I am trying to redirect to PageOne, with a URL string of status=true or false, which is based on this.
Label4.Text = this.Request.QueryString[CustomerStatus"];
And this label is what the customer "chooses." The only thing is that status is null right when I get into the onclick event listener for this redirect. How do I pass a variable in a response redirect without it becoming null, when this variable comes from the previous page, or response redirect from the previous page. Using static variables and such have proven difficult as they are not working either.

View 6 RepliesI have an asp.net application with separate classes for business logic and database interaction and then of course the UI. I am building a form to add a widget to a widget list table in the database. My UI collects the information and submits it to the business class. I'm going to write the business class to first double check that the widget has a name (I know I should do this in UI with validation, and I will, but this is just in case validation is forgotten) and if it does, go ahead and send the information to the database class. The database class will then attempt to write the info to the correct table using a try catch finally block. Any errors caught here are logged and then rethrown so I can inform the user. So, knowing that my database class may rethrow an error, my business class code will also be written in a try catch finally block.
So at this point I have a number of possible outcomes that I want to inform the user via the UI:
1) Everything was fine and the widget was added.
2) Something happened with the database write and the user should try again later.
3) The user forgot to name the widget.
My question is: should I write my UI in a try catch block and then throw a custom Exception with an Exception.Message in the business layer if anything goes wrong, or just have my business logic return a string that is the message? I'll want to know if the process was successful or not, because I'll want to format the actual message differently, so I'd have to use if...elseif to determine if the message was bad or not.
It seems like throwing a custom Exception in the business layer may be a good way to tell the UI something bad happened. If the UI doesn't catch anything then of course the operation was successful. Then again throwing an exception for missing data seems a bit hefty.
Here's my problem I have some code and I'm using it to send an e-mail with the last error details but all I want is the (Inner)Exception Message to be displayed in the email with the URL
Here's my code

I have
[ServiceContract]
public interface IBusiness

But......... the result
Error:The server encountered an error processing the request. The exception message is 'The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'UpdateLanguage'. The token '"' was expected
but found '''.'. See server logs for more details. The exception stack trace is:

I have a page here with a few list views on it that are all bound to Linq data sources and they seem to be working just fine.I want to add validation such that when a checkbox (IsVoid on the object) is checked, comments must be entered (VoidedComments on the object).
Here's the bound object's OnValidate method:
partial void OnValidate(ChangeAction action)
{
if (action == ChangeAction.Update) [code]....
Despite there being a dynamic validator on the page referencing the same ValidationGroup as the dynamic control, when the exception fires, it's caught in JavaScript and the debugger wants to break in. The message is never delivered to the UI as expected.
Using vb.net/asp.net 2005 and SQL Server 2005:I have a unique constraint setup to prevent users from entering duplicate email addresses in my online system.When a user tries to edit an existing email to one that already exists (add a duplicate) it shows the following<ERROR>Cannot insert duplicate key row in ojbect "dbo.someTableName" with unique index.....The statement has been terminated This prevents the user from adding duplicates which is good but I would like to provide a more user friendly exception message and I do not want to show the table and field names to the user.

not certain why this is happening, I assume that it's some server or config difference between the test and live sites. has anyone seen this before?

I've got a CreateUserWizard control and am performing server-side validation. Is there a way to force the CUW's error message to display from the code-behind? At the moment, if the user enters a duplicate name, the controls DuplicateUserNameErrorMessage property is displayed. However, if the user has turned javascript off, or sends a custom POST header, with invalid characters, I rely on my server-side validation to catch the error. How can I then display the same error message in the control's ErrorMessage label, instead of creating a custom label and faking it?
