Hi,

I have a panelbar with four panel items. In each panel item click I have to load a usercontrol for that corresponding panelitem. The javascript in usercontrol, which is loaded on PageLoad will work fine. But the javascript in the usercontrol, which is loaded in asyn postback will not work that is the javascript in that usercontrol is not loaded.

My problem is how to add the javascript in that usercontrol, which is added at asyn postback.

It is not working
---->

JavaScript

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "OnSelectData", "<script language='javascript' type='text/javascript'> function OnSelectData(obj,eventargs) { alert('OnSelect'); } </script>", true);

It is also not working

JavaScript

ScriptManager.RegisterStartupScript(this.Page, typeof(Page), "Hide", "<script language='javascript' type='text/javascript'> function OnSelectData(obj,eventargs) { alert('OnSelect'); } </script>", true);

Please give a solution for this problem.

Register you function in EndRequestHandler which as given below may work for you...

XML

<script type="text/javascript">
        try {
                        Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequestHandler);
        } catch (ex) { }
    </script>


function endRequestHandler() {
        /// <summary>Raised before processing of an asynchronous postback starts and the postback request is sent to the server.</summary>
               try {
              //add you function overe here
            }
        }
        catch (exeption) { }

    };
