Maximize List Items In SharePoint

A SharePoint tutorial by Peter Kalmstrom

In this tutorial Peter Kalmstrom, CEO of kalmstrom.com Business Solutions and Microsoft certified SharePoint specialist and trainer, shows an easy way to maximize the number of items in a SharePoint list. When someone tries to add an additional item a message will be show and no item can be added.

This method is useful when you want users to be able to edit list items but not add new ones, as this cannot be achieved with SharePoint permissions.

Peter is using SharePoint 2013 for this demonstration, but his method for maximizing the number of list items works equally well in SharePoint 2010.

These are the steps:

Create a list with the maximum number of items.
Set the validation for new items to something that can never be true. Peter uses a created day for new items that is before the list creation date.
Write a message to be show when someone tries to book a new item in the list.
