Making a listbox highlight items as you type?

[Andrew G]

If you make a hidden textbox (outside the screen with visible set to true), then use something like this, you can kinda make it work. I guess you'll need to add a timer to remove the text in the textbox after a second or so to make it function a bit better.

        public Form1()
        {
            InitializeComponent();
            listBox1.MouseUp += new MouseEventHandler(listBox1_MouseUp);
            textBox1.KeyPress += new KeyPressEventHandler(textBox1_KeyPress);
        }

        void textBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)Keys.Back)
            {
                textBox1.Text = "";
            }
        }

        void listBox1_MouseUp(object sender, MouseEventArgs e)
        {
            textBox1.Focus();   
        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {
            if (textBox1.Text != "")
            {
            listBox1.SelectedIndex = listBox1.FindString(textBox1.Text);
            }
        }

Edit: Updated code slightly
