get multiple checkbox checked value in c#

In my web form I am generating multiple checkboxes dynamically. hence they are not in the control. I am trying to get the value using Request.Form[name] but it is not correct
<input type="checkbox" name="Suppresision" value="Suppresision" />Suppresision
Now I have a add button which dynamically (using Javascript) add more similar checkbox. So within my table element now I have
<input type="checkbox" name="Suppresision" value="Suppresision" />Suppresision
<input type="checkbox" name="Suppresision" value="Suppresision" />Suppresision
<input type="checkbox" name="Suppresision" value="Suppresision" />Suppresision
How do I try to get the values of all three ? I am doing the same for textbox but when I use Request.Form[textbox name] I get a comma separated values of all of them. But for the checkbox I do Request.Form["Suppresision"] I only get one value that too Suppresision instead of checked or not checked.How do I get all three value even if it not checked

If you absolutely need to get a list of all the checkbox controls you have dynamically added you could assemble them into a hidden input when you submit the form.
You need to include a hidden input for each set of checkboxes you add with a name like name="[checkbox name]_allValues"
<input type="checkbox" name="Suppresision" value="Suppresision1" />Suppresision 1
<input type="checkbox" name="Suppresision" value="Suppresision2" />Suppresision 2
<input type="checkbox" name="Suppresision" value="Suppresision3"/>Suppresision 3
<input type='hidden' value='' name="Suppresision_allVals">
Then add in this jQuery to loop the checkbox groups and you will have access to the full list of values for each checkbox on the server.
$(document.forms[0]).submit(function(event){
$('input[type=checkbox]').each(function( index ) { //loop all checkboxes
$itm = $( this );
$allVals = $('input[name=' + $itm.attr('name') + '_allVals]').first();
if ($allVals.length) { //see if we have a hidden input
$allVals.val($allVals.val()
+ ($allVals.val().length > 0 ? ',' : ' ') //add delemiter
+ ($itm.is(':checked') ? $itm.val() : '')); //add value
}
});
});
This way you will have access to the full list in Request.Form["Suppresision_allVals"] with blank values for unchecked boxes similar to what you have for empty textbox controls now.

You have same name attribute value for the three checkboxes. You should have different to make sure they can be read separately from the request form's collection on the server side. Also, in case of checkboxes, it should be checked attribute. Hopefully this will put you the right direction.
<input type="checkbox" name="Suppresision1" checked="checked" />
<input type="checkbox" name="Suppresision2" checked="" />
<input type="checkbox" name="Suppresision3" checked="" />

<input type="checkbox" class="chkItems" name="Suppresision1" checked="checked" />
<input type="checkbox" class="chkItems" name="Suppresision2" checked="" />
<input type="checkbox" class="chkItems" name="Suppresision3" checked="" />
var chkValue = [];
$('.chkItems:checked').each(function(i, e) {
chkValue.push({
chkItem : $(this).val()
});
});

List of checkboxes not getting selected

I have a checkbok as selectAll
Select All
<input class="all-select" type="checkbox" value="" name="">
i also have a list of friends with a checkbox each which is populated dynamically.
<ul>
<li><span><img src="img.src" ></span><strong>Name</strong>
<br />Email
<input name="" type="checkbox" value="" class="chk-box">
</li>.....</ul>
when i click the select all checkbox, then all the checkboxes of my list should get selected, the javascript code for which is given below :
$("#slide_top_pop").on("click", ".all-select", function (event) {
if ($(this).is(':checked')) {
$('input.chk-box').attr('checked', true);
} else {
$('input.chk-box').attr('checked', false);
}
});
Now the problem is this that when i first time select the Select All check box then the list get selected but when i unchecked it and check again then the list is not selected and when i tried to verify it on Mozilla what is the checked property(attribute) for the list then i get this :
<input class="chk-box" type="checkbox" value="" name="" checked="checked">
which says that the checkbox is selected but i cant see the selected tick in the list.
I dont understand what the problem is .
any solution is appreciated thanks.

Use .prop() instead of .attr() like:
$("#slide_top_pop").on("click", ".all-select", function (e) {
$('input.chk-box').prop('checked', this.checked);
});

Issue with processing form i ajax with radio buttons

I have this script which makes possible the insertion of some data using ajax and php.
Now , all works fine, except the radio buttons (the select options work fine as well) , and it takes the first value of the radio buttons..
Why is this happening?
Here is the code:
<div id="formfields" ><label>Tipologia Pdv: </label>
<input type="radio" name="tipologia_pdv" id="tipologia_pdv" value="Iper" style="width:40px;" /><span > Iper</span>
<input type="radio" name="tipologia_pdv" id="tipologia_pdv"
value="Super" style="width:40px;" /><span > Super</span><br /><br /></div>
<div id="formfields" ><label>Richiesta Ccnl: </label>
<input type="radio" name="richiesta_ccnl" id="richiesta_ccnl" value="Si" style="width:40px;"/><span> Si</span>
<input type="radio" name="richiesta_ccnl" id="richiesta_ccnl"
value="No" style="width:40px;"/><span> No</span><br /><br /></div>
The javascript:
// Fetch data from input fields.
var js_tipologia_pdv = $("#tipologia_pdv").val();
var js_richiesta_ccnl = $("#richiesta_ccnl").val();
//let's put all data together
var myData = 'postTipologia_pdv='+ js_tipologia_pdv + '&postRichiesta_ccnl='+ js_richiesta_ccnl + '&postDistretto_pdv=' + js_distretto_pdv + '&postCoopva_pdv=' + js_coopva_pdv + '&postNome_pdv=' + js_nome_pdv;
In php they go something like this:
$postTipologia_pdv = filter_var($_POST["postTipologia_pdv"], FILTER_SANITIZE_STRING);
$postRichiesta_ccnl = filter_var($_POST["postRichiesta_ccnl"], FILTER_SANITIZE_STRING);

Making my comments into an answer:
1) Your id attributes need to be unique.
2) Get the value of the selected radio button using something like: $('input:radio[name=tipologia_pdv]:checked').val();

How do I replace part of the value of attributes for a set of elements in jQuery?

I am trying to replace a series of 'for' attributes of labels based on their current contents.
The application is using AJAX to add an item to an invoice without refreshing the page. Upon receiving notification of a successful item add, my script should replace all the labels in the form whose 'for' attribute ends with '-new' with the same attribute minus the '-new' and adding ('-' + itemValue), where itemValue is the item Id of the invoice item that was added.
I know how to select all the labels I want to change at once:
jQuery('label[for$=new]')
I know how to get their 'for' attribute:
jQuery('label[for$=new]').attr('for')
I tried the JavaScript replace method:
jQuery('label[for$=new]').attr('for').replace(/-new/,itemValue)
But that appears to select each label's 'for' attribute, replace the text, and pass the replaced text back (to nothing), since I don't know how to identify the labels that have the 'for' attribute I want to replace.
Here's some sample HTML:
<form id="InvoiceItemsForm-1" action="<?=$_SERVER['PHP_SELF'];?>" method="post" name="InvoiceItemsForm-1" onsubmit="return false">
<div id="InvoiceItem-new-1" class="InvoiceItem">
<label for="InvoiceItemNumber-new">New Invoice Item Number: </label>
<input id="InvoiceItemNumber-new" class="InvoiceItemNumber" type="text" value="" name="InvoiceItemNumber-new">
<label for="InvoiceItemDescription-new">Item Description: </label>
<input id="InvoiceItemDescription-new" class="InvoiceItemDescription" type="text" value="" name="InvoiceItemDescription-new">
<label for="InvoiceItemAmount-new">Item Amount: </label>
<input id="InvoiceItemAmount-new" class="InvoiceItemAmount" type="text" value="" name="InvoiceItemAmount-new">
<input id="addInvoiceItem-1" width="25" type="image" height="25" src="/payapp/images/greenplus.th.png" alt="Add New Invoice Item" onclick="addInvoiceItemButtonPushed(this)" value="invoiceItem">
</div>
<button id="CloseInvoice-1" onclick="closeInvoice(this)" type="button">Close Invoice</button>
</form>
Once I get this to work, I'm going to replace all the ids for all the inputs. Same problem. I imagine the solution looks something like this:
jQuery('input[id$=new]').attr('id').replace(/-new/,itemValue)
I just cannot figure out the syntax for this at all.

No need to use .each() ... the .attr() method accepts a function as the second parameter that returns the new value to be used as replacement
jQuery('label[for$=new]').attr('for', function(index, currentValue){
return currentValue.replace(/-new/,'-' + itemValue);
});

If I may, why not just put the input tag inside the label tag? That way, you won't need a for attribute inside the label tag.
Next, a better way to accomplish what you're trying to do would be to use the invoice ID number as the ID for the surrounding div, and add a 'new` class for "new" invoice entries.
So your form would look something like this:
<form id="InvoiceItemsForm-1" action="<?=$_SERVER['PHP_SELF']" method="post" name="InvoiceItemsForm-1" onsubmit="return false">
<div class="InvoiceItem new">
<label>New Invoice Item Number: <input class="InvoiceItemNumber" type="text" value="" name="InvoiceItemNumber"></label>
<label>Item Description: <input class="InvoiceItemDescription" type="text" value="" name="InvoiceItemDescription-new"></label>
<label for="InvoiceItemAmount-new">Item Amount: <input class="InvoiceItemAmount" type="text" value="" name="InvoiceItemAmount-new"></label>
<input id="addInvoiceItem-1" width="25" type="image" height="25" src="/payapp/images/greenplus.th.png" alt="Add New Invoice Item" onclick="addInvoiceItemButtonPushed(this)" value="invoiceItem">
</div>
<button id="CloseInvoice-1" onclick="closeInvoice(this)" type="button">Close Invoice</button>
</form>
You'll still have all the targetability you need to get the new invoice item field data, but now, you only have two things to do to convert from a "new" invoice row to an "existing" invoice item row: add an id attribute to the div and remove the new class, both of which jQuery will let you do quite easily.

Not sure I get the question, but something like:
var oldFor = $('label[for$=new]').attr('for');
var newFor = oldfor.replace(/-new/,itemValue);
$('label[for$=new]').attr('for', newFor);
.attr( attributeName, value )
attributeName = The name of the attribute to set.
value = A value to set for the attribute.
When selecting multiple elements, you will need to iterate:
$('label[for$=new]').each(function(index) {
$(this).attr('for', $(this).attr('for').replace(/-new/, '-' + itemValue));
});

jQuery Store Values of checkboxes in div

How can I get this list of checkboxes to be added to a div prior to their selected state, so if they are selected, they should be added to the div, if not they are removed from the list if not selected.
<div id="selected-people"></div>
<input type="checkbox" value="45" id="Jamie" />
<input type="checkbox" value="46" id="Ethan" />
<input type="checkbox" value="47" id="James" />
<input type="checkbox" value="48" id="Jamie" />
<input type="checkbox" value="49" id="Darren" />
<input type="checkbox" value="50" id="Danny" />
<input type="checkbox" value="51" id="Charles" />
<input type="checkbox" value="52" id="Charlotte" />
<input type="checkbox" value="53" id="Natasha" />
Is it possible to extract the id name as the stored value, so the id value will be added to the div instead of the value - the value needs to have the number so that it gets added to a database for later use.
I looked on here, there is one with checkboxes and a textarea, I changed some parts around, doesn't even work.
function storeuser()
{
var users = [];
$('input[type=checkbox]:checked').each(function()
{
users.push($(this).val());
});
$('#selected-people').html(users)
}
$(function()
{
$('input[type=checkbox]').click(storeuser);
storeuser();
});

So you want to keep the DIV updated whenever a checkbox is clicked? That sound right?
http://jsfiddle.net/HBXvy/
var $checkboxes;
function storeuser() {
var users = $checkboxes.map(function() {
if(this.checked) return this.id;
}).get().join(',');
$('#selected-people').html(users);
}
$(function() {
$checkboxes = $('input:checkbox').change(storeuser);
});​

Supposing you only have these input controls on page I can write following code.
$.each($('input'), function(index, value) {
$('selected-people').append($(value).attr('id'));
});
Edited Due to More Description
$(document).ready(function() {
$.each($('input'), function(index, value) {
$(value).bind('click', function() {
$('selected-people').append($(value).attr('id'));
});
});
});
Note: I am binding each element's click event to a function. If that doesn't work or it isn't a good for what you are supposed to do then change it to on "change" event.

Change:
users.push($(this).val());
to:
users.push($(this).attr('id'));

This is for to bind the comma seperated values to input checkbox list
$(".chkboxes").val("1,2,3,4,5,6".split(','));
it will bind checkboxes according to given string value in comma seperated.
