lazy-loading

I have lots of images stored in isolated storage and want to display them in a listbox. However, I don't want all images to be loaded right away but lazily. So only when the user scrolls to see new items the images should be loaded. I also want to use data binding for providing the list item's data and image. In the tests I did all images always got loaded right away and at once, so I am unsure whether this lazy loading can be achieved with the default ListBox and data binding. Can it? You can use the standard ListBox to "lazy load" your items with databinding. The keyword here is "data

Could someone tell me how to make a good mechanism for async. download of images for use in a ListView/GridView?

How I expected to do it: I wanted to use 5 threads, so I figured I would have a shared Enumerator between the threads. Each thread would pop a value from the Enumerator, and run do stuff to it. Here's how I was thinking it

I am using Hibernate with spring. I have a model-class like this. @Entity @Table(name = "forumtopic") public final class Forumtopic extends AbstractUserTracking implements java.io.Serializable { /**SNIP **/ private Forumcategory forumcategory; @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "FkForumcategoryId", nullable = false) public Forumcategory getForumcategory() { return this.forumcategory; } public void setForumcategory(final Forumcategory forumcategory) { this.forumcategory = forumcategory; } } It works in general, but the Category is not loaded lazy, but eagerly after the

The Lazy plugin doesn't work fine for me. I've even added alerts to find where the problem is, but everything is ok for me. I try to use this effect of the plugin for my gallery. Here is my website page where I use jQuery.Lazy(). HTML: <div class="gallery-box col-md-9"> <div class="col-md-11 pull-right"> <ul> <li class="lazy"> <a href="images/gallery2/image1.jpg" title="Item 1 title ..." data-desc="Item1 a small cake baked in a cup-shaped foil or paper case" rel="lightbox[group1]"> <img style="width:200px; height:145px;" src="images/gallery2/thumb1.jpg" alt="Image description for search engins
