Re: checking the string - ASP.NET Discussion Boards

Hi Apurva,

thanks a lot ! The help worked out..!

To give the detail of the problem i have two tables ,Master and the Detail table.

I have to bind the Detail table in the inner datalist control.

Could you please guide me how to create relation with in the datalist controls?

Actually what you need to do is put the child datalist in the itemtemplate of the parent datalist and then as i told first bind the parent datalist and then on itemdatabound event of the parent datalist you first find the child datalist and then bind it. onitemdatabounf event fires for each and every record of the datalist and there you can get the associated child records for the parent ID. you can use filter for that.

Hi,
By using regular expression you can able to do it.

Just go through the below coading:

<asp:regularexpressionvalidator id="regexpName" runat="server"
="" errormessage="This expression does not validate." controltovalidate="txtName" validationexpression="^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$">

the best way to do email validation is by using java script.
Just cut and paste the following java script. it will work fine.

<html>
<HEAD>
<SCRIPT LANGUAGE="JavaScript">
function emailCheck (emailStr) {
var checkTLD=1;
var
knownDomsPat=/^(com|net|org|edu|int|mil|gov|arpa|biz|aero|name|coop|in
fo|pro|museum)$/;
var emailPat=/^(.+)@(.+)$/;
var specialChars="\$\$><@,;:\\\\\\\"\\.\\[\\]";
var validChars="\[^\\s" + specialChars + "\]";
var quotedUser="(\"[^\"]*\")";
var ipDomainPat=/^\[(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})\]$/;
var atom=validChars + '+';
var word="(" + atom + "|" + quotedUser + ")";
var userPat=new RegExp("^" + word + "(\\." + word + ")*$");
var domainPat=new RegExp("^" + atom + "(\\." + atom +")*$");
var matchArray=emailStr.match(emailPat);
if (matchArray==null) {
alert("Email address seems incorrect (check @ and .'s)");
return false;
}
var user=matchArray[1];
var domain=matchArray[2];
for (i=0; i<user.length; i++) {
if (user.charCodeAt(i)>127) {
alert("Ths username contains invalid characters.");
return false;
}
}
for (i=0; i<domain.length; i++) {
if (domain.charCodeAt(i)>127) {
alert("Ths domain name contains invalid characters.");
return false;
}
}
if (user.match(userPat)==null) {
alert("The username doesn't seem to be valid.");
return false;
}
var IPArray=domain.match(ipDomainPat);
if (IPArray!=null) {
for (var i=1;i<=4;i++) {
if (IPArray[i]>255) {
alert("Destination IP address is invalid!");
return false;
}
}
return true;
}
var atomPat=new RegExp("^" + atom + "$");
var domArr=domain.split(".");
var len=domArr.length;
for (i=0;i<len;i++) {
if (domArr[i].search(atomPat)==-1) {
alert("The domain name does not seem to be valid.");
return false;
}
}
if (checkTLD && domArr[domArr.length-1].length!=2 &&
domArr[domArr.length-1].search(knownDomsPat)==-1) {
alert("The address must end in a well-known domain or two letter " +
"country.");
return false;
}
if (len<2) {
alert("This address is missing a hostname!");
return false;
}
return true;
}
</script>
</HEAD>
<BODY>
<form name=emailform onSubmit="return emailCheck(this.email.value)">
Your Email Address: <input type=text name="email"><br>
<input type=submit value="Submit">
</form>
</body>
</html>

That is probably the most over-bloated way of checking an email address ever...considering javascript supports regular expressions. String mashing to determine email validity is not a solution in todays programming world!

How to get answers to your questions[^]

Hi,

I found some problem in populating the Selected Items in the Shopping Cart.

In my ProductDetail Page, i have the Button for "Add Cart". When i clicked it, that particular item will be added to Cart and that "ShoppingCart" page needs to be displayed with Current Selection and Previously selected items ( if anything is already in cart).

I wish to do it without sending any data in URL. Probably i wish to use JavaScript to do this work..

Can anybody help me in this?

Thanks in advance.

Regars,

Jay

Hi all

Can any one tell what wrong here

Dim popupScript As String = "" & _
"window.open('PopUp.aspx', 'CustomPopUp', " & _
"'width=200, height=200, menubar=yes, resizable=no')"

Page.RegisterStartupScript("PopupScript", popupScript)

I wrote this code in .aspx page (stand alone page)

But it is giving this error

String constants must end with a double quote

THX

asdfasdfasdfasdfasdfasdfasdfasdfasdfasdf

I dont find any problem in that. I am not getting any compile time error after the compilation.

Best Regards,
Apurva Kaushal

It's probably the tag that ends your code in the middle of the string. Split the string in the middle of that tag.

Now it is not giving the error

Thank you Smile | :)

Its working fine here. Are you getting any javascript error?

Best Regards,
Apurva Kaushal

No
I wrote in on buttonclick

But the window is not opening

asdfasdfasdfasdfasdfasdfasdfasdfasdfasdf

Even there it is working fine. Check whether popup blocked for your browser. And also try it by putting that javascript code in a javascript function and add that as an attribute to the button.

Hi, How do I access an HTML control on my aspx's load event(code behind)? I've added a runat='server' to the control, but that buggers up my access to the control in javascript.

What do I do?

Regards,

Tintin

You just need to provide the runat and the id attbutes to access the html control in codebehind.

Best Regards,
Apurva Kaushal

if i add the runat attribute, document.getElementById('imgPic').src doesnt work anymore because the id tag changes to cl00_imgPic. And I cant get it to work with getElementByName.

Regards,

Tintin

where is the control placed in the webform? Are you using that inside of any other control.

Best Regards,
Apurva Kaushal

Regards,

Tintin

I dont fine any problem in accessing that in javascript.
whta i have used is:
var y = document.getElementById("imgPic").src;

and this is html part:
<table>
<tr>
<td>
<img id="imgPic" name="imgPic" src="Image/69.jpg" runat="server"></td>
</tr>
</table>

Best Regards,
Apurva Kaushal

if u set the html controls in the reapter,datalist etc.. the htmlcontrols or webcontrols will be add some words like "ctl00" before the html id
