I've just installed DevExpress 8.1.1 and used their Project Convertor to change the Inherited UI reference. I opened the Inherited UI solution to recompile as had the nine errors - all the same and following is a sample

       Private Sub AddBrowseResultsList()
            '-- Establish Locals
            Dim loPanel As Panel = Nothing

            '-- Determine which panel will house the browse results
            With _BrowseDialog.FormLayout
                '-- Get the panel where the listview will reside
                If .TopPanelContents = BrowseDialogLayoutType.BrowseResults Then
                    loPanel = LeftSplit.Panel1 <<<<<<<< ERROR
                ElseIf .BottomPanelContents = BrowseDialogLayoutType.BrowseResults Then
                    loPanel = LeftSplit.Panel2 <<<<<<<< ERROR
                ElseIf .SidePanelContents = BrowseDialogLayoutType.BrowseResults Then
                    loPanel = MainSplit.Panel2 <<<<<<<< ERROR
                End If
            End With

Error message:
Error 2 Value of type 'DevExpress.XtraEditors.SplitGroupPanel' cannot be converted to 'System.Windows.Forms.Panel'. C:\Program Files\MicroFour\StrataFrame Source Code\MicroFour StrataFrame Inherited UI\DevExpress Extended\Dialogs\browsedialogwindow.vb 634 31 MicroFour StrataFrame Inherited UI

I removed the 8.1.1 reference and reapplied and the problem remained.

I changed the reference back to 7.3.8 and all was ok.

Has anyone successfully migrated to 8.1.1?

Cheers, Peter
