2.0 runtime javascript error - WebForm_PostBackOptions is undefine

Discussion in 'ASP .Net' started by =?Utf-8?B?UmljaA==?=, Jan 10, 2006.

  1. I am converting my enterprise solution from VS 2003 (.NET v1.1.4322) to VS
    2005 (.NET v2.0.50727). The entire solution uses serveral technologies -
    Windows Server 2003 (AD, SQL Server 2000, IIS, ASP.NET, ASP.NET Mobile)
    Windows Mobile 2003 (Pocket IE)

    I have completed a portion of the conversion (ASP.NET Mobile pages for PIE,
    and some of the ASP.NET-bases web services), and while
    testing I have a runtime error that did not exist in the 1.1 version.
    It is associated with a Windows Mobile ObjectList (mobile:ObjectList )
    When debugging on the desktop in IE 6.0 (I have *not* yet started conversion
    testing with PIE on the PDA), I click on a linkbutton in the object list and
    now receive a JavaScript error -
    WebForm_PostBackOptions is undefined.

    I am not using Javascript explicitly in my code, the error is caused by
    ASP.NET 2.0-generated Javascript.
    My .aspx code for LinkButtons in the ObjectList looks like -
    (<asp:LinkButton ID="lbnTask" CommandName="details" Runat="server"><%#
    ((ObjectListItem)Container)["name"] %></asp:LinkButton>)

    ASP.NET 2.0 generates javascript for the browser that looks like -
    <TD><a id="olstTask__ctl1_lbnTask"
    href="javascript:WebForm_DoPostBackWithOptions(new
    WebForm_PostBackOptions("olstTask:_ctl1:lbnTask", "", true, "", "", false,
    true))">medicate patient</a></TD>

    Previously, ASP.NET 1.1 generated javascript for the browser that looks very
    similar -
    <TD><a id="olstTask__ctl1_lbnTask"
    href="javascript:WebForm_DoPostBackWithOptions(new
    WebForm_PostBackOptions("olstTask:_ctl1:lbnTask", "", true, "", "", false,
    true))">medicate patient</a></TD>

    I know there is JavaScript embedded in System.Web.dll, for example -
    function WebForm_PostBackOptions(eventTarget, eventArgument, validation,
    validationGroup, actionUrl, trackFocus, clientSubmit)
    My C# code behind already has "using System.Web;", and I tried adding "<%@
    Import Namespace="System.Web" %>" to the 2.0 .aspx file, but it did not help
    with
    this issue.

    Is there a configuration step I am missing as part of the "port" to 2.0?

    I had a similar problem and it was a HttpModule that prevented ASP.NET
    from serving the "WebResource.axd" file (ASP.NET 2.0 uses this to
    deliver scripts, this is different to ASP.NET 1.1).

    Could this be your problem? Maybe try temporarily removing any modules
    and see if it goes away.

    Josh -
    Thanks for your reply.

    You said it might be that an HttpModule prevented ASP.NET from serving the
    "WebResource.axd" file.

    I am not at all sure what that means. Can you say a few more words about
    what I might check to see if it is blocked. A log file somewhere?

    Re: 2.0 runtime javascript error - WebForm_PostBackOptions is unde

    Most of the JavaScript functions used by ASP.NET are served by a new
    'page' called WebResource.axd. Can you see a link to this in your
    source, would look something like:

    <script src="WebResource.axd...

    I had a HttpModule that intercepted all requests to my service to
    rewrite urls (e.g. http://mydomain.com/showcategory.aspx?cat=taps to
    http://mydomain.com/taps). It turned out that this was stopping the axd
    from sending the script down and I got a heap of XXX is undefined
    errors.

    Josh,
    Thanks again for hanging with me!

    There is no reference to WebResource.axd anywhere in my "solution" directory
    (C:\Inetpub\wwwroot\poc_web\).
    However, under C:\WINNT\Microsoft.NET\Framework\v2.0.50727, in "web.config"
    (which I have not modified directly), there is a section that starts
    <httpHandlers>
    <add path="trace.axd" verb="*"
    type="System.Web.Handlers.TraceHandler" validate="True" />
    <add path="WebResource.axd" verb="GET"
    type="System.Web.Handlers.AssemblyResourceLoader" validate="True" />
    <add path="*.axd" verb="*" type="System.Web.HttpNotFoundHandler"
    validate="True" />

    etc....

    Does that look OK? Is there some other configuration change I need to make,
    or is there anything to look at while debugging?

    Re: 2.0 runtime javascript error - WebForm_PostBackOptions is unde

    Don't change that - that's supposed to be there. That's the bit that
    makes sure WebResource.axd works properly :)

    I suspect you'd know if you were using HttpModules, so this isn't your
    problem. To be sure you can check your web.config file and see if there
    are any httpModules configured. They'd be inside a <httpModules> node
    somewhere under <system.web>.

    However, I mean the web.config in your application, not the one in the
    the folder you mention above.

    Josh -
    I don't have any httpModules set up in the application-level web.config file.

    Any other ideas?

    Re: 2.0 runtime javascript error - WebForm_PostBackOptions is unde

    Hmmm, not sure...

    Let's make sure it is something to do with your WebResource.axd file.
    Have a look in your src, you should have a line that looks something
    like this (the random characters will be different)

    <script
    src="/WebResource.axd?d=3v2Q4FZSi09ZwjYwg-vpMg2&amp;t=632674154005468750"
    type="text/javascript"></script>

    Grab the src path and try and view the file in your browser, i.e. goto
    http://localhoast/MyApplication/WebResource.axd?d=3v2Q4FZSi09ZwjYwg-vpMg2&amp;t=632674154005468750


    (again your random chars will be different)

    You will probably need to save the file and view it notepad. If
    everything goes OK you should see a file full of lovely javascript...
    if not then something is wrong... let me know how you get on.

    You could also use ieHTTPHeaders to make sure the file is being
    requested and sent back with a normal 200 response code. I wrote an
    article about how to use ieHTTPHeaders here:
    http://www.thejoyofcode.com/Better_understand_Cookies_with_ieHTTPHeaders.aspx

    Hope that helps

    Re: 2.0 runtime javascript error - WebForm_PostBackOptions is unde

    Hi Rich,

    The source you've just sent doesn't contain any Javascript errors? I
    just c&p'd it into a HTML file and viewed it in my browser, worked a
    treat??

  11. Re: 2.0 runtime javascript error - WebForm_PostBackOptions is unde

    Josh,
    If you c&p to an HTML file it should display OK. (That gives you an idea of
    what my very ASP.NET mobile simple page looks like.) However, when I select
    the "medicate patient" list under the "Task:" column while running ASP.NET
    2.0 in the VS2005 debugger, I get a javascript error:
    WebForm_PostBackOptions is undefined.

    I previously did not get this error while running ASP.NET 1.1 in the VS2003
    debugger.

    My confusion (the reason for my original post) is around what might have
    gone wrong with the 1.1 -> 2.0 conversion process or with my VS 2005
    environment settings.

    Re: 2.0 runtime javascript error - WebForm_PostBackOptions is unde

    Strange...

    The medicate patient link works OK in full IE. There is no javascript
    error at all in the source you provided. Here's a snippet...

    <a id="olstTask__ctl5_lbnTask" href="javascript:{if
    (typeof(Page_ClientValidate) != 'function' || Page_ClientValidate())
    __doPostBack('olstTask:_ctl5:lbnTask','')} ">medicate patient</a>

    The javascript here says
    1. Is there a function called Page_ClientValidate available?
    2. If so, call it, if not don't (there isn't so it doesn't)
    3. Finally, it calls __doPostBack function (which is available - you'll
    see it at the top of you page) which causes the page to postback.

    And there the script ends.

    I beginning to wonder if this is a mobile IE problem and I run out of
    steam there. Sorry.

    Have a great weekend.

    Josh,
    I am such a putz!!!!

    The code I posted yesterday was the *1.1* generated client code, and not the
    *2.0* code. I am very sorry.

    The error is "WebForm_PostBackOptions is undefined", and the 1.1 file does
    not use WebForm_PostBackOptions. If you have a chance to take one last look,
    the 2.0 generated client code is below:

  14. Re: 2.0 runtime javascript error - WebForm_PostBackOptions is unde

    Apologies. My post identified the code as generated by the 2.0 server. In
    fact, I posted my 1.1 server-generated code. The real 2.0 server-generated

    Re: 2.0 runtime javascript error - WebForm_PostBackOptions is unde

    Hi Rich,

    You are a putz! Happens to the best of us :)

    There is clearly a problem with your 2.0 source. I just checked the
    contents of the JS file ASP.NET generates from WebResource.axd and sure
    enough it contains a WebForm_PostBackOptions and a
    WebForm_DoPostBackWithOptions function.

    The really strange thing is that ASP.NET for some reason I don't
    understand, is not inserting the link to the WebResource file in your
    source. It just isn't there. Is there anything that you're doing in
    your code that you think might affect this?

    Otherwise I'm not sure - if any MSFT guys are listening in on this, now
    might be a good time to step in! I have to go now but I will have a
    quick dig around for you tomorrow. I'm not that hopeful that I'll be
    able to get to the bottom of this for you remotely though.

    Hi,

    I knew it's too late. But today I experienced the smilar problem and set CausesValidation="False" of that button. It worked fine for me.
