I encounter such a problem. I want to implement:
If condition A is satisfied(such as button1 is clicked), I want to use Restore icon to cover the maximize icon on the toolbar(The form is not maximized,I know if I click the maximize icon, the resotre icon will appear. I want the form size is not change).
If condition B is satisfied, the Restore icon will disappear.
Do you have any ideas? Could you please help me? Thanks.
