处理网页之间的事件.. [英] handling events between webpages..
本文介绍了处理网页之间的事件..的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在创建一个web应用程序，我的设计要求创建
主要webform，左侧有菜单栏，IFrame有
将包含单击菜单项时显示的所有表单。除此之外
这些我想放置一个自定义状态栏。在任何网页中遇到的任何错误消息
都将显示在横幅中。
我遇到的问题是如何访问客户状态栏
显示在IFRAME中的子表单。我不能使用
HttpApplicationState.Application对象，因为我无法将自定义对象放在
应用程序对象中。那是对的吗？此外，假设我可以在遇到错误时从表单中提升事件
，那么问题是我如何在我的主框架中捕获该事件。我不想在我的主要表单中注册大量的事件
我的应用程序中有大量的对象。由于我不能在这篇文章中附上word文档所以我会尝试使用下面的数字
来证明我打算完成的工作：
主要网页（包含IFRAME，菜单栏，状态栏控制）
________ | _________
| |
Page1第2页（包含webcontrols）
|
Page1.1（包含webcontrols）
假设主网页显示iframe中的page1，当点击某个命令按钮并且页面1.1包含网页用户
控制时，它会显示
page1.1。现在假设用户在webcontrol中遇到了一些错误。我希望
该错误信息显示在主网页的状态栏控件中。
我可以从webcontrol引发错误事件，该事件将由Page 1.1，
剩下的问题是如何将该事件传播到主网页。
关于这种方法的任何建议或任何更好的方法来处理这个问题。我知道有没有办法在网页之间移动控制，但我找不到那个非常优雅的解决方案来解决我的问题。
谢谢

Hi,
I am working on creating a webapplication and my design calls for creating
main webform which will have menu bar on left hand side and a IFrame which
will contain all the forms that are shown when menu items are clicked.Besides
these i would like to put a custom status bar. Any error message encountered
in any of the webpage will be displayed in the banner.
The problem iam encountering is how to access the customer status bar in
child forms that are displayed in the IFRAME. I cannot use
HttpApplicationState.Application object as i cannot put custom objects in
application object. Is that correct? Also, assuming that i can raise events
from the forms when error is encountered then the question is how do i
capture that event in my main frame. I don''t want to register tons of events
in my main form for tons of objects that are there in my application. Since i
cannot attach word document in this post so i will try use following figure
to demonstrate what i am planning to accomplish:
Main Webpage(contains IFRAME, MENU BAR, STATUS BAR CONTROL)
________|_________
| |
Page1 Page 2(contains webcontrols)
|
Page1.1(contain webcontrols)
Assuming that main webpage shows page1 in the iframe which brings up
page1.1 when some command button is clicked and Page 1.1 contains web user
control. Now assuming user ecounters some error in the webcontrol. I want
that error message to be displayed in the status bar control of Main webpage.
I can raise error event from webcontrol which will be captured by Page 1.1 ,
the problem that remains is how to propogate that event to Main webpage.
Any suggestion on this approach or any better approach to handle this. I
know there is way to move control between webpages but i don''t find that very
elegant solution for my problem.

推荐答案
使用HTMLTable代替框架，放置不同的用户或自定义
控件来实现页面的各个组件。如果你担心在b / b
回发后必须重新创建所有组件的性能，那么请利用ASP.NET中的页面片段缓存功能
2.0。 http://beta.asp.net/QUICKSTART/ aspne ... / fragment.aspx
您是否有任何特殊原因需要使用框架？

Instead of frames, use an HTMLTable to place different user or custom

worried about the performance of having to recreate all components upon
postback then take advantage of the Page fragment caching feature in ASP.NET

Are there any particular reasons you want to use frames?
