How to remove event receivers in a SharePoint list?
Event receiver instances on a SharePoint list can be removed by either of the methods mentioned below.
#1. Using PowerShell:-
– Below is the Powershell script to get the list of all event receivers present on a list.
Add-PSSnapin Microsoft.SharePoint.PowerShell –erroraction SilentlyContinue
$web = Get-SPWeb -Identity <<Site URL>>
$list = $web.Lists[“<<List Name>>”]
$list.EventReceivers
** replace <<Site URL>> , <<List Name>> place holders in the script as needed.
This will get all the event receivers with their properties (Id, Name etc.) present on this list.
– Identify the Id or Name of the event receiver which should be deleted. Run below PowerShell script to delete a event receiver using Id of an event receiver.
Add-PSSnapin Microsoft.SharePoint.PowerShell –erroraction SilentlyContinue
$web = Get-SPWeb -Identity <<Site URL>>
$list = $web.Lists[“<<List Name>>”]
$type = "<<Event receiver type>>"
$receiverId = "<<Event receiver Id>>"
# replace <<Event receiver type>> with event type. eg: ItemDeleting, ItemAdding, ItemUpdating etc.
# replace <<Event receiver Id>> with the id of event receiver.
$numberOfEventReceivers = $list.EventReceivers.Count
if ($numberOfEventReceivers -gt 0)
{
for( $index = $numberOfEventReceivers -1; $index -gt -1; $index–-)
{
$receiver = $list.EventReceivers[$index] ;
$name = $receiver.Name;
$id = $receiver.Id;
if ($id -eq $receiverId) #similary ($name -eq "event receiver’s name") can be used.
{
$receiver.Delete()
Write-Host "Event receiver " $name " is deleted"
}
}
}
else
{
Write-Host " There is no EventReceivers with Id " $receiverId" registered for this list "
}
$web.Dispose()
#2. Using SharePoint Manager tool:-
