protected  override  void  OnKeyPress(KeyPressEventArgs e)

    // Ignore all non-control and non-numeric key presses.

    if  (!char .IsControl(e.KeyChar) && !char .IsDigit(e.KeyChar))

        e.Handled = true ;

    // Call the implementation in the base TextBox class,

    // which raises the KeyPress event.

    base .OnKeyPress(e);

Hi Narasiman,

For Type only number in a textbox

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{

if (!System.Text.RegularExpressions.Regex.IsMatch(e.KeyChar.ToString(), "\\d+"))

e.Handled = true;
}
}
}

For Type only character in a textbox

using System;
using System.Collections.Generic;

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

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void textBox2_KeyPress(object sender, KeyPressEventArgs e)
{
if (Char.IsControl(e.KeyChar) != true && Char.IsNumber(e.KeyChar) == true)
{
e.Handled = true;
}

}
