Probabbly i am not sure what to search for ... But the idea is to display a message bar bellow ribbon control. When user try to edit a read only file. I don't want user to click on OK to remove error message. Thats why i can't use MessageBox.
Status bar doesn't seem right place to display error messages.
Which control i should start exploring.
MSOffice normally displays such message when user opens files in protected view .
I don't want you to do research for me, I just want the right direction i will do the rest.
Thanks
