Hi Amol111,

The Selected tab will be maintained if the page is postbacked when the button "btnCustSave" is clicked if you are postbacking the page except then it wont maintain the selected tab.

Explain me the scenario when are the possibilities of the Customer Tab getting postbacked according to it there will be work around to maintain the selected tab.

 Hello Sir,

"btnCustSave"

"btnCustUpdate"

"btnCustClear"

"btnCustomerGridEdit"

these possibilities of the Customer Tab getting postbacked according to it there will be work around to maintain the selected tab.

Hi Amol111,

Replace all script which were given previously with below 

jQuery

<script type="text/javascript">
    $(function () {
        $('[id*=btnCustSave],[id*=btnCustUpdate],[id*=btnCustClear],[id*=btnCustomerGridEdit]').click(function () {
            localStorage.setItem('lastTab', $('[id*=Customer]').attr('id'));
        });
    });
    function pageLoad(sender, args) {
        var lastTab = localStorage.getItem('lastTab');
        if (lastTab) {
            $.each($('.tab-pane'), function () {
                if ($(this).attr('id') == lastTab) {
                    $(this)[0].className = "tab-pane active";
                    $('a[href=#' + $(this).attr('id') + ']').closest('li')[0].className = "active";
                    localStorage.removeItem('lastTab');
                }
                else {
                    $(this)[0].className = "tab-pane";
                    $('a[href=#' + $(this).attr('id') + ']').closest('li')[0].className = "";
                }
            });
        }
    }
</script>

hello Sir,

i used above Script It Works For( one button at only One time only)

And after refresh page another one button works but Remaining buttons not working properly.

Firstly I Click the Button "btnCustomerGridEdit" it works Perfectly but Another Buttons not Working Properly

But i Refresh the page And Click the Button "btnCustUpdate " its working properly And Another three buttons not working properly
