Check this

XML

<pre lang="xml"><asp:TextBox ID="txtCurrencey" runat="server" MaxLength="5"></asp:TextBox>
<asp:RegularExpressionValidator ID="rgfldvalidator" ControlToValidate="txtCurrencey"
runat="server" ErrorMessage="Please enter the numbers only" ValidationExpression="^[0-9]*\.?[0-9]+$">
</asp:RegularExpressionValidator>

Thanks to u and It'is not working according to the sample which i have shown above in my question. ur sample code is accepting continuous 4 digits before or after the dot.The only possible chances are mentioned in my query. No other Format it should accept.
