View 1 RepliesI am trying to passing Exception info tpa custom error page that I have created, and I'm looking for the best way to do so.I ended up creating a session object on my Global.asax page, and I pass the error data to the session object during the Application_Error event, but it throws it's own exception prior to working.
[Code]....
I have also updated my web.config with my error page that I would like to pass session object data to:

I tried both, loading the usercontrol when needed and I also tried adding it directly into the aspx.
Nothing worked. With the second one (what's meant to be the easiest option) I tried with delegates and events (but can't access de usercontrol event from page) and tried with properties (I can access properties but they're always empty)
I was wondering if someone could point me in the right direction:
How do I generate a custom error page with the error message and get it to mail me that error message?
Is there a good tutorial out there that someone could point me 2.
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 want put custom error page in my website so I wrote below code in web.config
<httpErrors errorMode="Custom">
<remove statusCode="404" subStatusCode="-1" />
<error statusCode="404" subStatusCode="-1" prefixLanguageFilePath="" path="error-404.aspx" responseMode="ExecuteURL" />
</httpErrors>
is it correct?
or I should put other 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'
Here's the relevant web.config entry:
<customErrors defaultRedirect="~/Application/ServerError.aspx" mode="On">
<error statusCode="403" redirect="~/Secure/AccessDenied.aspx" />
</customErrors>
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
Which unsuprisingly doesn't work either.
Being A C++ programmer this is fairly new to me - I am working on a formview and have been facing a problem- The issue is simple - I want to display a success page after I insert a row successfully and a custom error page if the insertion fails (due to datatype or format mismatch with table in database).
To achieve this I am doing as follows -
1. Defining a custom error page in ASP.NET configuration tool (webconfig)
>> This page never works if I enter an incorrect format in formview. It would rather display the ugly page with Server Error information (for example) -
The string was not recognized as a valid DateTime. There is a unknown word starting at index 0.
question - Why my default page is not getting displayed? Is it because I am testing from same development machine or is it because the error page doesnt work for "Server Error" pages?
2. In the "iteminserted" event I am redirecting it to Response.Redirect("~/newitemconfirm.aspx")
>> If I do this, irrespective of whether the row insertion was successful or not, this confirmation page always gets displayed! I want it to be displayed only on successful insertion.
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.
---------------------------------------------------------------------------------------------------
<sys.web>......<customErrors mode="On" defaultRedirect="~/Error.aspx"></customErrors>...</sys.web>
---------------------------------------------------------------------------------------------------
And even i tried in Global.asax page in Application_Error() method like below
Exception ex = Server.GetLastError();Response.Redirect("~/Error.aspx?errmsg="+ex.message);Server.ClearError();
And in my Error.aspx.cs page i have placed a label and i have written code like this
protected void Page_Load(object sender, EventArgs e) {
Label1.Text=Request["errmsg"];
}
But it is not getting redirected my error page and not displaying anything on it.
I have created a VS 2008 web setup project with a dialog so that I can modify the web.config file at install. The setup worked as expected. However, I can not seem to accept a URL for a property value via custom data. I know directories are escaped with "", is there any similar escaping or tricks for a URL.
View 1 RepliesI 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.

I have a custom control that I have created. I want to be able to pass in a Javascript snippet for a callback function. I am able to do this by passing a string back. The problem is that in the Javascript, I need to reference another server control that is not related to my custom control. So, I need to be able to pass in the ClientID of that control for use in the Javascript. Here is a snippet of what I am trying to do:
[Code]....
Now, I realize that '<%= chkStartDate.ClientID %>' will not be parsed. But, I need it to be parsed so the OnClientOnChangeEvent property of my custom control can take any Javascript for use as a callback. In this instance, I need to pass in the ClientID of the control for the Javascript function to find the control to work with; and this seems to be the one issue that I don't know how to handle.
I am using a custom error page in IIS 6:<customErrors redirectMode="ResponseRedirect" mode="On" defaultRedirect="Error2.aspx"/>I want to disable authentication for the custom error page because the error being raised is related to an authentication module and I don't want to get into an infinite loop and I want to display a clean error page to the user. I have been trying the following configuration to do that.

I'd like to capture the http referrer url following the rendering of a custom error page.I have this set in my web.config
<customErrors mode="On">
<error statusCode="500" redirect="/StaticError.aspx" />

In the OnLoad(EventArgs e) event -- I'm trying to do this, but it appears to be too late.this.txtReferrer.Text = Request.UrlReferrer.ToString();Is it possible to capture the referrer url?
I've a got an Asp.Net site that is using Forms authentication, I've also got custom errors configured in the web.config. One of these is a special error page for 403's (access denied). My question is how do I get Forms authentication to work smarter?
I would like Forms authentication to send users to login page only if they are not authenticated. If they are I want it to defer to the custom error pages that i've defined in the web.config. This seems like something very basic, how can this be achieved?

View 2 RepliesBasically I want to take the following:And make it match the styling of the rest of the application.I am creating a custom error page in my C# based project and I want it to be able to show the same information that is displayed in the ASP.NET default error page. From fiddling with reflector I can see that this is generated through HttpException.GetHtmlErrorMessage() but when I try to use this in my exception it returns null.

..................
later i am doing an error in a view page to see the error.
for example i am writing browser (localhost:5006/Home/46546465asjdas) and "Error/Error404" is working well.
but i am writing in view page
[Code].....
defaultRedirect="Error/Index" page not working.
I am trying to create a 404 error page and currently I have all of the following/tried all of the following to try and accomplish this. When the user types in :
http://name/something.aspx
It works just as its supposed to. But if the user types in:
http://name/NotAFile
with no .aspx then IIS7 takes matters into its own hands and I get the lovely error page that IIS7 comes with. The goal is that the site redirects with only a 404 status code (so not a 200, or a 302 redirect). I have tried in both the web config with:
<customErrors mode="On" defaultRedirect="~/error/Default.aspx redirectMode="ResponseRewrite">
<error statusCode="404" redirect="~/error/NotFound.aspx" />
</customErrors>
This works for the url with a .aspx file extension but not for no extension. Same with this approach in the global.asax
void Application_Error(object sender, EventArgs e)
{
var serverError = Server.GetLastError() as HttpException;
if (serverError != null)
{
if (serverError.GetHttpCode() == 404)
{
Server.ClearError();
Server.Transfer("~/error/NotFound.aspx");
}
Server.Transfer("~/error/Default.aspx");
}
}
The same results are present for this :( My final attempt was to apply this to the web config:
<system.webServer>
<httpErrors existingResponse="PassThrough" />
</system.webServer>
With this I just get a plain white screen with nothing on it...
In asp.net, I can define a custom error page like this:
<configuration>
<system.web>
<customErrors mode="On">
<error statusCode="404" redirect="/servererrors/404.aspx" />
</customErrors>
</system.web>
</configuration>
Now my question: If I replace, say 404.aspx with AnyHTTP.aspx, and want to get the number of the http error to generalize the page, how do I get that error numer?
