MDI defect with ControlBox property set false

[Guest]

I have an MDI application that uses several different classes of derived child forms. One derived child form class has its ControlBox property set to false at design time. It correctly displays in the MDI client area without any control boxes in the title bar (no minimize, no maximize and no close buttons).

However, if I double-click on the child form's title bar, it does the maximize behavior. The form now fills the entire MDI client area. It now also has control boxes!! And the control boxes remain if I click on the restore-size button!! So now my design-time choice of not offering control boxes has been undone!

Is this a defect?

Is it possible to prevent the double-click in the title bar from maximizing the child form?

Thanks,
Dave

Hi Babel,

From my understanding ,you need a MDI window which it could not be
maximized, minimized, and there is no system menu on it.
Beside setting ControlBox to false, You may also set the MaximizeBox
property of the MDI Form to false.
Does it solve your problem?

Set the MaximizeBox property of the child form to false. This will disable the ability to maximize the form by double clicking on the title bar.

Yes, setting the MaximizeBox to false did solve the problem. However, it seems to me that setting the ControlBox to false should have also prevented the double-click action, since allowing it means the ControlBox must be enabled after maximizing the window so that the window can be restored to original size.

Thanks
