To be honest, I wouldn't. You can do it, by either handling the TextChanged and KeyPress events and validating that way, or by handling the Validate event but...
I'd use a NumericUpDown control instead, and set a maximum of 99999.9999 and a minimum of 0. It's easier, it's more flexible, and it allows the user to enter as many leading zeros as he feels like, without allowing him to enter alpha characters.

HI
You can use regular expression for textbox

<asp:regularexpressionvalidator id="rgx" controltovalidate="txtControl" runat="server" xmlns:asp="#unknown">
ErrorMessage="*" Display="Dynamic" ValidationExpression="^[0-9]\d{0,5}(\.\d{1,2})?%?$">

use this
it will help you.
