SPO custom action to hide delete button

Brass Contributor



I need, in a list, when select an item, to hide in the ribbon the delete button (at least); I've seen that maybe this is possible with a custom action and find powershell code to implement it, but it doesn't work; the code is this:


#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
#Set parameter values
$ListName ="MyList"
$Location = "Ribbon.ListItem.Manage.Delete"
$CustomActionTitle ="HideDeleteButton"
    #Get Credentials to connect
    $Cred= Get-Credential
    $Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)
    #Setup the context
    $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
    $Ctx.Credentials = $Credentials
    #Get the List
    #$List = $Ctx.Site.lists.GetByTitle($ListName)
    $List = $Ctx.Web.lists.GetByTitle($ListName)
    #Get Existing Custom Actions
    $UserCustomActions= $List.UserCustomActions
    #Check if the CustomAction Exists already
    $CustomAction = $UserCustomActions | Where { $_.Title -eq $CustomActionTitle }
    If($CustomAction -eq $Null)
        #Add new custom action
        $UserCustomAction = $List.UserCustomActions.Add()
        #Set the Properties of the custom action
        $UserCustomAction.Name = $CustomActionTitle
        $UserCustomAction.Title = $CustomActionTitle
        $UserCustomAction.Location = "CommandUI.Ribbon"
        $UserCustomAction.CommandUIExtension = "<CommandUIExtension><CommandUIDefinitions><CommandUIDefinition Location='$($Location)'/></CommandUIDefinitions></CommandUIExtension>"
        $UserCustomAction.Sequence = 1000
        $UserCustomAction.RegistrationType = "List" # On Web or Site Scope, Use these two properties
        $UserCustomAction.RegistrationId = 100
        Write-Host -f Green "Custom Action Added Successfully!"
         write-host -f Yellow "Custom Custom Already Exists!"
Catch {
        write-host -f Red "Error Adding Custom Action!" $_.Exception.Message


When I execute this, I obtain the error:


Eccezione durante la chiamata di "ExecuteQuery" con "0" argomento/i: "Setting this property is not supported.  A value of List has already been set and cannot be changed."
In riga:1 car:1
+ $Ctx.ExecuteQuery()
+ ~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : ServerException


The ExecuteQuery that give the error is that on the row 47 in the code; I don't know, also, if the $Location value is exact (I've taken it on Default Server Ribbon Customization Locations | Microsoft Docs).


Any help is appreciated.

@Marco Mangiante If you want to remove the delete button, you can also create a custom permission level (like Contribute without delete) and grant limited permissions to users.


Is there any other scenario/requirement where user need higher permissions on the same list/library?

thanks for your reply; I tried it but I have a drawback: in my list I created a custom column that host a link to a flow that cancel that particular row; now, if I set the permission like you suggested, when I click on the link the flow doesn't start..but it not only doesn't start, I haven't the form that appears on the right side of the list that let me run it.
