How to Prevent SharePoint List or Columns from Deletion?

Scenario: We have a configuration list being used by a custom SharePoint application, and we don’t want to let the users delete the configuration list in SharePoint. So how to prevent delete in SharePoint list?

The idea is: Set the “AllowDeletion” property of the SharePoint list or Library to false. These properties can be set programmatically using object mode code C# or PowerShell.

PowerShell script to Disable Delete on SharePoint List or Library:

#Get the Web
$web = Get-SPWeb ""

#Get the List
$list = $web.Lists["Design Documents"]

#Set the "AllowDeletion" property

“Delete this document library” or “Delete this list” link will go hidden under list settings!

       list.AllowDeletion = false;

Same trick applies to SharePoint list columns as well. Sett the field’s “AllowDeletion” property to false to prevent the field from deletion. Here is an example: Typical SharePoint list columns will look like:
