This works fine locally. A 404 throws a 404. On the shared hosting it throws up the standard server 404 page unless I specifically set 404 to point to /Error/NotFound. That's fine. Now it will show the custom 404 page except the response status code is 200. So if I try to throw Response.StatusCode = 404; in my NotFound action in ErrorController like this:
Csharp Code:
[code]....
the server throws a status code 500 Internal Server Error but my GeneralError page doesn't show, just a blank white page with no source.
I've tried many different combinations but I can't seem to find how to make it show my custom 404 page along with a 404 response.
How can I configure ASP.NET/IIS to show custom error pages (i.e. a nice friendly error page), but to still return a 404/500 status code so that google does not try to index the page? I have tried setting the Response.StatusCode to 404, but then the nice error page does not show anymore.
I have an ASCX control which is a special dropdownlist. I add that control dynamically to the page and fill it with data. This control has a postback that will change the contents of a second dynamically created standard dropdownlist.
When I change the selection on the first dropdown, the indexchanged fires and I get new data and attempt to place it in the second dropdownlist's items collection, by first clearing it then filling it with new data.
This works fine the first time a change the selection, but when I select a second time the following error is thrown:
The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.
I'm not adding or removing new controls in the fired event, only changing data. And again, it works the first time, but doesn't subsequent times.
If I disable stateview on the child control, then the control just doesn't get updated with data at all.
I have a page (generic handler) on which I want to return the status code 500 to the client to indicate that something is wrong. I do it like this:
Response.StatusCode = 500; Response.StatusDescription = "Internal Server Error";
And at the same time I render a friendly message telling the user that something went wrong. But instead of seing my message, I get the default IIS message saying something like this:
Server Error 500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed.
And if I go in to IIS and remove the error page for 500, I get this message:
The page cannot be displayed because an internal server error has occurred.
It works as intended in IIS6, but not in IIS7. What should I do to get it working in IIS7?
I am showing Custom Error in my page.if somehting happend wrong. but if the same error occured in my subview master page I am not able to show the Custom error page on Entire page its showing me that Error page under subview master page.I am attching the Screen shot.Can any body help me out how to show the Error page on entire page if something happend in any where submaster or other page.Here is the code that I am using in web config file to show custom Error page..
[CODE]...
Here I know the issue what's going on.This issue is occurring because i am using AJAX to partially load the contents of the tabs after the initial page load so the error is occurring AFTER my master page has been loaded.What I need to do is provide a javascript function to handle the error after the ajax call has returned and redirect to the error page.How to write this Javascript and where Do I need to write this?
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
Here's my Application_OnError event sink in global.asax.vb:
Sub Application_OnError(ByVal sender As Object, ByVal e As EventArgs) Dim innerMostException As Exception = getInnerMostException(Me.Context.Error) If TypeOf innerMostException Is AccessDeniedException Then Security.LogAccessDeniedOccurrence(DirectCast(innerMostException, AccessDeniedException)) Dim fourOhThree As Integer = DirectCast(HttpStatusCode.Forbidden, Integer) Throw New HttpException(fourOhThree, innerMostException.Message, innerMostException) End If End Sub
You'll see that if we've got an innermost Exception of type AccessDeniedException we throw a new HTTPExcpetion with a status code of 403 AKA 'forbidden'
So what we're expecting is a redirect to the AccessDenied.aspx page. What we get is a redirect to the ServerError.aspx page.
We've also tried this:
Sub Application_OnError(ByVal sender As Object, ByVal e As EventArgs) Dim innerMostException As Exception = getInnerMostException(Me.Context.Error) If TypeOf innerMostException Is AccessDeniedException Then Security.LogAccessDeniedOccurrence(DirectCast(innerMostException, AccessDeniedException)) Context.Response.StatusCode = DirectCast(HttpStatusCode.Forbidden, Integer) End If End Sub
I have web projects build in VS2003/1.1 framework and deployed in a webserver with IIS setting specified to 1.1 framework.lets say project X
I also have another web project which is build with VS2008/2.0. IIS setting - ASP version 2.0 is selected and all pages are assigned to run with 2.0* dlls. Lets say project Y
Now the problem seem to be when I hit project x, sometimes it throws errors like "error BC30456: 'Initialize Culture' is not a member of 'ASP.**"
During troubleshooting this issue, I browsed through 2.0 Temporary ASP.Net files "C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files" and found temp files generated for project X. (HUH?)
How/why 1.1 project gets compiled in 2.0 only when it errors out.( or we could put it this way that it errors out every time it gets compiled in 2.0 which it is not supposed to)
I'm confused as to why this is happening when project X has nothing to do with .net 2.0.
Adding this info:
IIS version 6.0
I forgot to mention that project X works 95 percent of the time without any errors under 1.1. This error throws randomly which we could not recreate. The time the project error out is at the same time it gets compiled with 2.0
I'm having a wicked time trying to redirect the different error scenarios to a custom error page. Basically, I have put some code in Application_Error in global.asax, and done the necessary web.config settings to use Custom Errors.
In global.asax on Application_Error, I stored the Server.GetLastError in Session. The reason I have to store it in Session is because (as far as I know) you lose the exception when using "ResponseRedirect". And the reason I have to use ResponseRedirect is because I am using an UpdatePanel with AJAX calls, and any exception during the AJAX call shows up as a JavaScript error, and doesn't get handled using the custom error page (see this post).
void Application_Error(object sender, EventArgs e){ ////must perform this check to avoid the "Session state is not available in this context" errors if (HttpContext.Current.Session != null) { Session["LastException"] = Server.GetLastError(); } else { // (I think this happens when there are compile-time errors) Server.Transfer("~/Oops.aspx"); }}void Session_Start(object sender, EventArgs e){ //must perform this check to avoid the "Session state is not available in this context" errors if (HttpContext.Current.Session != null) { //initialize the session (http://forums.asp.net/t/1405077.aspx) Session["LastException"] = ""; }}
I am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.
and when the value in the Database in null (""), it throws this error: ArgumentOutOfRangeException: 'pn' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I am using a Datapager in my project with a ListView control. The Datapager is set to use a querystring value Page, so that a typical URL looks like: [URL]. The problem is that the ListView throws an ugly error if the pageview is invalid (0, for example).
The error is: Specified argument was out of the range of valid values. Parameter name: startRowIndex
The error originates in the ListView SetPageProperties method. What is the best way to address this? Can I override the SetPageProperties method in some way, to check the startRowIndex parameter? Here's a very simple page that replicates the error: [URL]. A copy of a simple webapplication project demonstrating the error: [URL]
I am running through this tutorial on ASP.NET MVC: [URL] Everything seemed to be going fine. I created my DB, created my Model classes, created a controller class and then started creating some Action handlers. When I finally created the page that submits updates to the DB, I got the following error:
System.NotImplementedException: The method or operation is not implemented.
Line 49: public void Save()Line 50: {Line 51: db.SubmitChanges();Line 52: }
when I call the "SubmitChanges()" method of the DataContext class. I tried recreating my DBML file from my tables, but I still get the same error.
I added a service reference via the add service reference method. I can see all of its services in the intellisense but when I run the project and it executes the line where I instantiate the service : MyProjectName.ServiceReferenceName.IServiceReferenceClient client = new MyProjectName.ServiceReferenceName.ServiceReferenceClient;it throws this error:Could not find default endpoint element that references contract 'ServiceReferenceName.IServiceReferenceClient' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.
I have a conditional statement running on my aspx page which looks for a value from a static property (i.e. the object should not need to be declared).
[Code]....
This is the error that is thrown: "BC30451: 'CurrentSession' is not declared. It may be inaccessible due to its protection level."The class is public and to make matters more confusing, it works fine in certain environments but blows up on some.
I am using AS 400 OLEDB with .NET. It uses '?' instead of '@param to bind parameters with a commandNow there is a situation where the command is like
SELECT ... FROM (SELECT ... ROW_NUMBER() OVER(ORDER BY ColumnName) as RowNum FROM Employees e ) as DerivedTableName WHERE RowNum BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1 Now my command becomes SELECT ... FROM [code]...
I have a class library project which consumes multiple webservices. I have created a test project in VSTS and try to call one of those service
But I'm receiving System.ServiceModel.EndpointNotFoundException. In my Test Project I have added one app.config file and added endpoint as available in my Serviceclass library project app.config.
I've got a Dropdownlist with CategoriesI've also got a Listbox with Items filled using the selection from the DDL (autopostback=true).I have a SQLDataSource for each one.the DDL populates perfectly. the listbox SQL DataSource uses a stored procedure, that, on its own works perfectlyIt works well just as outlined above. However, when I add the following properties to the DDL, I get an error: appendDataBoundItems=true and '--Select--' (tried 'Select' also) as an item the error is:Input string was not in a correct formatI also set up the sqlDataSource selecting event handler, so that it would check for 'Select' first, but it bypasses that handler when debugging, and goes straight to the error msg

I need to send a Customized Error page for 503 Errors produced by my asp.net website. I have tried to simulate the condition by switching off the application pool (doesn't work) and by flooding my application with requests. Even though IIS sends me the default 503 error page, and even though I have tried setting a Custom URL in IIS and ASP.NET for this error code, it still returns me the default 503 error page.
