Code-behind model. This works if you open your Web project via HTTP. Since the problem occurs in an SA file, you cannot use a reference directive to find the reference. My last acknowledgement goes to my best friend, my best man at my wedding, my sidekick since 1995, and now co-author Al Katawazi.  If you weren't my co-author, this book would check over here

Don’t be tempted to reuse an existing stored procedure or web service which returns large quantities of data when only a small subset of what it returns is actually needed – Figure 1. http://www.hanselman.com/blog/MostCommonASPNETSupportIssuesReportingFromDeepInsideMicrosoftDeveloperSupport.aspx

Performance Issues In Asp.net Application

This seems like a good transition for my first acknowledgment, which of course goes to my loving wife, Melinda.  She has been my constant supporter with her love and patience she You will want to take a quick look through the new ASP.NET classes.

  • In order for ASP.NET to know that the Button was clicked - and therefore raise its Click event - the Button name/value pair must be sent from the browser.
  • This could be misleading as .Net already caches that at the first call.
  • The screen shot below shows this raw data for the request and response to www.google.com.
  • Also identify how many SQL operations are involved in the rendering of each page and see if any of them can be coalesced – aim for the goal of at most
  • Enable web service output caching where possible.

This would show you that the page was posted back to when the Button was clicked or when the user hit the Enter key while focused in the TextBox control, and Fiddler works with a host of browsers, but works most naturally with Internet Explorer. (This article shows using Fiddler with Internet Explorer. Now that I have patted my own back I think I will mention some of the real contributors, without which this book would not have been possible. You'd be surprised how often folks put an app in production and they've never once profiled it.

The material is based on the highly praised and widely used ?TheBeerHouse? Asp.net Performance Tuning I would like to see what web page codes like this. In other words, the conversion wizard wasn't able to determine that the code-behind file was actually tied to a specific aspx page. https://support.microsoft.com/en-us/kb/910449 In Visual Studio .NET 2003 all the code-behind class files, and support code are precompiled into a single assembly with a fixed name.

We're in the process of converting our application to Asp.Net (MVC2) and I'm concerned that we will have the same problems or, considering the warning, possibly worse problems when we do.Brian We appreciate your feedback. Instead Nick and Al writes a custom validation using jQuery. Consider the following issue: you have an ASP.NET page with a form that contains a TextBox control, a Button control, and a Label control.

It is also possible that a Web form or user control was migrated twice—see the Multiple Web Projects Referencing the Same Files issue for ways to correct this issue.

If different code languages are used, it is recommended you move the Web projects into separate folders for conversion.

This new compilation model causes some changes in the structure of a Web application, but greatly enhances the options for deployment and how the Web application is served on the Web The detail of solving and tracing 500 internal server error with diagram is given here: Solve 500 internal server from IIS. The author explains carefully the concepts of the new Entity Framework, LINQ and AJAX very clearly in chapter 3. have a peek at these guys One thing I was a little puzzled about is why Nick and Al didn't use the ModelState for validation, it seems to me that that would have been easier, and you

While the Visual Studio debugger has greatly improved the debugging story, there are certain scenarios where a server-side debugger is of little or no help. Great purchase.Published on December 13, 2009 by C. If still not working, then yes, your next step should be enabling detailed error reporting so you can debug it. However, there is a workaround that is useful if you have hundreds of places in your code calling such auto-generated control variables, and you need to quickly get your code running.

The shared type will automatically be compiled and discoverable throughout your Web application. Quantum Based AI getting around Isaac Asimov's "Three Laws of Robotics" Two real articles before a noun – why? I leave it as an exercise for the reader…). Therefore if you have a Profile class in your application, and you try to use any of the new personalization features, you may encounter compiler warnings about ambiguous class references.

The solution is to create an abstract base class in the App_Code folder to reference at compile time, which will load the actual class from the page assembly at run time.
