Put EntityDataSource Attributes to Code-Behind

The EntityDataSource control is a very powerful one. It allows you to rapidly create database driven application. You don’t have to manually write code for extracting, modification and deleting records from the database. Moreover since this code is backed by Entity Framework, you are not tied up with a particular database schema and can easily change it or even choose other database application.

However when working with EntityDataSource sometimes I feel like I using plain old SqlDataSource and simply have too much unnecessary code in my .aspx files. More...

CSS Class Names Instead of ASP.NET Client IDs

In ASP.NET the client IDs of controls are often really unpredictable. When you need to add some JavaScript code that works with rendered controls you have to know their IDs. But usually an ID looks like something like this: “ctl00_contentBody_txtStreet”. There are several methods for overcoming that diffic ulty explained here. However they require writing additional code or even creating your own controls inherited from the original ones.

But there is one simply but yet dirty way of addressing HTML elements rendered by ASP.NET. More...

Multiple E-mail Accounts in Outlook 2007

Microsoft Office Outlook 2007 is an indeed great application. But when it comes to adding a new e-mail account one can simply feel frustrated, simply because every message received from that account will still be stored in the default account. I remember I was having a hard time after switching from Mozilla Thunderbird to Outlook when adding my e-mail accounts.

Hopefully, there is a workaround More...

NetBeans 6.5 as a Cute and Free IDE for PHP

Although I mostly blog about .NET and related technologies, tools, etc., this time I’m writing about PHP. I work a lot with PHP as well. And recently I got a small project to do and I was looking for a free but cute PHP IDE. I’m quite aware about Eclipse and PHP Development Tools for Eclipse, but I still was wondering if there is some other free tool for PHP. Eventually, I remembered NetBeans.

NetBeans is mostly known for Java developers as a good and free IDE. At the same time recently NetBeans started supporting other languages, like C/C++, Ruby and finally PHP. Moreover it not only supports plain PHP, but it offers quite good support of HTML and JavaScript. More...

Do You Suffer From Information Overload?

Do you ever feel surrounded by tons of information that you think you don’t have time to consume? I guess everyone remembers that feeling when you are glancing at your RSS reader and say to yourself: “Jeez, that’s really interesting, all that new development tools and useful refactoring patterns, but I don’t really have time for that, I need to finish my project, cause the deadline is coming”. In addition, there are also very interesting things that go around us, including Facebook updates from your friends, new photos from your Flickr pals and fresh tweets from your mates. In contrast to that *serious* news on software development, we always tend to read updates from our friends, moreover we become addicted to that kind of news, so we are constantly checking our e-mails, reply to instant messages and so on. In the mean time we still have to work and have normal rest away from the computer :)! More...

Send Your Feedback about Internet Explorer 8 and Other Beta Products

I must admit perhaps I was too rude when I was describing the glitches with IE8 Beta 2 usability. First of all, it was beta which purpose was to demonstrate new features and gather feedback, but no to present a completely finished product. Second, it were my own thoughts, but still IE remains the most popular browser on the Net and people must find it useable, since they use it.

Anyway, Internet Explorer 8 Release Candidate 1 is available now, which means that there won’t be any new functionality in the release, however if they find any bugs in the current RC, they will fix them and make RC2 available for public.

So, if you want to submit any bug report of feature request, I strongly advice you take part in the Microsoft Connect program that allows you to send feedback about their beta products, including Windows Azure, Windows 7, IE8 and many other products. Just navigate your browser to connect.microsoft.com, sign-in with your Live ID and choose an appropriate program. It’s advisable to search through the database before submitting your bug report or a suggestions, because it’s likely that other people have already spotted that bug and complained about it or came up with the same feature request.

Participating in such programs and sending feedbacks allows Microsoft to make better products that you will like ;-)!

Free Entity Framework Learning Guide

I came across a wonderful learning guide for the Entity Framework that explains many essential and complex things about the Entity Framework, including:

  • Modeling Entities
  • Lazy Loading
  • Inheritance
  • Working with objects
  • Performance
  • Working with Stored Procedures

Moreover this 500 pages long learning guide is absolutely free and can be downloaded here with all examples.

Thoughts on Internet Explorer 8 Usability

Well, Internet Explorer 8 is in the beta phase only, so it may be to early to judge it and make any conclusion. Anyway, I have some thoughts I want to share.

I’ve been a long time Firefox user, even though I cannot say anything bad about IE, unlike some other people who always tend to whine about it, I was just used to Firefox, anyway, I decided to try IE 8 Beta 1 and now I’m using Beta 2. It looked very promising to me. It passed the Acid2 Test, it has the Developers Tools and a built-in JavaScript debugger. So, Microsoft intends to release a more developer oriented browser that may surprise many web developers who have a bad opinion about Microsoft as a company that produced a very crappy browser and simply don’t care much about web standards and web at all. It’s not right, of course. More...

Understanding Attaching/Detaching Objects in LINQ to SQL and in the Entity Framework

LINQ to SQL and the Entity Framework are very powerful tools, however as in many other useful tools there are some things you should be aware of when working with them. One of those things is object attaching and detaching. Let’s have a concrete example.

As you already know, you can retrieve an object from the database, update or remove it and all the necessary changes will be submitted to the database.

But what if you don’t want to perform additional SELECT query? Instead, you want just to perform one necessary query, either to update an object or remove it. More...

The List of the LINQ to SQL and Entity Framework Providers

If you are using Microsoft SQL Server you don’t experience any problems, SQL Server are supported by both LINQ to SQL and the Entity Framework. Frankly speaking, it couldn’t be otherwise, since they all are made by Microsoft.

However, if you are using a non-Microsoft database engine, it’s certainly worth knowing if you can use LINQ to SQL or the Entity Framework with it. Moreover, it’s always better if there is native support. More...
