Hello.

I've a grid that is edited through an UltraGridRowEditTemplate and in the Click of the "Ok" button I'm making some validations. If something fails I show a message box. The grid is into a form which is an MdiChild managed by an UltraTabbedMdiManager. When the click event calls the method Close of the UltraGridRowEditTemplate after the message box has been shown, it will fire a change of tab in the UltraTabbedMdiManager.

I know this sounds too rare and even hard to understand so I'm attaching a small project to reproduce this issue.

Please help Infragistics Community! It's driving me crazy!
