• changing ASP.NET tag formatting

  - by Steven

  When I drag a Label control to my document, I get the following code : <asp:Label ID="Label1" runat="server" text="Label"></asp:Label> I prefer my code to look like the following instead : <asp:Label ID="Label1" runat="server" Text="Label" /> How can I get .NET to do this by default? I looked in Tools - Options - Text Editor, where you'd expect to find it, but I couldn't find anything relevant there.

• Page expiration after postback in ASP.NET

  - by Achilles

  I've been doing web development for a while and have yet to read a good answer to this question: Given a page that executes transactions through a postback, how do you prevent the user from duplicating the transaction when they do something as simple as hit the back button? I've explored trying expire the cache but I must admit I'm lacking in my understanding of ASP.NET caching. What is the approach I should use to make the old request stale and invalid? Thanks!

• ASP.NET MVC with SQL Server backend returns old data when query is executed

  - by synergetic

  My ASP.NET MVC web app has a weird issue. In VS debugging mode it works as expected, but when I publish it to dedicated web server (windows 2003, IIS6) a sql query returns previous data even though underlying data was already updated through the same connection. It looks like as if a query returns cached data. What might be the problem?

• Multiuser XML document "database" for asp.net app

  - by Pierreten

  I was thinking about a way to allow multiple users to get CRUD access to an XML document in an asp.net app. The operations would obviously have to be made under the assumption of a multithreaded environment. For perf reasons, would it make sense to cache the document, and use a mutex on that cached version? When would changes be flushed to the physical XML document? Any and all recommendations are appreciated (also "use a database" isn't an option at this point unfortunately)

• Asp.net library to extract plain text from docx, pptx, xlsx (for search index)

  - by Myster

  Is there a pre-existing library to extract plain text form docx, pptx, and xlsx files? I require this to populate a lucene.net index. I've found this example which extracts text from docx and it seems to work ok. But before building my own solution based on this I was wondering if there's something already available for the other file formats?

• Automatically generating better views for ASP.NET MVC

  - by Casebash

  I am currently watching the 80 minute ASP.NET MVC introduction. Automatically generating views from a model is pretty neat, but it seems to me that that the automatically generated views could be much better. For a start, instead of inputing dates with text boxes, there could be a date control. Additionally, number inputs could be verified client side. There are probably other improvements that could be made as well. Is it possible to automatically generate better views?

• Logoff User when browser tab page is closed, ASP.NET MVC

  - by Gopinath

  In one of the ASP.NET MVC apps we would like to logoff the user automatically if he closes the browser tab in which the app is opened. We are using the following code when he authenticates.

But we want to ask users to authenticate again if they close the tab and try to access any of the website urls.

• ASP.Net MVC View within WebForms Application

  - by Neil

  I am adding functionality to an ASP.Net webforms application and we've decided that new development will be done MVC with a view to move all functionality over eventually. Obviously, MVC and WebForms play together rather nicely when it comes to accessing an MVC action via a URL. However, I'd like to display the MVC view within an existing tab (telerik) control on a WebForm page. This view will be using js/css file so that will need to be considered also.
