Lazy load for nonnavigation property in EF 4.1

馋奶兔 提交于 2019-12-02 00:20:14
问题 Is there a simple solution to make lazy load for nonnavigation property in the EF 4.1? For example, for byte array. 回答1: No EF doesn't provide lazy loading for scalar and complex properties. The trick is to use table splitting where data from single table are mapped into two entities related with one-to-one relation. One entity is the principal and it contains navigation property to the dependent and because of that you can use lazy loading. Here is the question with link how to do it in EDMX

Lazy loading tabs with user controls

夙愿已清 提交于 2019-12-01 23:00:00
I want to use lazy loading of tabs in AJAX tab container. I have implemented it. But the problem that I am facing is that when I click a button or fire any event in that user control, it is not fired; nothing happens. <asp:TabContainer runat="server" ID="TabContainerUp" ActiveTabIndex="0" AutoPostBack="true" OnActiveTabChanged="TabContainerUp_ActiveTabChanged"> <asp:TabPanel ID="tab1" runat="server"> <HeaderTemplate> <img src="images/uc1.png" alt="" /> </HeaderTemplate> <ContentTemplate> <asp:Panel ID="pnlUC1" runat="server"> </asp:Panel> </ContentTemplate> </asp:TabPanel> <asp:TabPanel ID=

Is it possible to implement live scrolling or lazy scrolling in a <div> which has <forEach> loop. I have the following codes in a <div> , I want to load the contents lazily. <div class="update" id="update"> <c:forEach var="p" items="#{statusBean.statusList}" varStatus="loop"> <h:form> <c:if test="${p.statusmsg!=null}"> <div class="status"> //content </div> </c:if> </h:form> </c:forEach> </div> Luiggi Mendoza Both JSTL and EL will be able only during view build time of the page (this is done by server). Ajax requests aren't part of view build time since they're in client browser, so JSTL and EL

conditionally load javascript (external and internal) and keep execution order

I'm looking for a way to conditionally load and keep the execution order of some javascript files (external and internal) without any library dependency. Basically, what I want to do is load them up only if the browser supports localStorage. Here's basically my shell: if (window.localStorage) { //load up JS only if it's needed var body = document.getElementsByTagName('body')[0], js1 = document.createElement('script'), js2 = document.createElement('script'), js3 = document.createElement('script'), js4 = document.createElement('script'), js5 = document.createElement('script'); js1.src = 'http:/

Lazy loading in MongoDB with NoRM

女生的网名这么多〃 提交于 2019-12-01 21:06:51
I have a model similar to this: (simplified) Question: public class Question { public string QuestionID { get; set; } public string Title { get; set; } public string Body { get; set; } public List<Answer> Answers { get; set; } } Answer: public class Answer { public string QuestionID { get; set; } public string Body { get; set; } } I intend to store the data in MongoDB, and would like to use NoRM with this. My question is: Is lazy loading supported? Or can I set it up to do lazy-loading on the document store..? So that requesting a Question, also retrieves the Answers..? (both will be "posts"
