用户控件错误处理 [英] User controls Error Handling

问题描述

我想知道是否有一种方法可以在用户控件上运行，如果可以抛出异常，则可以代替显示错误页面以便继续加载页面，但是在位置显示消息用户控件应该是

我正在尝试的操作比try catch稍微复杂一些，对于所有未处理的异常，它必须是通用的，因此，例如，如果数据源控件丢失了与数据库的连接.我也知道gobal.asax中的全局错误处理，但是我的目标是单独处理单个用户控件上的错误.

I would like to know if there is a way to on a user control , if an Exception is thrown if it is possible to instead of showing an error page for the page to continue loading but show a Message in the place of where the user control is supposed to be

What I am attempting is a little bit more complex than try catch, this has to be generic for all un-handled exceptions, so if for instance a data-source control lost connection to a database. I also know about global error handling in gobal.asax , but I am aiming to individually handle errors on individual user controls.

如果我正确理解了您的问题，那么您可以使用" Try-Catch "块来捕获您的异常，然后向最终用户显示适当的消息.
