回答1:
If you want to execute some javascript after partial postback, you can follow either of these methods:
Assuming you have a
<asp:ScriptManager />in your page you can include a function calledpageLoad()<script type="text/javascript" language="javascript"> function pageLoad() { // JS to execute during full and partial postbacks } </script>Or check out this link that explains about executing javascript during partial postbacks
http://csharperimage.jeremylikness.com/2009/06/inject-dynamic-javascript-into-aspnet.html
Another way is to use the Sys.Application.add_init handler as given below:
Sys.Application.add_init(appl_init);
function appl_init() { var pgRegMgr = Sys.WebForms.PageRequestManager.getInstance(); pgRegMgr.add_beginRequest(StartHandler); pgRegMgr.add_endRequest(EndHandler); } function StartHandler() { // your js } function EndHandler() { // your js }
Hope this helps!

To call this function after partial postback, what u need to do is re-register external js file. The following code does this.
private void RegisterClientStartupScript()
{
string path = Page.ResolveUrl("~/Script/slider.js");
ScriptManager sManager = ScriptManager.GetCurrent(this.Page);
if (sManager != null && sManager.IsInAsyncPostBack)
{
ScriptManager.RegisterClientScriptInclude(
this.updSpeech, typeof(string),"include-js",
path);
ScriptManager.RegisterStartupScript(this.updSpeech, this.updSpeech.GetType(), "SliderScript",
"FunctionName();", true);
}
else
{
this.Page.ClientScript.RegisterClientScriptInclude("SliderScript", path);
}
}
Call this function on every page load i.e outside (!isPostback). This code gets reference to external js file and in case it is a partial postback,it registers it with the scriptmanager. In case it is a normal postback it registers it with clientScript.
EDIT
Try giving the jquery function a name and then call ScriptManager.RegisterStartupScript().see the above code and replace FunctionName() with the name of ur jquery function. In the above code this.updSpeech is the updatepanel.
