PageError event of scriptmanager not firing

I have a content page that has a master page. I have an updatepanel and a scriptmanger in my content page. I defined a handler for OnPageError for the scriptmanager and defined a error template for the scriptmanager but when I set the e.errormessage in the OnPageError event, but if I set a break point in the event, the break point is never reached and the error message in the template still displays 'unknown error' Any ideas?

if I put a button on the page and in the click event of the button i manually throw and error.

thrownewException("error button clicked");

the event fires and works fine.

but if I put some invalid characters like '<img src' inside a textbox and then click the button (removing the throw) then the OnPageError isn't fired

PageError doesnt preserve stack trace

Hi,

I use the ScriptManager.PageError event in order to catch internal exceptions and rethrow them to be handled by the Application_Error event, just like in any non-ATLAS page.

The problem is that ATLAS clears the exception's stack trace and restarts it only from the PageError event handler itself.

I'm having hard time resolving the problems without having the original stack trace.

Any ideas?

Thanks,

Lior

hello.

are you sure about this? i seem to recall cehcking for a stack of an exception during the error handling...i maybe wrong since i don't have atlas installed here and can't check it right now...

Yes, I created an exception inside a function of a UserControl I'm using in my page, and this is the stack trace of the e.Error exception returned by theScriptManager_PageError event.

As you can see, there is no stack trace before the PageError event. When not using ATLAS, the Server.GetLastError() function returns the original exception with the original stack trace as an InnerException.

hello.

hum...here's an excerpt of a stack trace from an aspx on the error event of the scriptmanager:

at ASP.error.h(Object sender, EventArgs args) in d:\atlas\AtlasWebSite2\error.ascx:line 7
at System.Web.UI.WebControls.Button.OnClick(EventArgs e)
at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument)
at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument)
at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)
at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

as you can see, the error comes from an usercontrol which is inside an updatepanel,...

Hi,

My mistake. I did a "throw e.Error" in the PageError handler which, of curse, cleared the stack trace...

Thanks for your help,

Lior

I have the same problem in my page, but your post don't solve my problem. I did the same thing you did and rethrow the exception e.Error in the Script Manager PageError event hadler but the exception is again catched by the atlas framwork not by the application error handler and a popup window shows with the exception. Why is this happening?

hello.

well, if i recall correctly, scriptmanager catches all page erros and removes them so that the current request can be handled correctly. if it didn't do this, the client side would never receive the correct response (ie, the response wouldn't be in the correct format). if you need to log the error on the server, then handle the scriptmanager pageerror event and perform the loggin there. instead of showing the popup with the error, you can build your own error template which will be shown to the user in those cases...

No this is not what I need. The problem is this: when an exception is thrown i my atlas page inside an update panel a javascript win pops up with an message "Unhadled exception". I don't want that! I want that exception to be catch from a httpHandler that uses the Server.GetLastError() method and shows a message in the ErrorPage.aspx. This is it. How can I do that?

I tried to do this like it is said in previous posts

ScriptManager1.PageError += new Microsoft.Web.UI.PageErrorEventHandler(sm_PageError);

protected void sm_PageError(object sender, Microsoft.Web.UI.PageErrorEventArgs e) {
throw e.Error;
}

but it doesn't work.

I'm sorry the mistake was in my code. :)

pageLoad fires before script references are loaded

I have an aspx page with:

- a scriptmanager that has 2 script references. Both scripts have the "if (typeof(Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();" line at their end.

- a script section with a pageLoad function that calls a function defined in one of the 2 script references.

- an iframe (with src set to about:blank).

Result:

I get an "object undefined" error in the pageLoad function. with fiddler and in the debugger I can see that my script rerefences have not yet been loaded. As fas as I know, they should! It always worked until we added the iframe control. Removing the iframe control resolves the problem. To me this looks like an error in ajax where the pageLoad is executed on the load of the iframe contents instead of on the load of the main page.

Anyone any suggestion?

Could you share some code that reproduces this bug? I was unable to get the behavior you describe.

Are you using a function named pageLoad? Or Sys.Application.add_load(...)? Or Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(...)? Code would help a lot.

Thanks for looking into the problem. I will try to assemble a minimal solution that exposes the bug. BTW: it is a pageLoad function. In the debugger I saw that Ajax in the onload event looks if it exists and, if so, calls it. That's also how I found out that it gets called twice from this event handler. Give me some time to assemble the solution.

Thanks agian,

PageMethods is undefined

Hi there

I have a simple page that calls a server side page method via the scriptmanager / page methods detailed on this site. This has worked fine recently when until I updated our dev team to use the new asp.net ajax 1.0.

Once I'd updated my web.config as per the doco all works fine on my pc but on all others when I call the server side method I get the client script error " PageMethods Is 'Undefined' ". I am sure this is an environmental issue but I would appreciate any tips on how to figure out what is going on!

To update one of the boxes (eg our test server) I did the following steps.

Uninstall previous ASP.net Ajax (RC1)Install new versionUpdate web.config as per instructions in the doco

Here is my source code

<%@dotnet.itags.org. Page Language="C#" AutoEventWireup="true" CodeFile="AddNote.aspx.cs" Inherits="controls_AddNote" EnableViewState="true" %><%@dotnet.itags.org.

and here is the server code

 [WebMethod()]public static string SendNote(int TicketId,string DataSource,string Catalog,string Cube,string DataPointMdx,string NoteValue) {try {// Add a note to the server code and return a sample msgreturn"It Works"; }catch(Exception ex) {return ex.Message; } }

Any hints on troubleshooting would be greatly appreciated

Thanks in advance

Try settingEnablePageMethods="true"

<

asp:ScriptManagerID="ScriptManager1"runat="server"EnablePageMethods="true">

Yep thats it! Would probably be a good idea to add to the update doco

thanks

Was that missing in the documentation somewhere? We'll happily fix it... just point me to where it's missing.

There should probably be a section on Page Methods...in the docs that is accessible by the left hand side index..

Also, for whatever reason - the UpdatePanels UpdateMode is set by default to "Always" a special highlight in the docs should indicate this is the default and to change it to conditional for partial rendering / asynchronous updates. I was kinda surprised when investigating some of the post and issues on always full postbacks - that when I just dragged and dropped an updatepanel in designer - it defaulted to "Always"... kinda missing the purpose I think as if you are releasing this - then the default should err on side of the Ajax technology it is supposed to provide and this is a change I think from the RCs but not positive as I always declare everything anyways... but alot of folks just drag and drop and assume they are getting the settings for exploiting the Ajax enviroment...

I followed this docohttp://ajax.asp.net/documentation/Migration_Guide_RC_to_RTM.aspx

and unless I skipped over it I didn't find any reference to the EnablePageMethods

thanks again

I agree! Where can you find reference and documentation to PageMethods ? I use the block of code on this post as my reference right now ..

http://ajax.asp.net/docs/tutorials/ExposingWebServicesToAJAXTutorial.aspx

I agree this would be nice to see in the "differences" docs. I'll see if it can be added.

Just wanted to say thanks, all.

I was trying to get a method to run from a page (both in the .aspx file and in the code behind) and kept getting the js error of "PageMethods" not found. Adding that attribute to the ScriptManager cured the problem.

Partial refreshing problem with masterpage

Hi, everyone, I add a scriptmanager before updatepanel and updatepanel contatins only contentplaceholder in masterpage, but partial refreshing never takes action in ie6, each time I click, it postback whole page, I don't know why? To solve the problem I have add another updatepanel(contains a button and lablel) in masterpage, in that updatepanel partial refreshing works, but why if for contentplaceholder it doesn't work?

I am sure scriptmanager's partialrendering property is "true" . and I don't have a xhtmlConformance section in my web.config file.

I have searched some posts on this forum, but their problem seems does not fit for mine.

waiting for your answers

Bo.

Hello ,

Plz try the following url,it may not be the exact solution but it can direct u to the solution

http://www.devsource.com/article2/0,1895,1945460,00.asp

Hi，I found that in my project, Hyperlink in UpdatePanel can not support partial refreshing, while I setup another simple website, in its UpdatePanel, HyperLink can support partial refreshing, their environment is almost same. but Have different results, why?
