Ahh very tricky :). Found a subtle bug in my code. But yes, thank you Helen, that did the trick!

Is it possible that the current user is not authenticated? Are you using Forms or Windows auth? Can you check the values of Page.User.Identity.IsAuthenticated and Page.User.Identity.Name? When the current user is not authenticated, the Personalization scope will be defaulted to "Shared" and the current user does not have the permission to modify personalization state.

Hope that helps.

Trouble moving web parts from one zone to another.

Hi. I'm sorry to post such a vague question, but I hope someone can at least tell me where to start looking to narrow down the problem I'm having.

I have code that moves a web part on a post back. It used to work before so I'm not sure where the regression is (or if something changed in the .NET framework with the RC0 release), but I'm getting the following stack trace when I call WebPartManager.MoveWebPart():

[InvalidOperationException: Personalization is not enabled and/or modifiable. The Enabled property must be set to true, and a registered personalization provider must be selected. The current user must be granted the right to modify personalization state.]

   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +172
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +4921

Version Information: Microsoft .NET Framework Version:2.0.50727.26; ASP.NET Version:2.0.50727.26

I've tried manually connecting to the personalization database with an SqlConnection object using the query string that the Personalization provider is using, and I can insert records into that database with an SqlCommand object. This would indicate to me that there aren't any problems actually connecting to the database.

When I look at the WebPartManager.Provider object in the debugger, it's set to "Shared" scope. Now in my code I set the WebPartManager.InitialScope to "User", but somewhere it gets changed. I don't have any code in my project where I set it to "Shared", so how would it be reverting back to "Shared"?

What else can I look for to see where this is going wrong? What else could I be forgetting that I need to enable for web parts personalization to work?

Thanks for any help!
