The latest version of the Survey module allows you to export the Survey results. This worked fine until DNN 4.7. Now it throws:

Sys.WebForms.PageRequestManagerParserErrorException

The problem is that even though it is not suppose to be in an ASP.NET AJAX Update Panel, now it is (I think this was due to a Core change to fix another issue). The solution was to indicate that the Export link will now cause a post back:

        Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            If DotNetNuke.Framework.AJAX.IsInstalled Then
                DotNetNuke.Framework.AJAX.RegisterScriptManager()
                DotNetNuke.Framework.AJAX.RegisterPostBackControl(lnkExport)
            End If
        End Sub

I should have this fix submitted to the release tracker in mid-December.
