Question

我有一个母版页，它们是脚本管理器，里面有更新面板。。现在我尝试在内容页面中添加更新面板而不使用脚本管理器，但它给了我一个错误：

The control with ID 'updpanel' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

我知道我只能使用一个脚本管理器实例，然后我尝试了 ScriptManagerProxy ，但它给了我一个scriptMangerProxy需要脚本管理器的错误。我也试过ajax：ToolScriptManager但它也给出了相同的结果所以问题是如何使更新面板在内容页面中工作..

Answer 1

您应该在更新面板上方的母版页中只有一个脚本管理器。

在任何内容页面中，您都可以使用更新面板，因为母版页中已有脚本管理器。你也应该为你的问题提供一些代码。

脚本管理器不起作用
