Hi All

I was trying to give mouseover effect to ajaxcontrol toolkit accordion using javascript function. It worked great under normal aspx page but when i tried to use same code for my master page it gave me error ... can anyone please guide me where i am going wrong code is as below

<asp:AccordionPane  ID="AccordionPane1" runat="server">
                            <Header><span onmouseover="Openpane('0',event)">Home</span></Header>

its calling javascript as below

<pre lang="xml"><script type="text/javascript">
        function Openpane(paneIndex, eventElement) {
            var behavior = $get("Accordion1").AccordionBehavior;
            behavior.set_SelectedIndex(paneIndex);
        }
    </script>
</pre>

when i move my cursor over the accordion header it gives me AccordionBehavior' is null or not an object
error ... both the code are in master page NOT content page and javascript is in head section .....

any idea where i am going wrong ??

Thanks in advance ..

In what line? Can you run the script under debugger?

var behavior = $get("Accordion1").AccordionBehavior;

It simply mean $get("Accordion1") is null (not an object). If this is jQuery, the syntax is wrong, could be: jQuery.get, $.get or $.ajax. Please see:
http://api.jquery.com/jQuery.get/[^].

If this is something else, I'm not sure. You did not tag jQuery, so it can by nearly anything. For example "Accordion1" might not be in request, check up spelling. By they way, using such identifiers ("something1", "something2") is really bad; the artifact of Designer; it should be something semantic.

Solution 3

Try to use

$get("<%=Accordion1.ClientID%>")

instead of

$get("Accordion1")

Let me know if it doesn't work.

Usually when a control is not placed inside any of the server control, asp.net generates the clientID same as the ID provided at design time. But if the control is placed inside a server control then, the Client ID is auto generated by asp.net. Since you might have placed the accordion panel inside a ContentPlaceholder, the client ID would have been auto - generated.

Hence, its always good to access the Client ID as mentioned above.

and also, its not a stupid question, and u r welcome for any other clarification.
