How to Enable/Disable asp LinkButton in jQuery

Problem
This is because there is no attribute disabled present inside the HTML rendered as you have a property Enabled="false". So, it renders something like below.

<a class="aspNetDisabled NextButton" id="Lnk_Orgnz"><div class="nbpad">Next</div></a>

As there is no disabled attribute, so it is unable to remove that.


Solution
Remove the Enabled="false" from the Mark-Up. So, LinkButton will be like below.

<asp:LinkButton ID="Lnk_Orgnz" ValidationGroup="CmpName" ClientIDMode="Static" OnClick="SubmitPart1"
        runat="server" CssClass="NextButton"><div class="nbpad">Next</div></asp:LinkButton>

Now, you have to disable it using jQuery, so do like below.

var _href;

$(document).ready(function () {    
    _href = $('[id$=Lnk_Orgnz]').attr('href');
    $('[id$=Lnk_Orgnz]').attr('disabled', 'disabled');
    $('[id$=Lnk_Orgnz]').removeAttr('href');
});

As a result of this, the HTML renders like below.

<a class="NextButton" id="Lnk_Orgnz" disabled="disabled"><div class="nbpad">Next</div></a>

Now, it has disabled attribute, so you can remove it if you want to Enable it.

To Enable the LinkButton, use the below code.

$('[id$=Lnk_Orgnz]').removeAttr('disabled');
$('[id$=Lnk_Orgnz]').attr('href', _href);

Note:- we are removing the disabled attribute and adding the href attribute again, which is added to LinkButton when it is first created.

Hope it solves you issue. I have tested it at my end; it's working fine.
