An exception is thrown in the gridview because the database was not updated with the latest stored procedure. This is no uncommon situation, right?
The problem is that I have to debug to see the exception. If a just run the project everything looks fine (except that the grid never is loaded).
I want the application to crash hard when exceptions are thrown. How can I accomplish this?

Recently I have upgraded my app from .net 2.0 to 4.0. By running application under .net 4.0 I get one strange behaviour. Whenever application throw any error, instead of displaying it in browser with call stack, the error is shown in the browser's error window as javascript error and the whole web page remain as it is. is it feature of .net 4.0 or I need to do some settings to display error in web page.

I have a Visual Studio 2010 solution consisting of 2 projects:Core, a C# class library project which handles the functionality and data accessUI, an ASP.NET 4 website (.NET Framework 4) that references the Core, and calls functionality in the Core.
My exception handler is set in Global.asax (Application_Error.)When an exception occurs in the UI, everything works perfectly, I get filename, line number, etc.This is not the case for exceptions that occur in the Core.For this, I get a stacktrace like:
{FillUserCount at offset 2376 in file:line:column <filename unknown>:0:0}
P.S. The Core.dll and Core.pdb are present in the UI Bin folder.
In Visual Studio -> Tools -> Options -> Debugging -> "Enable just my code" is unchecked and "Enable source server support" is checked.Is there a way to get stackframe info (filename, class, method, line number) also for errors that occured in my referenced project ?
I have a asp.net website using C# that calls a C++ method using DLLImport. Everything was working fine and suddenly I keep getting this error:
External component has thrown an exception. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

n the script below I need to add a couple of tries before the exception is thrown. The Catch statement fails to detect some exceptions and my page displays an error if an unhandled error is generated. What usually happens is that the script tries to connect to the cube while the cube db is being renamed and that generates an error. I am trying to add a loop to force the reconnection after say 30 seconds and retry the querying. I want the script to generate the error only after the second/third failure .

I have a classical asp.net web service (asmx) and a web method in it. I need to throw a custom exception for some case in my web method, and I need to catch that specific custom exception where I call the web service method.
[Code]....
However, I cannot do that because when I add the web service reference on the client, I have service class, input and output classes, but I do not have custom exception class.
Also another problem is that, I have also problems with serializing Exception class (because of Exception.Data property implements IDictionary interface)
Is there a way to do this in my way, or am I in a completely wrong way, or is there something I miss about fundamentals of web services?
i'm using asp.net 2.0 form with ajax. i have an ihhtpmodule which can thrown an exception at Application_EndRequest step. my problem is that if this happen in an async postback (i mean a postback of an update panel) i can't manage the exception (with manage i mean set a custom error message server-side) becouse it's too late for the error handler of the ScriptManager.
(the alert will print a message as:
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near 'MyButt" />
|<html>
<head>)
at the moment my idea is to clear the response in the module and find a way to use the scriptmanager to send the correctly response of an error/exception. it's this possible? or samebody has another option of how to manage this case? note:i can't edit the aspx to manage this client client side with custom javascript
I have an ashx handler with the following code. The idea is to hide the path of the file and prompt a download

View 2 RepliesI have used the DataKeyNames property of the GridView to assign the column name whose visible property is set to false to get the cells value when the column is kept invisible. But, sometimes there is an error on this line of code - string cellValue = GridView.DataKeys[e.NewEditIndex].Value.ToString(); Following Error is generated -

It has to do with the RowCommand 'Cancel'. When clicking on my Edit button for a row, the GridView puts the row into edit mode without a problem (I have no code for the Edit command, I let the control do everything).
Once in Edit mode, if I click the Cancel button (again, I have no code handline this RowCommand, I let the control handle it (like i do with many other GridViews)) I get the following exception:
"System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I'm using Visual Web Developer 2010 Express with C# 2008 and .NET v4.0 to create a website which will have a database application. The database is SQL Server 2008.
I would have searched this forum for similar questions but I can't find a 'Search this forum' option! So I apologise if someone has already answered this.
I've successfully displayed rows from my database by dragging and dropping a GridView and an SQLDataSource control onto my page, and by using the Connection Wizard to set them up. But when I go live with my new pages, I will have to put my database in a different folder, and until I edit the web.config connection string to point at it I expect to get an exception.
I understand that when you try and open a database connection, this is the perfect place to use try...catch exception handling. But all the examples I can find put the try-catch code on the Button_Click event! Where should I put it? I can' t find anywhere where my controls actually attempt to open the database!
I know I could rip out what I've done and write all the code to connect to the database myself, but as I've finally got everything to work I would prefer to make the change as small as possible. So, what is the minimum change I have to make to add exception handling to my datasource/ gridview?
