Just noticed you can also drop the line with the private _listId variable too because I used the declarative getter/setter for that one, no need for the private property in that case

Just refer to the list you need as SPContext.Current.Web.Lists[ListId] and you should be fine.

I think I'm half way there. I've added a new private string for listID and a new property for ListID. I've attempted to modify the get/set part of the ListName property as you suggested but not sure if I'm on the right track. Any assistance is greatly appreciated!

Have the setter property for ListName store the GUID into a hidden property (still a public property, but without the web editable attribute) so that the user still just chooses a list name, and then change the getter for the property to look up the list name and return the string. Then you can rename the lists in the UI as much as you like, but because you are only ever working with the ID for it internally things shouldn't break Brian Farnhill Solutions Architect, Extelligent Design | SharePoint Server MVP phone: 0408 289 303 | twitter: <http://twitter.com/BrianFarnhill> @BrianFarnhill | blog: <http://blog.brianfarnhill.com/> blog.brianfarnhill.com | xbox: <http://live.xbox.com/en-AU/MyXbox/Profile?Gamertag=Modern%20Bogan> Modern Bogan From: ozmoss-boun...@ozmoss.com [mailto:ozmoss-boun...@ozmoss.com] On Behalf Of Paul Noone Sent: Monday, 6 February 2012 11:58 AM To: ozMOSS (ozmoss@ozmoss.com) Subject: Auto-update webpart property when object renamed Hi all, Is there a way to auto-update wp properties (such as list name) when the object is renamed? I know SharePoint manages to do this with Summary Links wp and the PageContent placeholder. Kind regards, Paul
