Creating autocomplete for multiline textbox problems

Alright so the images weren't working so here is the code itself

private void textBox_KeyUp(object sender, KeyEventArgs e)
    {
        listBox1 = new ListBox();
        Controls.Add(listBox1);


        var x = textBox1.Left;
        var y = textBox1.Top + textBox1.Height;
        var width = textBox1.Width + 20;
        const int height = 40;

        listBox1.SetBounds(x, y, width, height);
        listBox1.KeyDown += listBox1_SelectedIndexChanged;

        List<string> localList = list.Where(z => z.StartsWidth(textBox1.Text)).toList();
        if (localList.Any() && !string.IsNullOrEmpty(textBox1.Text))
        {
            listBox1.DataSource = localList;
            listBox1.Show();
            listBox1.Focus();
        }

    }

    void listBox_SelectedIndexChanged(object sender, KeyEventArgs e)
    {
        if (e.KeyValue == (decimal)Keys.Enter)
        {
            textBox1.Text = ((ListBox)sender).SelectedItem.ToString();
            listBox1.Hide();
        }
    }

I have run into some errors and was wondering if anyone could help me with them. I am using the answer to this question. Any help is appreciated.

Current problems are:

listBox1.KeyDown += listBox1_SelectedIndexChanged;

List localList = list.Where(z => z.StartsWidth(textBox1.Text)).toList();

My errors are highlighted in bold.

You don't have any method listbox1_SelectedIndexChanged. So change 

listBox1_SelectedIndexChanged

to

listBox_SelectedIndexChanged

and you have bolded out List. It has to be your list of some object, which you haven't shown us. Change the name.

Note: When you copy do change the names as they are defined in your code.
