这听起来可能非常复杂，所以请留在我身边。
我有一个页面，我调用了一个更新面板，并根据客户端点击的表格行使用jQuery手动刷新。
这会显示一个新的更新面板。
这是按预期工作但我注意到它在点击后发出控制台错误
Uncaught TypeError: Cannot call method 'get_dataItems' of undefined ScriptResource.axd:5679
我尝试将更新模式设置为条件并从后面的代码中调用它，并尝试在更新面板上设置触发器，但收到cannot find control错误。
我也尝试过异步回发。
我想知道是否有人能想到可能的解决方案。

再次不得不删除一些主要是dll调用。
