A further question to the second approach:

If I embed the MainForm into a UserControl, would the tabbed mdi manager work?

Thanks.
Mike

Is there a replacement for the mdi tabbing inside Infragistics that could be used in a UserControl?

Thanks

Do you have a simple sample of UltraTabControl to do that? 

I looked at some code for Windows TabContorl, but they are slightly different from UltraTabContro.

Thanks.

I don't think there is any sample which saves and loads the tab order, but you could do it with the SaveTabOrderAsBinary, SaveTabOrderAsXml, LoadTabOrderFromBinary, and LoadTabOrderFromXml methods.

Mike Dour"] you could do it with the SaveTabOrderAsBinary, SaveTabOrderAsXml, LoadTabOrderFromBinary, and LoadTabOrderFromXml methods.

Tried those method, but save is fine, but load does not create the tabs.

I may need to create my own serialization/deserialization methods.

BTW, I found the way to set the close button and reorder tabs by dragging.

Thanks.

To save the contents of each tab, can I use SerializeTag and DeserializeTag?

Thanks.

Yes, that is correct, the VisibleTabs collection will be in the same order as seen on screen.

I presume i can iterate throught the VisiableTabs collection instead of Tabs collection.

Mike Dour"]The load methods are not supposed to create the tabs, they just reorder the tabs to a previously saved tab order.

I see.

Is there a convenient way to iterate through the tabs collection via each tab's VisibleIndex instead of Index?

If I can do that, I do not need to save the tab order, just the contents to re-create the tab page.

Thanks.
