In my 2nd ASP.NET MVC project I'm facing a very weird problem: when I call the SubmitChanges method of the DataContext class, nothing updates in the database. It's weird because everything works fine with my first project.
I'm using a remote database created in Sql Server Management Studio, I tried doing some queries there and in Visual Studio 2010 (where I have the connection to the database), they all work.
Where might the problem be hidden?
I've been reading about MVC in which the authors suggest that testability is one of the major strengths of MVC. They go to compare it with ASP.NET WebForms and how difficult it is to test the code behind in WebForms.
I do understand it's difficult but can someone explain how unit tests were written to test code behind logic in the old days?

I am using the System.Windows.Forms.WebBrowser object for displaying and printing a report. Unfortunately the Page Setup dialog is not obeying the language settings on the user's computer and all of the text is coming up in English.

I am using ASP.NET Callbacks (that implements the ICallbackEventHandler) and in the handler, I try to set a value of the text box:
txtName.text = "Test";
but this value is not set. Is this a limitation with callback? It appears I cannot do much in a callback handler other than sending back a string to the client side (ofcourse I can access the Session etc)

I just started using C# and I've got a couple of issues.
Is there any way to code the C# equivalent of the VB.NET Select statement like the following?

'Do something else
Case Else
'Do the default action
End Select
Any help would be greatly appreciated.

Hi SO community
I have been issued a problem with security. A bank will not allow use of DLL's in the project. What sort of structure would be needed to allow DataAccess and or the use of external services (like an email client mailchimp, icontct).

Thanks,

I just ran Google's Page Speed application against our site and one of the recommendations was to Leverage browser caching. Expanding this revealed the following:
The following cacheable resources have
a short freshness lifetime:
Specify an expiration at least one week in
the future for the following resources:
<a long list of images >
<some javascript files >
How do I go about lengthening the "freshness lifetime" of particular images?
It's an ASP.NET project running on IIS7.5

I'm working on an ASP.NET webapp using the MVP pattern, and as I'm organizing my files I'm wondering - are there conventions on folders within projects and how they relate to namespaces?
I have a bunch of controls and a bunch of pages, and I was going to throw them into Controls and Pages folders with subfolders, but I didn't know if it was bad form to do this if I wasn't also going to seperate them out into namespaces.
Thanks.
I wondering if I'm going to make a twitter app, but not sure which one of these libraries I should use. Any suggestions?

Hi,
what test data approach/framework is recommended for .net unit testing? I'm in VS2010, C#, doing business logic layer testing.
By approaches I mean like: creating database snapshots, programmatically creating each time, etc etc. Like what approach to use to ensure at the start of each test the database is in a known state.
Using ASP.NET and the DataGrid, how do I bind a HyperLinkColumn to more than one field?
Dim detail As New HyperLinkColumn
With detail
.Text = "View Details"
.HeaderText = ""
.NavigateUrl = "\TeamDetail.aspx?Account={0}&Broker={1}"
.DataNavigateUrlField = "AccountKey, BrokerNumberKey"
End With
I was hoping for an data-binding event on HyperLinkColumn but no such luck.
