Form stucked inside a panel

Question

Hi , i am trying to place a Form (which is added to a panel at run time) to the centre of the panel but found that it is always being positioned to the top left side of the Panel . Below is the code

// mainmaster is the Form name,login is another form .panel1 is placed inside the mainmaster .

  private void mainmaster_Load(object sender, EventArgs e)
        {
            login hm = new login();
            hm.TopLevel = false;
            hm.FormBorderStyle = FormBorderStyle.None;
            hm.StartPosition = FormStartPosition.CenterParent;
            hm.ControlBox = false;           
            panel1.Controls.Add(hm);
            hm.BringToFront();
            hm.Show();

        }

i have also tried to set the startposition property to centerparent in the designer toolbox window of login.cs but no avail . Please suggest what should i do Centre it .

Hi @Rahul Kumar , Welcome to Microsoft Q&A.

You need to set the location manually.

You also need to set the anchor attribute.

private void Form1_Load(object sender, EventArgs e)
{
    Form2 hm = new Form2();
    hm.TopLevel = false;
    hm.FormBorderStyle = FormBorderStyle.None;
    hm.StartPosition = FormStartPosition.Manual; // Set the start position to Manual
    hm.Location = new Point((panel1.Width - hm.Width) / 2, (panel1.Height - hm.Height) / 2); // Calculate the center position
    hm.Anchor = AnchorStyles.None; // Set the Anchor property to None
    panel1.Controls.Add(hm);
    hm.BringToFront();
    hm.Show();
}

Best Regards,
