Hi,

Here is the code

C#

Childform cf = new Childform ();
           cf .MdiParent = this;
           cf .ClientSize = new System.Drawing.Size(2000, 800);
           this.WindowState = System.Windows.Forms.FormWindowState.Maximized;
           cf .FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
           cf .Dock = DockStyle.Fill;
           cf .Show();

Don't forget to change anchor properties. I hope this helps.

It sounds like you have built an MDI application - in this case, all the children are contained within the border of the parent application, and cannot be any larger than the client area of the parent. You can make a child fill teh parent client area very easily: just set the WindowState property to FormWindowState.Maximized but you cannot make it fill the screen, or appear outside the bound of the parent.

To get the child outside, you have to just not set the MDIParent property before you show the form.
