Open A Form with a Form

RealistSpy

How do I open a form within a form (c# or any .net language) specifically in a panel.

Current Code

        private void FncButtonClick(object sender, EventArgs e)
        {
            var form = new System.Threading.Thread(FncForm);
            form.Start();
        }

        private static void FncForm()
        {
            CheckForIllegalCrossThreadCalls = false;
            Application.Run(new FNCForm());
        }

This will just currently load the form but not within the main form (panel).

The other problem I run into is flickering, both in the main form and the secondary form. E.g. Redraw is slow...

Solution:

        private void FncButtonClick(object sender, EventArgs e)
        {
            var temp = new FNCForm{ TopLevel = false };
            panel.Controls.Add(temp);
            temp.Show();           
        }
