using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace DemoWindowsApplication
{
    public partial class WaterMark : Form
    {
        public WaterMark()
        {
            InitializeComponent();
            textBox1.ForeColor = Color.LightGray;
            textBox1.Text = "Please Enter Name";
            this.textBox1.Leave += new System.EventHandler(this.textBox1_Leave);
            this.textBox1.Enter += new System.EventHandler(this.textBox1_Enter);

            textBox2.ForeColor = Color.LightGray;
            textBox2.Text = "Please Enter Address";
            this.textBox2.Leave += new System.EventHandler(this.textBox2_Leave);
            this.textBox2.Enter += new System.EventHandler(this.textBox2_Enter);
        }

        private void textBox1_Leave(object sender, EventArgs e)
        {
            if (textBox1.Text == "")
            {
                textBox1.Text = "Please Enter Name";
                textBox1.ForeColor = Color.Gray;
            }
        }

        private void textBox1_Enter(object sender, EventArgs e)
        {
            if (textBox1.Text == "Please Enter Name")
            {
                textBox1.Text = "";
                textBox1.ForeColor = Color.Black;
            }
        }

        private void textBox2_Enter(object sender, EventArgs e)
        {
            if (textBox2.Text == "Please Enter Address")
            {
                textBox2.Text = "";
                textBox2.ForeColor = Color.Black;
            }
        }

        private void textBox2_Leave(object sender, EventArgs e)
        {
            if (textBox2.Text == "")
            {
                textBox2.Text = "Please Enter Address";
                textBox2.ForeColor = Color.Gray;
            }
        }
    }
}

VB.Net
Imports System
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Data
Imports System.Drawing
Imports System.Linq
Imports System.Text
Imports System.Windows.Forms

Namespace DemoWindowsApplication
    Partial Public Class WaterMark
        Inherits Form
        Public Sub New()
            InitializeComponent()
            textBox1.ForeColor = Color.LightGray
            textBox1.Text = "Please Enter Name"
            Me.textBox1.Leave += New System.EventHandler(Me.textBox1_Leave)
            Me.textBox1.Enter += New System.EventHandler(Me.textBox1_Enter)

            textBox2.ForeColor = Color.LightGray
            textBox2.Text = "Please Enter Address"
            Me.textBox2.Leave += New System.EventHandler(Me.textBox2_Leave)
            Me.textBox2.Enter += New System.EventHandler(Me.textBox2_Enter)
        End Sub

        Private Sub textBox1_Leave(ByVal sender As Object, ByVal e As EventArgs)
            If textBox1.Text = "" Then
                textBox1.Text = "Please Enter Name"
                textBox1.ForeColor = Color.Gray
            End If
        End Sub

        Private Sub textBox1_Enter(ByVal sender As Object, ByVal e As EventArgs)
            If textBox1.Text = "Please Enter Name" Then
                textBox1.Text = ""
                textBox1.ForeColor = Color.Black
            End If
        End Sub

        Private Sub textBox2_Enter(ByVal sender As Object, ByVal e As EventArgs)
            If textBox2.Text = "Please Enter Address" Then
                textBox2.Text = ""
                textBox2.ForeColor = Color.Black
            End If
        End Sub

        Private Sub textBox2_Leave(ByVal sender As Object, ByVal e As EventArgs)
            If textBox2.Text = "" Then
                textBox2.Text = "Please Enter Address"
                textBox2.ForeColor = Color.Gray
            End If
        End Sub
    End Class
End Namespace

In above code I have fired event in when mouse cursor leave the textbox and enter in the textbox, we are assigning the value and making the color of textbox text change. Which provide watermark effect.
