How can I use this method to avoid listView flickering?

Question

public ListViewNF(IContainer container)
{
    container.Add(this);

    InitializeComponent();

    //Activate double buffering
    this.SetStyle(ControlStyles.OptimizedDoubleBuffer |
    ControlStyles.AllPaintingInWmPaint, true);

     //Enable the OnNotifyMessage event so we get a chance to filter out 
     // Windows messages before they get to the form's WndProc
     this.SetStyle(ControlStyles.EnableNotifyMessage, true);
}

protected override void OnNotifyMessage(Message m)
{
    //Filter out the WM_ERASEBKGND message
    if (m.Msg != 0x14)
    {
        base.OnNotifyMessage(m);
    }
}

In the Load event:

private void Form1_Load(object sender, EventArgs e)
{
    ListViewNF nf = new ListViewNF();
}

I'm getting error on the line inside the ListViewNF:

InitializeComponent();

Severity Code Description Project File Line Suppression State Error CS0120 An object reference is required for the non-static field, method, or property 'Form1.InitializeComponent()'

I tried to remove this line to avoid errors but it didn't fix the flickering. I also tried adding listView1, beginupdate and endupdate:

listView1.BeginUpdate();
foreach (ListViewItem li in listView1.Items)
{
    if (li.SubItems[2].Text == lastUrl)
    {
        li.SubItems[0].Text = "Downloaded";
        li.SubItems.Add("Color");
        li.SubItems[0].ForeColor = Color.Green;
        li.UseItemStyleForSubItems = false;
    }
}
listView1.EndUpdate();

I tried this before adding the ListViewNF method. So far nothing helped with the flickering. Any suggestions?
