Re: Bind Datalist Control in another datalist control

31-Jul-06 23:06

In the page load you bind the first datalist and in the itemdatabound event of the parent datalist you bind the child datalist.

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})$">

For more details just visit this site:

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>

String constants must end with a double quote

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!

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

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

html controls access on server side??

31-Jul-06 22:49

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?
