Question

I have a winform and opening other forms inside this using IsMdiContainer property. In contructor of parent I got :

    this.IsMdiContainer = true;
    this.WindowState = FormWindowState.Maximized;

then for child I got :

        child.MdiParent = this;
        child.WindowState = FormWindowState.Maximized;

for some reason if you maximize and restore down(not minimize) the child form shrinks each time. Now in child form I have a dock.fill panel and two groupboxes one docked to top and other dock to fill.

any ideas why this behaviour is happening?

Thanks

This shouldn’t happen. Check the code for your child form and see if you can find any additional size settings.
