compare validation in asp.net for negative numbers

Dear sir,

I am getting an issue with the compare validatr i.e for negative values i have a condition that is the second control text field shoudn't exceeding the value, it should be always less than or equal to first field.

it is working fine for the positive values but for negative values the condition is not satisfied.

the problem is like a scenario that is if first field is -22 and the second control field should less than -22 i.e -22, -23,-24,---- so on.

but i my cndition for negative values also my machine treated the values as positive numbers.

any soution,

thank you in a dvance

here is my code ,

If server side C#, you need to use Compare() method like below.

private static int CompareNumeric(int a, int b)
{
return a.CompareTo(b);
}

Below is the tesitng done.

//Positive numbers test
int n1 = 10;
int n2 = 20;
int comparison = CompareNumeric(n1, n2);
if (comparison < 0)
{
Console.WriteLine(string.Format("{0} is less than {1}", n1, n2));
}
else if (comparison == 0)
{
Console.WriteLine(string.Format("{0} is equal to {1}", n1, n2));
}
else
{
Console.WriteLine(string.Format("{0} is greater than {1}", n1, n2));
}
//Negative numbers test
n1 = -10;
n2 = -20;
comparison = CompareNumeric(n1, n2);
if (comparison < 0)
{
Console.WriteLine(string.Format("{0} is less than {1}", n1, n2));
}
else if (comparison == 0)
{
Console.WriteLine(string.Format("{0} is equal to {1}", n1, n2));
}
else
{
Console.WriteLine(string.Format("{0} is greater than {1}", n1, n2));
}
Console.ReadLine();

NB: I would suggest this checking to be done from client side using some JQuery methods i.e.

Math.abs()?
