AJAX :: AjaxControlToolkit.ToolKitScriptManager.OnInit() Throws Thread Abort Exception For Every Aspx Page
Nov 3, 2010
AjaxControlToolkit.ToolKitScriptManager.OnInit() throws thread abort exception for every aspx page. I have an asp.net 2.0 Ajax application, where I have set the following properties of ToolScriptManager on my pages.
I have this configuration on all the aspx pages in my application. When I checked the .NET CLR exception Performance counter I figured out a large number of exceptions, mainly one exception per page load is occuring. On running windbg I was noticed that
AjaxControlToolkit.ToolKitScriptManager.OnInit() has the following code block which is getting executed. The OutputCombinedScriptFile() returns true. But since I am setting my controls on DesignTime still designmode is set to false for toolkitscriptmanager.
if (!DesignMode && (null != Context) && OutputCombinedScriptFile(Context))
{
// This was a combined script request that was satisfied; end all processing now
Page.Response.End();
}
I am not sure if this is a reported bug or even a bug with ajax, but this is causing havoc in my load test results as I have around 3 hundred thousand HTTP requests to be handled per day out of which 80% are aspx page requests resulting in a large number of threadafbortexceptions, thus affecting the performance.
what are the possible cases/causes for a thread abort exception? and how can we re-produce the same scenario if such exceptions can only be found on live production environment?
is it possible to access session variables when such exceptions occur or will session variables also get flushed and no longer be available? if we are able to manage/handle such exceptions, then will our application will continue to provide us a log for success/failure case of any particular task/process from where it was stopped?
i'm developing a ASP.NET web application which uses the AjaxControlkit 3.0.30512.20315. I have a ToolkitScriptManager instance on my master page which has some ScriptReferences in the CombineScripts collection. If i access my default page from 2 differenct clients after an iisreset, i get the following exception
[NullReferenceException: Object Reference not set to an instance of an object.] System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) +143 System.Collections.Generic.Dictionary`2.set_Item(TKey key, TValue value) +11 AjaxControlToolkit.ToolkitScriptManager.GetScriptCombineAttributes(Assembly assembly) +129 AjaxControlToolkit.ToolkitScriptManager.IsScriptCombinable(ScriptEntry scriptEntry) +148 AjaxControlToolkit.ToolkitScriptManager.OnResolveScriptReference(ScriptReferenceEventArgs e) +415 System.Web.UI.ScriptManager.RegisterScripts() +191 System.Web.UI.ScriptManager.OnPagePreRenderComplete(Object sender, EventArgs e) +113 System.Web.UI.Page.OnPreRenderComplete(EventArgs e) +8698462 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1029
Using .NET Reflector i found out that the GetScriptCombineAttributesmethod access a static dictionary, which is not protected against concurrent access. Either i have a race condition in my code or there is a bug in the AjaxToolkit.
I've read all the posts with this same issue and have not been able to resolve it in my case. Is the wrong version of the Toolkit being cached somewhere?
i m getting this error on my certain .aspx pages ,although i added tool kit in my project "Error4Type 'AjaxControlToolkit.ToolkitScriptManager' is not defined.C:UsersIramDocumentsVisual Studio 2008Projectsgfln1gfln1CreateNewConference.aspx.designer.vb3451gfln1
Usual javascript files can be cached on a client-side if web server sets the expiration. If user has once downloaded it, it will be cached by his browser.And what about AjaxControlToolkit ToolkitScriptManager? Are combined JS files cached on a client? How can expiration time be managed?
The following code listed on the bottom is a dropdown extender contained with a listview insert template. The code works fine however int VS 2008 Debug mode, its throwing the exception:Microsoft JScript runtime error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.If I click ignore or continue, the taret label is properly populated with the appropriate value. Has anybody encountered this and is
I have simple 3 tier web application and have mostly CRUDE functionalities. Recently I required to add new console application to the existing solution in which I call data layer methods for retrieving data from DB but I get an exception "The type initializer for threw an exception."When I debugged I found that the exception is thrown at datalayer on first line of class where I get connectionstring from
web.config, the code is public static readonly string CONNECT_STRING =
Now if I hardcode the connection string value like public static readonly string CONNECT_STRING = "Data Source=XYZ;uid=sa;password=XXX;initial catalog=ABC;"
it works fine.I don't understand what is the issue here as web application works fine with this datalayer.
I am using AjaxToolkit 4.0 which suggests to use ToolkitScriptManager in place of ScriptManager. But when I am using ToolkitScriptManager, it throws javascript exception when Page_ClientValidate() in called from javascript. However, this error is not coming when ScriptManager is used. Can anybody tell me how to make Page_ClientValidate() run when using ToolkitScriptManager?
Now i have added modal popup. Used ajax 15.1 toolkit. they said it doesnt require ajax script manager now.)
When i use it without ajaxscript manager it doesnt work. But when i use ajaxscript manager it works. But then i cant use scriptmanager (as two instance cant run).If i dont use script manager update panel wont work. Also i dont dont have any master page.
every now and then my server throws an exceeption. When it first starts to throw an exception the server wont work until I reinstall my web app (copy and Paste). I think this forces a restart of IIS and somethiong gets cleared bercause the app is working again for some hours, sometime less. Now I have created a scheduled task recopying all the web site files every 15 minutes. This restarts the server and the users are able to use the site. Problem is that now the server either start throwing exceptions, or the user is kicked because the server restarts. So you see, this is absolutly not a good solution.I have looked in the Event Viewer on the sever. Her is some examples of the exceptions:
[Code]....
An other exception:
[Code]....
As you can see, the common part of all the exceptions is the Exception message: Unable to cast object of type 'System.Int32' to type 'System.String'. Her is the code of one of the places throwing an exxception:
We have an old asp application that instantiates a .NET com visible class. In this class, we do some serialization to store our object in the session.
When I call the following line of code in my test class, it works fine.
var cereal = new XmlSerializer(couponApplicator.GetType());
However, when it gets called in the website and I am debugging, it throws the following error:
{"Cannot execute a program. The command being executed was "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe" /noconfig /fullpaths @"C:\WINDOWS\TEMP\rwot-yx9.cmdline"."} System.SystemException {System.Runtime.InteropServices.ExternalException}
I thought maybe it was permissions related so I tried giving 'EVERYONE' full control to the windows/microsoft.net folder as well as the windows/temp folder. For reference, I am running this on a Windows XP machine.
in my masterpage of my asp.net mvc 2 app. This method returns the version of the application.
i also have this code in my controller:
class GenericController : BaseController { [ChildActionOnly] public string Version() { try { string assemblyFile = Assembly.GetCallingAssembly().FullName; FileInfo fi = new FileInfo(assemblyFile); string version = fi.LastWriteTime.Year.ToString( ) + fi.LastWriteTime.Month.ToString() + fi.LastWriteTime.Day.ToString(); return version; } catch (Exception e) { return "1.0"; } } }
Now i get this error: Execution of the child request failed. Please examine the InnerException for more information.
and the innerexcpetion is: {"The controller for path '/Account/LogOn' was not found or does not implement IController."}
What i was thinking is that maybe the code can't execute because the user is not logged on yet, and tries to redirect to the logon method etc.
So the first thing i was thinking is to grant access in the web.config (like i do with the directory that has the css and images in it, it should also be accessable when you're not logged on:
I am hoping I am in the right place for this, I have a web application which has been running for about 4 years recently I updated my Ajax to the most recent version it continued to work OK then I changed from ScriptManager to ToolkitScriptManager now I get an error moving from my default page
I have a custom authorization attribute, that basically check if the current user's role is equals to the current area name, and if not, redirect them to the signup view in that requested area. (dummy role provider at this this stage, therefor check it against the user's name at the moment)
It runs fine (IIS) but when I debug it I can see a Security Exception are being thrown by the code
I have several text boxes in an asp:Panel. When the user hits Enter from any of those boxes, I want the form to submit as if they've clicked btnAddTag. (When the cursor is not in those boxes, I have a different default submit button.)
I am using Membership.DeleteUser("username",true) method to delete the user from DataBase. This works fine in my local machine. When i publish the same code, i am not able to delete the user..... it throws an javascript error saying..... "Login failed for user NT AUTHORITY/NETWORK SERVICE"
I have a date field in a typed dataset that created from database.
I get an NULL Value exception when I try to enter some null value. I am not able to set the Nullvalue property of the DateTime field in XSD to other value other than Throw Exception.
I have more than one user control and those user controls have extenders of the ajaxcontroltoolkit. The problem is that each one has a javascript that writes "function PageLoad"... and as I have more than one user control in the same aspx, more than one of those javascript functions is written in the output. Is there anyway to combine all of them in just one function? (bear in mind that the javascript code is written within the user control and the user control doesn't know anything about what other control are in the container aspx). If I have more than one function PageLoad they will not work then, right?
In Asp.net application. i cache a Linq to Xml result to a Cache object. when i cast the cache object back to generic list. i get the following exception.
[A]System.Collections.Generic.List`1[CarRentalAddress] cannot be cast to [B]System.Collections.Generic.List`1[CarRentalAddress]. Type A originates from 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' in the context 'LoadNeither' at location 'C:WINDOWSassemblyGAC_32mscorlib2.0.0.0__b77a5c561934e089mscorlib.dll'.

My code looks like this.
if (!Page.IsPostBack) { if (Cache["xml"] == null) { DataSet ds = new DataSet(); ds.ReadXml(HttpContext.Current.Server.MapPath("~/CarRentalAddress.xml")); var grid = (from d in ds.Tables[0].AsEnumerable() orderby d.Field<string>("City") where d.Field<string>("Enabled") == "1" select new CarRentalAddress { City = d.Field<string>("City"), HotelName = d.Field<string>("HotelName"), Address = d.Field<string>("Address"), EmailID1 = d.Field<string>("EmailID1"), EmailID2 = d.Field<string>("EmailID2") }).ToList(); Cache["xml"] = grid; totalrows = grid.Count().ToString(); grdAddress.DataSource = grid; grdAddress.DataBind(); } else { //Exception is thrown by this line var grid = (List<CarRentalAddress>)Cache["xml"]; totalrows = grid.Count().ToString(); grdAddress.DataSource = grid; grdAddress.DataBind(); } }
