❔ WinForms Refreshing parent Flowpanel issues

cartForm: runs a method called loadItems taking an array of items as a parameter.
This populates a flowpanel with a user control template called cartMenuItems.
The cartMenuItems template has a X button in the top right.
On click I want it to remove an item from the array, and then delete the flowpanel and re-run loadItems to update the panel.

The issue is making it so that onclick I delete the flowpanel and loadItems to update the panel.

public partial class cartForm : Form{
  public cartForm(){
    public void loadItems()
        {
            List<Item> itemList = new List<Item>();
            itemList.AddRange(Program.activeUser.getCart());
            for (int i =0; i<itemList.Count();i++)
            {
                {
                    cartMenuItem cartMenuItem = new cartMenuItem(itemList.ElementAt(i), getThisForm("cartForm"));
                    cartMenuItem.Text = ""+ i;
                    flowLayoutPanel1.Controls.Add(cartMenuItem);
                }
            }
        }
   }
}


public partial class cartMenuItem : UserControl
{
        public cartMenuItem(Item item)
        {
            InitializeComponent();
        }

        private void removeBtn_Click(object sender, EventArgs e)
        {
            Program.activeUser.removeFromCart(this.Text);
            cf.refreshPanel();
            
            //refresh visual list.
            cf = new cartForm(new string[] { }, Program.activeUser);
        }
}
