I want to use such regular expression which only allow integers and
float value.
for example :--

12
12.34
23.456
0.5
0.0
0

I found but not able to find. Please Help me . Suggest me the regular
expression for that

What is wrong with you ?

1 - the easiest way to do what you want is to parse the values on the keypress event
2 - failing that, I have given you a regex that iwll work in all these cases. I've explained what you need to to to impliment it. Why would anyone bother, after the lengthy thread that exists below to try to explain a simple regex to you, get back on the treadmill and go through it all with you again ? May as well just bang our head against a well as try that.

Don't know why you marked your reply with the joke icon. It's all for real. Even the banging part.

Instead of having regular expression I did something like this:

I wrote a javascript function:

function onlyDigits(e)
{
var retKey = true;
var IsTwoDecimal = e.value.indexOf(".");
if (window.event.keyCode < 46 || window.event.keyCode > 57 || window.event.keyCode == 47)
{
window.event.keyCode = 0;
retKey = false;
}
else
{
//This code is used to restrict two decimal cost e.g.= 23.55 is valid
//but cost=45.55.66. is not valid.
if (IsTwoDecimal !=-1)
{
var s=e.value.split(".");
if (window.event.keyCode==46 || s[1].length>=2)
{
window.event.keyCode = 0;
retKey = false;
}
}
}
return (retKey);
}

<input id="txtCost" runat="server" type="text" onkeypress="return onlyDigits(this);" />

Hope this helps u???

I told her from the start this was a better way to do it, but she would not listen.

This Expression is well working for only integer and Float also.

It means she is stupid. I gave her roughly the same regex, and explained the need to put ^ and $ to make it validate the whole string, but instead she just asked the same question again.

And you answer her questions over and over again. You either have the patience of a saint, extremely bored or there is a clause in your contract which states you must attempt to help the stupid. I don't think there is a Sonia post on this forum without a reply from you. You're responses make reading her posts worth it!! And now Jamie has started as well.... She is impervious to it all - it's all wonderful stuff to read!

Gupta,

Are you doing some self-teaching? Or are you employed? If the latter, may I know which company that might be?

That wont help you showing textbox instead of dropdownlist doesn't mean that you are editing the dropdownlist

i think u r clicking the edit button and on clicking that the dropdownlist disappears and the textbox appears.if it's that
then simply click the textbox and go to Layout->position->Absolute , It should work i think

Hi Sonia,

Thanks for reply. I am using the style sheet as:

.textbox
{
position: absolute;
top: 60px;
left: 150px;
height: 20px;
width: 230px;
border: 0px;
font-family:Verdana;
text-align:left;
font-size: 9px;
font-style: normal;
color:#1E438D;
padding-left : 2px;
text-decoration: none;
z-index: 100px;
}
.combo
{
position: absolute;
height: 20px;
width: 250px;
top: 60px;
font-family:Verdana;
text-align:left;
font-size: 9px;
font-style: normal;
color:#1E438D;
padding-left : 2px;
text-decoration: none;
}

and here textbox is appears behind the combo which I dont want. I want the textbox to appear in front of combo so that I can type in something of select anything as I have kept the width of textbox less than combo.

Thanks again...
