, the "aa" will stop inheriting permissions from the "ct2":

If the issue still exists, Please offer a screenshot about your list and the command in SharePoint 2013 Management Shell.

Best Regards,

Lisa Chen
