In my current project we decided to build a Facebook application. This is really great platform with many interesting ideas inside, which usually means that you will spend a much time to make your application working as expected. Today I wanna talk about user profiles. Any Facebook application could add some action links, which will be displayed under the user’s picture, and some content for wide or narrow column. Of course, you can use FBML syntax, especially fb:if-... tags set to choose which content to show on specific profiles to concrete users.
Not so long ago I faced a problem of displaying count of some entities in singular or plural form (“No comments” or “less than a minute ago”, “1 comment” or “a minute ago”, “2 comments” or “2 minutes ago”). It’s very easy for English (there are three variants only), but I’m working on application that should be localized for several cultures. For example, in Russian we have at least 4 forms (“Нет комментариев”, “1 комментарий”, “2 комментария”, “5 комментариев”) and not so obvious rules for plural forms (“11 комментариев”, “111 комментариев”, but “21 комментарий”). I don’t speak any other language, but I think that several of them might be even more complicated than Russian. Here you can find my thoughts about such strings localization.
GridView is a great highly customizable ASP.NET control. Today I want to show, how to create derived control, which allows to add Digg-style pagination to your application.
ASP.NET has great limitation — only one server form on the page. Even if you are developing complex page, which looks like several forms with different submit buttons, in fact you have only one form. So we have a problem: How browser understanding which button should be triggered when user pressed ENTER? It uses first Button control (usually that’s wrong), and if you have LinkButton‘s, they would never be triggered. In ASP.NET 2.0 new property has been added to the Panel and HtmlForm controls — DefaultButton, which can be used to specify ID of the control, which implements IButtonControl interface (usually Button and LinkButton). This button control would be triggered when user pressed ENTER. But there is one big problem exist: LinkButton control would not be triggered in Firefox on ENTER. In this article I will show why this problem take place and how to solve it.
