page-lifecycle

问题 commonly on say PHP or other web frameworks getting the total response time is easy, just start the timer at the top of the file and stop it at the end. In ASP.Net there is the whole Page Lifecycle bit though so I'm not sure how to do this. I would like for this response time recording to take place in a master page and the response time show up in the footer of pages. What would be the best way of doing this? Is there something built in to ASP.Net for it? Is it even possible to include the

问题 The expected order of HttpApplication methods is: Application_Start Init Application_BeginRequest Application_AuthenticateRequest (page life cycle) Application_EndRequest I'm passing through a situation, which throws absolutely no exception, in which, after the Init, it goes directly to ApplicationEndRequest. It doesn't call Application_BeginRequest neither initiates the page life cyle. What do I do? 回答1: Application_EndRequest is called but not Application_BeginRequest when theres an

问题 Could I get some confirmations from the community that I'm not going mad, and that the life cycle of a page during post back is in deed in a different order to when the page is initally requested. If this is the case pointers towards references/articles outlining the order would be greatly appreciated. (A postback equivalent of the page life cycle image would be great) 回答1: The behaviour is slightly different but the order is the same. In this respect "Postback" is essentially a state flag on

问题 Is there something like a lifecycle for jQuery Mobile pages? Like events that get fired on init, show, hide/back, or whatever events?!

问题 I'm having some problems in persisting the viewstate on postback for a Control (vb.net) here's some code i've put in my control: Protected Overrides Sub OnInit(ByVal e As System.EventArgs) MyBase.OnInit(e) Me.EnableViewState = True Me.ViewStateMode = System.Web.UI.ViewStateMode.Enabled If Not Page.IsPostBack Then _SortTime = DateTime.Now _SortTime.AddSeconds(-10) ' incase the fileserver and webserver date are out of sync ViewState("PageLoadTimeStamp") = _SortTime End If End Sub onload:

问题 I have an asp.net web page with a ton of code that is handled in the Page-Load event of the page. I also have a dropdown box on the page that should reload the page with a new value, but I would like to get this new value before I process the entire Page-Load code. I am trying to get my head around ASP.NET page lifecycle. Should I move the Page-Load code to a later event or is there a way to get the value of the dropdown list value before the the Page-Load event begins? TIA 回答1: I would use

问题 Here's my code : <form name='frm' id='frm' action='load.asp' method='post' onSubmit='return OnSubmit(this)' style='margin-top:15px'> <input type='submit' name='send' id='send' onclick="this.disabled=true;return true;" value='Send' title='test'> </form> I want my onsubmit function to be executed and I want the page to be submited. In my website, no submit and no function I've tried to duplicate it here, but the form seems to be posted and my function never gets executed ... http://jsfiddle.net

问题 Im running an ASP.NET 4.0 project. The .aspx page has AutoEventWireup="true" set in the header. Although OnPreInit is called, Page_PreInit is not? Can anyone suggest what is wrong? protected void Page_PreInit(object sender, EventArgs e) { Response.Write("bar"); } protected override void OnPreInit(EventArgs e) { Response.Write("foo"); base.OnPreInit(e); } 回答1: The Page_PreInit event does fire, you can see this, if you put a breakpoint at the start of the event and step through it at the run

问题 I've got an issue with nested controls not loading properly. I've tried various page methods and nothing seems to work. EDIT: The site compiles and runs fine--it just leaves a blank screen though. Basically I have a wrapper control for a Chart that allows me to select data, bind, and customize the chart with a lot of abstraction. I need another wrapper control for that because there may be groups of charts that I want to represent easily. Generalized answers would be great too. Here's what I

问题 I'm very new to ASP.NET and, after beating my head on a few problems, I'm wondering if I'm doing things wrong (I've got a bad habit of doing that). I'm interested in learning about how ASP.NET operates. My question is: Where can I find documentation to guide me in deciding where to do what processing? As a few specific examples (I'm interested in answers to these but I'd rather be pointed at a resource that gives more general answers): What processing should I do in Page_Load ? What
