How to lazy load a route as a child route/component

阅读更多关于 How to lazy load a route as a child route/component

Let's take a look at my plunker: https://plnkr.co/edit/22RIoGsvzfw2y2ZTnazg?p=preview I want to lazy load a Module as a child-route. So the route /lazy should render the LazyModule into the <router-outlet> of my MainComponent . Then it will switch between that DummyComponent and the lazy loaded Module. Instead now that lazy loaded Module will be rendered into the AppComponent .. Any ideas? If you want to lazy load a module, do not import it as you've done here : src/app.ts : import { LazyModule } from './lazy/lazy.module'; ... @NgModule({ imports: [ BrowserModule, RouterModule.forRoot(routes),

Lazy-loaded NHibernate properties in Equals and GetHashCode

阅读更多关于 Lazy-loaded NHibernate properties in Equals and GetHashCode

How can the following problem be dealt with? We're using lazy loaded NHibernate properties and whenever we're calling Equals() or GetHashCode() any properties used, will be lazy-loaded, potentially causing a cascade of lazy-loading operations. Eager-loading could be used as an alternative, but I think only in specific cases and not as a general solution. A typical scenario would look like this: public class AbstractSaveableObject { [Id(0, Name = "Id", UnsavedValue = null)] [Generator(1, Class = "native")] public virtual long? Id { get; set; } } [Class(NameType = typeof(ClassA))] public class

I have recently changed all my beans from RequestScoped to ViewScoped . Suddenly, the lazy loading of dialogs does not work. I am using PrimeFaces JSF library. <html> <h:body> <f:view> <h:form> <p:commandButton id="addId" value="Add" title="Add" type="button" onclick="dlgMultiFileSelect.show();"/> ... </h:form> <p:dialog header="Dialog" widgetVar="dlgMultiFileSelect" modal="true" resizable="true" dynamic="true"> <ui:include src="/dialogs/media_browser.xhtml"/> </p:dialog> </f:view> </h:body> </html> Seems like dynamic="true" does not work since the backing bean in media_browser.xhtml gets

Need a sample for WPF TreeView search with Virtualization and Load On Demand

阅读更多关于 Need a sample for WPF TreeView search with Virtualization and Load On Demand

I need to implement search feature in WPF TreeView (basically I need to remember the last user selection). I have tried various approaches suggested but nothing works as virtualization is enabled in my TreeView and child nodes are loaded only when a parent node is expanded(lazy loading). Anyone knows of a sample having these three things(Virtualization, Load-on-demand and Search) implemented together? Have a look at this MSDN forum thread, Bob from MS explains the problem in implementing this feature. the cause is the VirtualizingStackPanel try to generate a item for display, but it has a

virtual keyword, Include extension method, lazy loading, eager loading - how does loading related objects actually work

阅读更多关于 virtual keyword, Include extension method, lazy loading, eager loading - how does loading related objects actually work

Loading related object in MVC can be pretty confusing. There are lots of terms you need to be aware of and learn if you really want to know what you're doing when writing your entity model classes and controllers. A couple of questions that I've had for a very long time are: How does the virtual keyword work and when should I use it? And how does the Include extension method work and when should I use it? Here's what I'm talking about; virtual keyword: using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace LazyLoading.Models { public class Brand { public

Images were Shuffled when scrolling a ListView with a ViewHolder

阅读更多关于 Images were Shuffled when scrolling a ListView with a ViewHolder

My problem is connected when the user scrolls the ListView. I looked around and saw numerous examples of 'listview lazy image', has also watched the video of the Google IO which speaks of 'good practice ' to make this work. But my problem continues when the user moves up and down the ListView. What happens is that when scrolling the list, the images that were loaded on each item are shuffled, and the avatar of each item going to the next item ends. I do not know if I'm being clear but I will show with the image. When you start, items that have no image left with the standard image. Image 1:
