MDI Child Form TopMost problem ..

I have a MDI application, Form1 is parent form and Form2 is a child form.
On parent form(Form1) i put a textbox1 and button1
Then i call show method to show child form by click button1
this is my code.

private void button1_Click(object sender, EventArgs e)
{
Form2 frmChild = new Form2();
frmChild.MdiParent = this;
frmChild.TopMost = true;
frmChild.BringToFront();
}

The problem is... when when child form (frmChild) is displayed,
textbox1 and button1 is still on the top.
How to solve this, so that textbox1 and button1 is behind the form frmChild when the frmChild is displayed?
Thanks..

Did you put textBox1 and button1 on the parent? You'll need to put them in a panel that you dock on one of the sides of the parent.

Hi bullfreak,

Please try to use MDIClient which represent the container for multiple-document interface child forms. You can set the MDIClient as the parent container to the controls which is in the parent form.

Please refer to this thread for a simple implementation written by Rong-Chun Zhang.

Great..It's Work now. Thanks Bruce Zhou.

Hi!

The only way to solve this would be to set the .Visible property of all your controls on the Form1 form to false. From what I know, you can't have them visible and also the mdi child on top.

"dock on one of the sides" was the key phrase in my post.
