Hi,
Thank you for posting in our forums!
As far as I understand you want to customize the tooltip of Minimize and Maximize buttons of the main form. The FormManager enables you to style the area of a form such as the caption area, form borders and the close, restore maximize, minimize and context help buttons via setting different form style settings and appearances.
The buttons you refer are Microsoft’s standard control box buttons and therefore customization as changing the tooltip’s text is going to take a lot of effort and writing unmanaged code, because you can’t get directly none of the instances of these buttons, the Form Manager doesn’t support this sort of customization yet.
On the other hand Microsoft’s native controls, resolve their default tooltip values, based on the operating system current language settings. That’s said, localizing these tooltips is done by the operating system and your localization responsibilities are only left for the custom controls in your application.
Please let me know if you need further assistance on this matter.
