javascript - ASP.NET - preserve style of HTML element after postback -

i had long break asp.net development.

i have div, toggled javascript function, on element's onclick function.

<div id="insdetail" style="display: none">

after postback, div's state reverted collapsed. easiest way preserve style of div between postbacks? (viewstate maybe?)

you can utilize hidden field (control) , update state (e.g 1 = visible 0 = hidden) when alter visibility of div. next restore state in load page event.

more o less

aspx file:

<input runat="server" type="hidden" class="statediv" id='statediv' />

js file or in page:

$(function(){ var visibility = $(".statediv").val(); if(visibility== 1) $("#insdetail").show() else $("#insdetail").hide(); $(your_botton).click(function(){ //toggle div if ($("#insdetail").is(":visible")) $(".statediv").val(1); else $(".statediv").val(0); }); });

in way can command state server-side

javascript asp.net viewstate
