Hello

I have my aspx using master page

in master page i have written this below

<script 

language="javascript" 

type="text/javascript">
function load(){
Sys.WebForms.PageReque

stManager.getInstance

().add_endRequest

(EndRequestHandler);
}

function 

EndRequestHandler(){

$(".chzn-select").chosen(); 

$(".chzn-select-

deselect").chosen({ 

allow_single_deselect: 

true });

}
</script>

aspx code

<body style="padding:0;margin:0;background-position:top;background-repeat:repeat-x" 
background="images/bg.jpg"  onload="load();" onkeypress="return disableCtrlKeyCombination(event);"  >

Will this cause to load my page slow if no its okay

Hi,

I don't expect this to be a problem unless you are doing a bunch of Ajax requests when your page loads and/or your page is really complex.

If you have an issue it's best to look at what happens (for example use F12 and you have tabs to check http, JavaScript and rendering performance) rather than just reading the code and wondering if it is slow.

Hi asp.ambur,

According to your code and code, I suppose this is only add a value to the element property, this should not consume more time.

So my suggestion is check the execution time of this function or other function, this will better help you found out what cause your page load slow.

Here are two methods to check the function execute time, please check:
