First, 8.2 of the UltraWinTabbedMdi control does not support a visible property...hence my issue.
Even after I take that line of code out, save, compile it comes back.
this.uTab.Visible = true;
Why is this happening?
I'm not sure how this is happening but it is a bug and I would recommend submitting it to the support group: http://ko.infragistics.com/gethelp. As a workaround, try closing the forms designer and then remove the line that sets the Visible property. Perform a save all, then close all windows and rebuild the project. That should prevent the line from being re-added to the designer code.
