Exception typeCondition


A top-level window cannot have an owner.

To make a form owned by another form, assign its Owner property a reference to the form that will be the owner.

When a form is owned by another form, it is minimized and closed with the owner form. For example, if Form2 is owned by form Form1, if Form1 is closed or minimized, Form2 is also closed or minimized. Owned forms are also never displayed behind their owner form. You can use owned forms for windows such as find and replace windows, which should not disappear when the owner form is selected. To determine the forms that are owned by a parent form, use the OwnedForms property.
