I'm using this code in every single btn, and actually works.

/*------------------------------------------------------------------*/
        // to show other form inside panel in main form
        users objuser = new users();
        pnlobjform.Controls.Clear();
        objuser.TopLevel = false;
        pnlobjform.Controls.Add(objuser);
        objuser.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
        objuser.Dock = DockStyle.Fill;
        objuser.Show();
        /*---------------------------------------------------------------*/
