Hi
If u want to limit it with 2 places than change field's datatype AS decimal(18,2) in
sql server.here 18 is the limit before decimal and 2 is the limit after decimal.

thanks

Try this code which should also prevent the user from typing more than 2 digits after the decimal point in the textbox:

private void textBox1_TextChanged(object sender, EventArgs e)
{
int len = textBox1.Text.Length;
if (len < 3) return;
int index = textBox1.Text.LastIndexOf(".");
if (index > -1 && (index < len - 3))
{
textBox1.Text = textBox1.Text.Substring(0, index + 3);
textBox1.Select(textBox1.Text.Length, 0);
}
}
