I wonder if there is a way to create a Custom List in Sharepoint, but specify that each user may only create one item in the list.

I am thinking of two approaches:

  • Develop a ListReceiver that checks if the user already created an item. Problem: I did not see a way to enable a Feature on a specific list (the idea is that non-developers can just create a custom list and ‘switch on’ the Feature if they want
  • Create a Custom List Type, so when people click the ‘Create’ Button, they see ‘Custom Unique List’ under ‘Custom Lists’ as an additional type.

Before I do the second option, does anyone know if the first option is possible? Or even if it can already be done without custom development (and without a custom workflow in SPDesigner)

  1. Without custom code you are out of luck. You can easily add a receiver to a single list using code, just add the receiver to the SPListItem.EventReceivers collection as such:

    list.EventReceivers.Add(SPEventReceiverType.ItemAdded, ‘YOUR STRONG NAME’, ‘YOUR CLASS NAME’);

    There is no way directly through a feature elements file, however.

    If you want an option to enable or disable the feature on a particular list you can also add a CustomAction and bind it to that specific list template for instance so that an extra Action menu item allows Enable or Disable Unique Posts.
