Maximized Mdi Child is is cropped in mdi Parent

I think this is an easy solution. All i did is create an mdi parent that is maximized, next I created a mdi child and set it to open in centerparent, with same size as parent, and no controlbox and border style. Thus, I have a maximized parent and want the mdi child to open up maximized in there. Although it does open in the parent and is maximized, the top is cropped (it is too way up in the parent form). What am I doing wrong?

Hi, lostron,

Based on my understanding, when you open your maximized, none-border Child Form in your Mdi Parent Form, there is still some distance between the top of the Child Form and the top of yourMdi Parent Form, right?

I think this behavior is by design.

A trickyworkaround is to set the WindowState to Normal, but set the Dock of the Child Form to DockStyle.Fill.

For exmample

Code Block

Form2 form = new Form2();

form.MdiParent = this;

form.StartPosition = FormStartPosition.CenterParent;

form.Dock = DockStyle.Fill;

form.Show();
