Dear expert,
please consider the following problem:
(1) You have assigned an inline event handler to a DOM element, like so <a id="link1" href="..." onclick=" ... ´">
(2) You also assign one or more further event handler(s) to the onclick event of link1 with the DOM2 or IE-specific assignment mechanism.

I am planning the implementation of an Inheritance Mapper pattern for an application component
http://martinfowler.com/eaaCatalog/inheritanceMappers.html
One feature it needs to have is for a domain object to reference a large list of aggreageted items (10,000 other domain objects)
So I need some kind of lazy loading collection to be p...
My main application form (WinForms) has a DataGridView, that uses DataBinding and Fluent NHibernate to display data from a SQLite database. This form is open for the entire time the application is running.
For performance reasons, I set the convention DefaultLazy.Always() for all DB access.
So far, the only way I've found to make this...
I've been reading Entity Framework and people were crying over why there was not implicit lazy loading or something. Basically I've been searching things about Lazy Loading and now I know what it is : It is a design pattern which allows us to load objects when they are really needed.
But what is the difference between Explicit Lazy Loa...
Hi,
I just found out that lazy loading in Entity Framework only works from the thread that created the ObjectContext. To illustrate the problem, I did a simple test, with a simple model containing just 2 entities : Person and Address. Here's the code :
private static void TestSingleThread()
{
using (var context = new Te...

Hi there, I wonder if anyone could help me with a problem I've been having.
I have a number of large images available, but due to space limitations, I can't create multiple copies of these at various sizes. I have used PHP GD functions to resize the images to the sizes I need and output them to the browser. This works, but obviously tak...

When evaluating dojo.require statements, dojo tracks which modules and resources have been required and doesn't download them many times, but takes them from cache.
But what if I require a module lazily, for example, when a button is clicked, - does dojo check its cache?

Hi all. This questions doesn't let me sleep as it's since one year I'm trying to find a solution but... still nothing happened in my mind. Probably you can help me, because I think this is a very common issue.

I'm using the jQuery lazy-loading plugin to defer loading of below-the-fold images on a large web page. This works great. Now, I would like to apply the same technique to a large Flash object which is also below-the-fold. I don't think the lazy-load plugin handles things that aren't images (at least it doesn't look that way so far.) I ma...
Dynamic Plugin Extensions
I'm looking for techniques to allow a jquery plugin or jquery-based javascript library to automatically and dynamically add extensions to itself based on the current environment it finds itself within. Basically, I want to be able to reuse certain useful functions from other plugins if other plugins are loaded ...
Suppose I have created a wrapper class like the following:
public class Foo : IFoo
{
private readonly IFoo innerFoo;
public Foo(IFoo innerFoo)
{
this.innerFoo = innerFoo;
}
public int? Bar { get; set; }
public int? Baz { get; set; }
}
The idea here is that the innerFoo might wrap data-access methods o...
I have a bunch of images that are in a hidden div. The div is shown when the user clicks on some links.
I'd like to jQuery lazyload to hide these images until the link is clicked and the hidden div is exposed. But, if I use lazyload according to the documentation, the images are always loaded as the hidden div is in the viewport, presu...
In Rob Conery's Storefront series, Rob makes extensive use of the LazyList<..> construct to pull data from IQueryables.
How does this differ from the System.Lazy<...> construct now available in .NET 4.0 (and perhaps earlier)?

I understand that this is highly specific to the concrete application, but I'm just wondering what's the general opinion, or at least some personal experiences on the issue.
I have an aversion towards the 'open session in view' pattern, so to avoid it, I'm thinking about simply fetching everything small eagerly, and using queries in the...
Hi folks!
In my iPhone app there is a scrollview (pagingEnabled=NO) which can contain up to 200 subviews (150 x 150) and the challenge is to do lazy loading and simulate endless scrolling (without bouncing) in horizontal directions.
Is there a solution or an alternative for this request?
Thanks a lot,
Daniel
