问题描述
根据以下代码段，我有2个更新面板。虽然第一个被触发，但我无法触发第二个（更新面板以粗体突出显示并且下划线不可见），因此其中没有任何内容在页面上可见。我在内容模板后添加了一个触发器但没有任何成功。非常感谢任何帮助。
Hi,
I have 2 Update Panels as per the below code snippet. While the first is getting triggered, I am somehow not able to trigger the second one (Update Panel Highlighted in bold and underlined is not visible) and hence none of the contents therein are visible on the page. I have added a Trigger after the Content Template without any success though. Any help is much appreciated.

推荐答案
I can’t see any closing tag for your update panels like</ajax:UpdatePanel>
The most likely scenario is that asp is trying to fix this issue by adding closing tags, but in the wrong places. You need to close of both update panels in the markup:
