ModalPopupExtender Show（）没有触发ASP.NET C＃ [英] ModalPopupExtender Show() not firing ASP.NET C#

问题描述

我知道这个问题已经发布在很多不同的场合。我看了很多网站找到这个问题的解决方案，但是这些解决方案都没有帮我找到正确答案。



我的代码基于在这个人的网站上>>

http://mattberseth.com/blog/2007/07/modalpopupextender_example_for.html [ ^ ]



我有一个GridView，它从SqlDataSource1中获取数据。在GridView中，在第一列中我有View按钮，它们应该显示ModalPopupExtender1中每行的详细信息。我将其TargetControlID设置为btnShowPopup，这是不可见的，但正如我所说的不可见并不意味着它设置为Visible =false但它设置为style =display：none（我发现这是人们做的方式）。



问题是即使我点击其中一个View按钮，ModalPopup也没有出现。实际上，当我单击按钮时，没有任何反应。



在Visual Basic上，单击查看按钮后，我看不到任何错误消息或异常处理程序。



任何帮助将不胜感激。提前谢谢！

I know this issue has been posted on many different occasions. I've looked so many websites to find a solution to this issue, however none of those solutions have helped me find the correct answer to this.

My code is based on this guy's website>>
http://mattberseth.com/blog/2007/07/modalpopupextender_example_for.html[^]

I have a GridView that sources its data from the SqlDataSource1. Within that GridView, in the first column I have View buttons that should show the details of each row in the ModalPopupExtender1. I set its TargetControlID to btnShowPopup, which is not visible but as I say "not visible" doesn't mean it's set Visible= "false" but it is set style="display:none" (I found this is the way people do).

The problem is even when I click on one of the View buttons, the ModalPopup doesn't appear. In fact, when I click the button, nothing happens.

On the Visual Basic, I don't see any error messages nor exception handlers after clicking on the View button.

Any help would be appreciated. Thank you in advance!
