Question

jQuery is not working after partial postback

Answer 1

A:

If you want to execute some javascript after partial postback, you can follow either of these methods:

Assuming you have a in your page you can include a function called pageLoad()

<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:

<script type="text/javascript" language="javascript">
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
}

</script>

Hope this helps!

Answer 2

A:

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.
