Can you show the markup? I'm interested in how you assigned the value to the checkbox...

Praveen Kumar Upadhyay 23-Dec-14 5:02am

I did not get, what is the link of the codes you have mentioned.

Mayur Ahir 23-Dec-14 5:22am

yes sure...see updates

Every click on your checkbox initiate a post-back to your page, that can clear all the state of the page...
How do you call the validation function?

You get value jquerry or code behind ?

If You Get Value By jquerry Code Like Below on Button Click

$("#demo").click(function () {
var selectedValues = [];
$("[id*=ChkBranch] input:checked").each(function () {
selectedValues.push($(this).val());
});
if (selectedValues.length>0) {
alert("Selected Value(s): " + selectedValues);
} else {
alert("No item has been selected.");
}
});

OR
CheckBoxlist Check Or Click Like Below

if jQuery >= 1.7

$('#ChkBranch').on('click', ':checkbox', function() {
if ($(this).is(':checked')) {
// handle checkbox check
alert($(this).val());
} else {
// checkbox is unchecked
alert('unchecked')
}
});

You can register a click event handler for all the checkboxes, inside the event handler this will point to the clicked checkbox

if jQuery >= 1.7

$('#ChkBranch').on('click', ':checkbox', function() {
if ($(this).is(':checked')) {
// handle checkbox check
alert($(this).val());
} else {
// checkbox is unchecked
alert('unchecked')
}
});
if jQuery < 1.7

$('#ChkBranch:checkbox').live('click', function() {
alert($(this).is(':checked'));
});
