I have few forms through out the software that have the same behavior in terms of the issue. It happens on my machine (development environment) and all the other machines that software have been installed.
All the forms have to ribbon that is working and displaying all the features absolutey fine, once it opened. When the form is been minimized and opened again, top ribbon is gone. Only white blank square is displayed where the ribbon suppose to be.
I tried to click or drag on the white blank area, but nothing happens.
I am developing software with VB.NET 2012 using Infragistics 12.1 on Windows 8 machine.
Is this a bug in the ribbon? We are working with Infragistics for a long time now and we never had this issue. It started to happen recently. Any thoughts?
Yep, I was just able to reproduce with other themes, unfortunately.
I guess I'll need to implement your workaround while Infragistics fixes this issue, thanks for sharing!
This problem seems to occur in my project with any theme.
I am also experiencing the same problem: minimizing then restore the window and the Ribbon is blank.
It seems to happen only when using the Windows 7 Basic theme, if I change the theme to one using Aero, the problem goes away.
Hello,
Thank you for your feedback. Please let me know if this issue occurs once more and you are able to identify the steps to reproduce it, I will be glad to assist you.
Unfortunately I can't reproduce the error with an empty form and ribbon and I can't upload the project for number of reasons.
I did managed to get around the problem.
On Form_Resize event I forced the ribbon to minimize and maximize. Once form is brought back on the screen ribbon is displayed.
