I'm working on my first application using ASP.Net with web services and I'm having an authentication issue. At least I think that's the issue. When I run the application locally in debug mode it works fine. It even works when I run it out of debug mode (through IIS) in IE 7. But when I have a coworker run it (from my IIS) on their box, ...

I have some data that must be presented in tabular form with multiple sections. In particular, Each section of data is broken up (with it's own headers) by day.

Is it possible to authenticate users across sub-domains when the authentication takes place at a sub-domain instead of the parent domain? For example: User logs into site1.parent.com, and then we need to send them to reporting.parent.com. Can I authenticate them to the reporting site even though the log-in occured at a sub-domain? S...
We've got a ASP.net web app with a few pages that occasionally time out as the page loads (generally, these are all admin-type pages that do bug uploads / downloads with processing.) One of the solutions has been to bump both Session.Timeout and Server.ScriptTimeout up to very large numbers - which works fine. However, there's quite a ...

So i had a feature request to add fields to a second table row for a single data row on a GridView. At first, I looked at extending the functionality of the GridView but soon realized this would be a huge task and since I consider this request a shim for a larger future feature decided against it. Also want to move to MVC in the near fu...
I'm using the Context.Request.Cookies object to read/write cookies. I'm simply writing a single line of text that is delimited by tabs ('\t'). Immediately when I read back in the cookie through the Visual Studio 2008 debugger, the cookie object contains the string value, but all the tab characters are converted to spaces. When I publis...

What follows are examples I’m aware of where strong type checking is applied: a) Instead of performing string-based collection lookup, where entering the wrong name of a table or...
What's the best way to stream files using ASP.NET? There appear to be various methods for this, and I'm currently using the Response.TransmitFile() method inside an http handler, which sends the file to the browser directly. This is used for various things, including sending FLV's from outside the webroot to an embedded Flash video pla...

A few days ago, I wrote about issues with implementing a ListView in ASP.NET. Now, with all of the other code written, I'm having trouble saving changed items in a ListView. A few things of note: The Save button is not part of the ListView proper; it calls the GetListViewItems() method, which in turns call the Save() method. The Li...
