Prefer Overrides to Event Handlers in ASP.NET Page
Dflying | 29 March, 2006 06:43
First let’s take a look at two small pieces of code in an ASP.NET code file:
This one is the well known Page_Load() method. Actually it is an event handler which got executed when a Load Event defined in System.Web.UI.Page is fired.
// use event handler protected void Page_Load(object sender, EventArgs e) { // logic here }
This one, the OnLoad() method just overrides its base method.
protected override void OnLoad(EventArgs e) { // logic here base.OnLoad(e); }
Though the two methods above can do the same things to initialize your ASP.NET page, I prefer the override way.

New Features in ASP.NET 2.0 Page Model
Dflying | 13 March, 2006 01:40
The Attributes of the @Page directive
The @Page directive is the point of control for the developer with some new attributes that have been added to this directive:
- Async: If this is set to true, the page class that is generated derives from IHttpAsyncHandler. It adds some built in asynchronous capabilities to the page.
- CompileWeb: This attribute specifies the name of the referenced code-beside file to use for the page.
- EnablePersonalization: Indicates whether profile information should be used to build the page.
- MasterPageFile: This attribute specifies the path of the master to use for building the current page.
- PersonalizationProvider: this attribute specifies a valid provider defined in the application’s configuration file.
- Theme: specifies the name of the theme to be used.
If Boolean Async directive is used ASP.NET serves up the page in an asynchronous way. The page executes the custom code asynchronously while runtime progresses on the page life cycle. The request threads are synchronized and the output is generated in the browser by setting a single unwind point on the page between PreRender and PreRenderComplete events.
