XML

use a Range Validator for validating values in textbox
as percentage.set the MinimumValue as 0 and MaximumValue as 500.

For example you have texbox
<asp:Texbox ID="txtPercentage" runat=server></Text>

just set this ControlToValidate="txtPercentage"

<asp:RangeValidator ID="ranValidator" runat="server"             ErrorMessage="RangeValidator" ControlToValidate="txtPercentage"             MaximumValue="500" MinimumValue="0" Type="Double"></asp:RangeValidator>

Hi,

You can try this one.

JavaScript

function Validate() {
    var o = document.getElementById("valueCent");
    var val = o.value;
    if (val.length == 0) {
        alert("Please Enter Value");
        return;
    }
    var index = val.search(/[^0-9\.]/);
    if (index != -1) {
        o.selectionStart = o.selectionEnd = index;
        alert("Invalid Characters");
        return;
    }
    if (val.match(/\./g).length > 1)
    {
        alert("Invalid Number");
        return;
    }
    var floatVal = parseFloat(val);
    if (floatVal < 0 || floatVal > 100)
    {
        alert("Value must be between 0.00 and 100.00");
        return;
    }
    alert("Valid value of: " + floatVal.toFixed(2));
}

And to your HTML

HTML

<input id="valueCent" type="text" size="20">
<input type="button" value="Check"  önclick="Validate()">
