我得到一个按钮，点击下面的异常，对ASP页面，该页面在GridView在页面加载绑定500多条记录。

我的页面没有任何上传控制。它包含一个文本框，按钮和GridView控件。 有谁知道为什么发生这种情况。

异常说明：

 超过最大请求长度。
描述：在当前Web请求的执行过程中发生未处理的异常。请查看有关错误的详细堆栈跟踪信息，以及它起源于code。
 

解决方案

一个回发发回的每个控件的视图状态 - 如果你有一个庞大的数据网格，然后在浏览器转播，为服务器，这就是为什么你得到该异常。

您有两个选项：

增加 web.config中的最大请求大小，如下所示：

 ＆lt;结构＆GT;
    ＆LT;的System.Web＆GT;
        ＆LT;的httpRuntime maxRequestLength的=32768/＆GT;
    ＆LT; /system.web>
＆LT; /结构＆gt;
 

希望这有助于

I'm getting the following exception on a button click, for an asp page which binds more than 500 records in a gridview on page load.

My page does not have any upload control. It contains a textbox, button and the gridview. Does anyone know why this is happening.

Exception Description:

Maximum request length exceeded.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

A postback sends back the viewstate of every control - if you have a huge datagrid, then when the browser reposts that to the server, this is why you are getting the exception.

Your two options are:

Increase the maximum request size in web.config as shown below:

<configuration>
    <system.web>
        <httpRuntime maxRequestLength="32768" />
    </system.web>
</configuration>

Hope this helps
