Can Trap A Page Error
Jan 23, 2010
I use FileUpload to select a file and then I click an Upload Button to read the browsed filename. When I select a file that is larger than the max set in web config, my app crashes. The click Upload Button and the FileUpload control are in an ItemTemplate in a Gridview. If I select a file that is less than the max allowed, everything works fine.
How/where do trap this kind of error? I have tried breakpoints in my code behind, but it seems like the page crashes before any of the events I have tried to trap. I have tried a customvalidator to no avail.

I have some code that successfully traps an error 404 and diverts to an appropriate page. However, I have a problem with certain types of error. My code will trap the scenario where a user types, e.g.,
www.mysite.com/indecks.aspx where no such page exists. However, if the user types something along the lines
www.mysite.com/index.aspx/nonsensetext where index.aspx is a valid page, the page load event for index.aspx is triggered. However the page is rendered incorrectly because, I think, it is failing to find the images and CSS file associated with the page - perhaps because it is looking at the wrong path.
I expect that I can trap this by examining, for example, Request.URL.OriginalString and, if I detect garbage, I could re-direct to the same page "more cleanly" (i.e. without the junk on the end of the URL). However I'm a bit concerned that this is happening at all. Shouldn't this be treated as a 404 error?

i have a dummy javascript that can trap for enter key on the client side
Code:
[code]....
now look at the Elseif part, if the textbox is greater than and the user has pressed the return key(Enter) then it should execute the do whatever condition. i could do this on the client side , but my app requirement has changed so some of the code is on the server side.

I have implemented some javascript to handle the keypress of the "Enter" key to click a certain button. This has worked well on several pages but I have one that does not behave:View:
[Code]....
May return controller:
[Code]....
When I actually click a button, the value assigned to strButtonClicked is correct.Example: Click "Login" --> strButtonClicked = "Login"When I hit the "Enter" key, I get a different value.Example: Hit enter --> strButtonClicked = "I forgot my User Name and/or Password"Below is a View that works correctly:

I am hosting a solution with an outside company so getting them to troubleshoot or send me log files is not working.
Is there a way from code or Global.asax file that I can trap Memory usage from my web application when it reaches a certain amount? Then figure out what is using all the memory

I always used ASP FileUpload with great success, but recently tried to modify its appearance in order to blend in with the general appearance of the project. After extensive research I discovered that in this particular case it would not be possible and opted for an alternative.While not wanting to lose the functionality of the ASP FileUpload I hid the ASP FileUpload and rather just added a read-only textbox and button which I styled with ease. Subsequently I invoked the ASP FileUploads file browse window using Javascript. Consider the following:
Code:
<script type="text/javascript">
function ShowBrowseDialog()
{
[code]...
The above works fine for invoking the ASP FileUpload and selecting the file, but I need to work with the selected file(s) in the code-behind. Is there a way that I can trap a click event on the ASP FileUpload OPEN button, i.e. once the user selected the file(s)?

I have a data driven asp.net website with frames on the top, left, right and center screen. If a page generates an error on any of the frames, I want to redirect the whole site back to the Default.aspx. Currently, when a frame page errors in one of the frames, that frame gets the error pages. Site is URL.... Is this something that can be handled?

I have a serious problem with "Error on Page". The error message points to line number 939, char 13. In my code behind (C#) in line number 939 is only an obsolete method found which is no longer called. The aspx file has only 339 lines. What the heck is line number 939?The Webapplication allows a special user group to change some group memberships for members of another user group in Active Directory. The App handles 3internal DataViews derived from corresponding DataTables as DataSource for 3 GridViews and some other internal lists with objects (List<obj>).
It uses windows authentication to get current users credentials and his membership in the "Operators" group. This credentials will be passed-through to allow the process managing group memberships in active directory.After starting the App in browser it seems to work fine. But after an indeterminated time it doesn't longer respond. After each click on buttons (or link buttons) you only can see the message "Error on Page" in the browsers status bar below.I played with session timeout, storing the DataTables in session variables, without success.
Last week I found this article here: [URL]" and I addedEnableEventValidation="false" ViewStateEncryptionMode="Never"
to Page declaration. However, at some point the the server does not respond. Each time the worker process on webserver recycles it seems the application turn to wrong state. Might be important: All controls including GridViews are embedded in an AJAX UpdatePanel. How to get a better error message? Debugging is enabled and Custom Error handling On, Off or Remote Only brings the same result as described.

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"] = ""; }}

All the examples and websites i have looked at redirect a user to the error.aspx page when an error occurs. How do you just display a friendly error message on the page the user is viewing saying something like "Sorry unable to do whatever" I've tried using a try catch block on my class that executes a stored procedure and put another try catch on the controller, but this does not work and i still get the default error message (System.InvalidOperationException was unhandled by user code) My code is below:
[Code]....
So how can i just return ViewData["SqlError"] message in page.

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.
