Linkbutton inside update panel not working and causing exception

I page that contains an update panel. this page has a linkbutton that redirects to a new page and opens that page in a a new window(the page redirected to displays a picture). This linkbutton has been working all along with after adding this line of code in the pageload event.

ScriptManager.GetCurrent(Page).RegisterPostBackControl(LinkButton23)

suddenly, the linkbutton can nolonger redirect to the page when clicked and iam not aware of anything i did that may have crewed it up. I now get the following error message when i click it.

sys.webforms.webrequestmanagerParsererrorException: The message recieved from the server could not be parsed . Common causes for this error are when the response is modified by calls to response.write(), response.filters or server trace is enabled. Details: Error parsing near '<script language="ja'.

Actually i have noticed very strange behaviours by my IDE since i installed windows updates on tuesday, things like button click events not firing.

Any help.

Iam not sure if this extra information may help me get a reply. After some googling, most results are pointing to some thing to do with response.write in an update panel.

And in side the click event of my linkbutton, i have these javascript lines of code

ProtectedSub LinkButton23_Click1(ByVal senderAsObject,ByVal eAs System.EventArgs)

Dim myScriptAsString ="<script language=""javascript"">window.open('human Resources/viewer.aspx?id=" + employeenumber.SelectedValue +"') </" +"script>"

Response.Write(myScript)

EndSub

Iam not sure if this could be the cause of the problem but just in case.

<%@.PageLanguage="VB"AutoEventWireup="false" %>

I just changedAutoEventWireup from ="false" to="true" and every thing is back to normal, makes look stupid after wasting loosing over 8 hours. One more gotcha learnt though.

linkbuttons in accordionpane header

I am using an accordion that is created dynamically for a menu and have it working as I want - with one exception. When the user clicks on a dynamically created link button on the header, I want to redirect to another page WITHOUT triggering the default action of the accordionpane (expanding or collapsing). Is there any way to accomplish this? Currently, it triggers the default action of the accordionpane (expands or collapses it) then redirects.

Hi,

The expand/collapse action is fired by the <div> element that the header is wrapped in.

When you click in anywhere in the header, it's fired.

When you click on an element in the header, the element's click will be bubbled up to its parent( the header div ) , thus default action is fired too.

So, you can use javascript to prevent the LinkButton to bubble up the event to prevent this from happening.

The following code snippets help to illustrate my idea.

<script type="text/javascript">
function doSomething(e)
{
if (!e) var e = window.event;
e.cancelBubble = true;
if (e.stopPropagation) e.stopPropagation();
}
</script>

<ajaxToolkit:AccordionPane ID="AccordionPane1" runat="server" HeaderCssClass="myclass">
<Header>
<a href="http://links.10026.com/?link=">1. Accordion</a><asp:LinkButton ID="LinkButton2" runat="server">LinkButton</asp:LinkButton>
</Header>

protected void Page_Load(object sender, EventArgs e)
{
LinkButton2.Attributes.Add("onclick", "doSomething();");

}

Hope this helps.
