ASP.Net Final Rendering Page Event

问题 Perhaps my previous question on output caching output caching was too complex. Let's simplify. How can I get the final, "ready for sending" rendered HTML from a page (or control) event in ASP.Net? I assume that this will be the same content that will be used for the output cache, so could be queried to find out what is about to be placed into the cache. 回答1: Code copied from: http://aspcode.net/Last-second-HTML-changes-in-your-ASPNET-page.aspx protected override void Render(HtmlTextWriter

问题 I am new to C# and .Net and am coming from a Java background. I am trying to get my head around the .NET way of doing web applications and am not having much luck. I want to build an application to handle requests urls and write responses that return images. Having only used Java servlets in the web application field I am after some good resources and/or explanations on handling the request side of the application. How are requests handled? and with what Objects? What is the cycle? how do

Is there a function called anytime ANY page is loaded in your application?

问题 I want to be able to run a script anytime ANY page is loaded in the application. Is there somewhere I can simply add this? Or do I have to add the code in every page load? 回答1: You can do one of three things: Use a base page in your application, and have all the pages in your application inherit from it. In the page_load event in the base page, do what you have to do. Make sure that the inheriting pages in your app call the base page's page_load event if they override page_load (they usually

How to clear Session when navigating away from one page

拜拜、爱过 提交于 2019-12-06 15:50:31
I googled this about 1/2 a hour no hit's. Scenario is that, dynamic scripts are saved in string builder whose "string" representation is stored in session. It just happens that when user navigates away from one page to another the script[from session] gets registered using "RegisterStartupScript" . The script is registered in PreRender event of the Page. So i would like to clear this script in session while the page navigates away btw rule out a option to create another session variable and clear previous one. It's a overhead :( Why are you storing this in Session, do you need to maintain this

Page_PreInit not called?

给你一囗甜甜゛ 提交于 2019-12-05 05:54:43
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); } Denys Wessels 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 time. The reason the string "bar" is not being written to the screen is because it gets

ASP.NET Page life cycle: methods vs Events

元气小坏坏 提交于 2019-12-04 20:33:15
Can someone please explain to me the difference between methods and events in the ASP.NET page life cycle? Thanks When a page runs a series of methods are executed. These methods in turn raise events that can be handled by the user to perform various tasks like initializing controls, populating control properties, executing control behavioral code, etc. Here is an excellent flowchart from MSDN that shows the different methods that are executed, and the events that are raised from those methods: For more information about the ASP.NET Page Lifecycle, see the full overview on MSDN: http://msdn

what is the difference between postback data and view state data

不想你离开。 提交于 2019-12-04 04:06:59
I am trying to understand different events in a Asp.net page life cycle. I came across to this link . It has two stages Load view state and Load postback data. I used to thought that these both means the same thing. But this article says, that postback data is not viewstate data. I don't understand this. If anyone can have a look. R0MANARMY ViewState data is data that ASP.NET encoded end sent to the client in the _ViewState hidden field. It's basically the page as it was when it was sent to the client. PostBack data is data that the user submits. For example suppose you have a textbox on a
