DveExpress WinForm editors (TextEdit) have this functionality built-in already. Can be set through a property called NullText. — Bernoulli IT, Sep 13 '11 at 10:03

Do it via TextBox Events Enter and Leave and Attributes:

    private void textBox1_Leave(object sender, EventArgs e)
    {
        if(textBox1.Text.Trim().Length == 0)
        {
            textBox1.Text = "Search";
            textBox1.ForeColor = Color.LightGray;
        }
    }

    private void textBox1_Enter(object sender, EventArgs e)
    {
        textBox1.Text = string.Empty;
    }

Don't forget to change ForeColor back. – default locale Sep 13 '11 at 08:57
By the way, this one will clear the textbox every time I reenter on it. It's too hardcore, isn't it? – default locale Sep 13 '11 at 08:59
@MAKKAM: sharp! I edited the code to prevent user input to be resetted every time the users (re)enters the textbox... – Bernoulli IT Sep 13 '11 at 10:01
