C#

Hello there, I am trying to figure out how to refresh a user control, I have tried UserControl1.Refresh(); but it seems that it not doing anything. I need it so it refresh the listviews inside each usercontrol which is a total of 9.

What be the best possible method around this.

Thanks in advance.

Example of my coding

  private void refreshTheme()
        {
            /*
             uc_advancedWarfare.Invalidate();
             uc_blackOps.Invalidate();
             uc_blackOps2.Invalidate();
            uc_blackOps3.Invalidate();
            uc_ghosts.Invalidate();
            uc_modernWarfare2.Invalidate();
            uc_modernWarfare3.Invalidate();
            uc_mw.Invalidate();
            uc_waw.Invalidate();
            */

/*
             uc_advancedWarfare.Refresh();
             uc_blackOps.Refresh();
             uc_blackOps2.Refresh();
            uc_blackOps3.Refresh();
            uc_ghosts.Refresh();
            uc_modernWarfare2.Refresh();
            uc_modernWarfare3.Refresh();
            uc_mw.Refresh();
            uc_waw.Refresh();
            */



            //this.Refresh();
            var controls = new UserControl[]
            {
                this.uc_advancedWarfare,
                this.uc_blackOps,
                this.uc_blackOps2,
                this.uc_blackOps3,
                this.uc_ghosts,
                this.uc_modernWarfare2,
                this.uc_modernWarfare3,
                this.uc_mw,
                this.uc_waw
            };

            foreach (var uc in controls)
            {
                if (uc == null)
                    continue;

                uc.BackColor = this.BackColor;
            }
        }

What I have tried:

I have only tried the following

UserControl1.Refresh();
UserControl1.Invalidate();
