How to make mdichild load at the center of mdiparent window

Question

HI all,

I have this code in which the window property of making child window load at the center of mdiparent.

        Form2 f = new Form2();

        f.MdiParent = this;

        //center screen is working.

        //f.StartPosition = FormStartPosition.CenterScreen;

        f.StartPosition = FormStartPosition.CenterParent;

but instead of making the child window pop at the center it loads at the left side. Can anyone help me on this. Please refer the screenshot below.

I have even tried doing the same in vb. Even there i get the same error. I think the property of FormStartPosition.CenterParent is dummy.

Answer 1

I experimented a bit with this, and first came to the same solution as Patrick. But I was bugged by the following statement in the documentation of the StartPosition property:

You can also position the form to display in the center of the screen or in the center of its parent form for forms such as multiple-document interface (MDI) child forms.

So, I decided that there must be a way. And there is, though I don't find it all intuitive: set the StartPosition to CenterScreen (not CenterParent):

MdiChildUI form = new MdiChildUI();
form.MdiParent = this;
form.StartPosition = FormStartPosition.CenterScreen;
form.Show();

Of course, you can also set it in the designer instead of in code.

Setting start position as center screen works perfect for me.
