Update pannel not working

Dear all. I have an update panel and nested repeaters in it. I have image which when i click shows the other nested repeaters data and so on. The rows are shown and 开发者_JS百科hidden using the client script written on code behind.

The Page is working fine , but it refreshes the page every time i click to show data. If i put page in update panel, the page stops showing rows.

How to register the javascript with update panel.

This is how to register your javascript with the updatePanel: You place your javascript globally, out side UpdatePanel so your libraries loaded, and then using this code you initialized it on every update panel, if needed.

<script type="text/javascript"> 
var prm = Sys.WebForms.PageRequestManager.getInstance();    
prm.add_initializeRequest(InitializeRequest);
prm.add_endRequest(EndRequest);

function InitializeRequest(sender, args) {      
}

function EndRequest(sender, args) {

}
</script>
