Answer 1

if you want to make it simple, you could do this :

  string xyz = "Enter User Name Here.."; 
    private void textBox_Leave(object sender, EventArgs e)
    {
        {
            if (textBox.Text.Length.Equals(0))
            {
                textBox.Text = xyz;
            }
        }
    }

    private void textBox_Click(object sender, EventArgs e)
    {
        {
            if (textBox.Text.Equals(xyz))
            {
                textBox.Clear();
            }
        }
    }

and do put following lines to your form_load event :

    textBox.Text = xyz;
    textBox.Select(textBox.Text.Length, 0);
