我正在开发一个 ASP.NET Web 应用程序。我的一个在客户端机器上执行非常慢。在我使用 GridView 的地方，其中包括一些功能和一些控件，例如组合框输入框，每个控件都有一些功能和计算。

Please suggest me how can I improve this?

Page on content.

 - GridView
    1. Combobox with jquery datafiltering 
    2. Inputbox with data check function 
    3. More function of grid like update,add, new, delete.

I am also use Viewsate on this page.

这个问题有很多原因。据我从你的问题中理解，我会建议一些你需要看看的地方。

1）检查您从数据库中检索到的数据量，以便主要显示网格视图。

2）将上述控件添加到gridview不会使其性能不佳。但是您谈论的计算可能是一个原因。深入查看代码，检查是否有任何长时间运行的循环或其他东西那里。

3）如果前两个没有帮助您进行分析。对于您的问题，您只需要试用版的ant 性能分析器。安装配置文件后，找出哪个数据库调用或 .net 函数需要更多时间来执行，然后对其进行调试。
