我的网站有问题。

有一个按钮可以打开 Crystal Reports 文件。大多数情况下，它会正确加载，但有时它不会加载任何内容。

我注意到，如果我在主页加载后立即单击按钮并打开报告，它不会加载（即使您尝试刷新或重新加载报告）。如果您等待至少 3 秒钟并按下按钮，则报告会正确加载（通常在我打开报告时工作，不加载，关闭窗口，再次按下按钮，它会正确加载）。

我知道这听起来像一个愚蠢的问题，但任何用户总是报告文件没有打开，并最终放弃使用我的系统。我需要找出如何修复这个问题，我可以从哪里开始？

使用 ASP.Net 中的 Crystal，我在 Page_Init 而不是 Page_Load 事件中加载报表。此外，关闭和处置清理在 Page_Unload 事件中处理。

我注意到 Web 应用程序启动后的第一个报告需要相当长的时间来加载这是 Crystal 运行时。第一次加载后，一切都很好。IIS 在空闲时间后关闭 Web 应用程序后也会发生这种情况。

您唯一能做的就是预热水晶运行时。一种选择是在您的应用程序启动时执行此操作。甚至这意味着从您的 global.asax 在 Application_Start 调用一个虚拟的空白水晶报告。
