Cannot toggle personalization scope programmatically

Question

I'm trying to switch personalisation scope for the current user:

    protected void lnkToggleMode_Click(object sender, EventArgs e)
    {
        try
        {
            var wpmgr = (SPWebPartManager)SPWebPartManager.GetCurrentWebPartManager(this.Page);
            wpmgr.Personalization.ToggleScope();
        }
        catch (Exception)
        {
            throw;
        }
    }

However, the ToggleScope method throws this exception:

'wpmgr.Personalization.ToggleScope()' threw an exception of type 'System.Threading.ThreadAbortException' base {System.SystemException}: {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.} ExceptionState: Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.

Any thought?

FYI, the wpmgr.Personalization.CanEnterSharedScope property is returning true

From your question, I can't tell why you're not using an SPLimitedWebPartManager but the standard .net webpartmanager:

If you can get hold of either the SPWeb / SPFile object you're working on you could try calling mySPFileObject.GetLimitedWebPartManager which takes a personalizationScope enum as a parameter.
