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

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+"))
