Use code block for code segment.

Hello,

Personally I would use usercontrols rather than forms to do that.

UserControl1 userControl1 = new UserControl1();
UserControl2 userControl2 = new UserControl2();
this.panel1.Controls.Add(userControl1);
this.panel2.Controls.Add(userControl2);
userControl1.Dock = DockStyle.Fill;
userControl2.Dock = DockStyle.Fill;

You've set the Dock to Fill. Which means that one form will be on top of the other. That's why you can't see both.

I assume you're trying to create an MDI application. Set the start location correctly, and don't set the Dock to Fill.
