Hi Narasiman  Try this... 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; } } } Thanks

hi Are you use window application or web application? if you use window application then you can also use regex string ^[0-9]*(\.)?[0-9]+$ it also validate decimal number. And for web application you can use java script for same. Please refer http://www.codeproject.com/Articles/11006/TextBox-which-accepts-only-numbers http://www.c-sharpcorner.com/uploadfile/tadas/numerictextbox12062005220207pm/numerictextbox.aspx hope this will help you.
