我收到以下错误使用更新面板与gridview。如何从数据库获取BLOB值并将其存储在自定义对象中的字符串中？
Microsoft JScript运行时错误：Sys.WebForms.PageRequestManagerParserErrorException：无法解析从服务器收到的消息。此错误的常见原因是，通过调用Response.Write（），响应筛选器，HttpModules或服务器跟踪已启用来修改响应时。
我已经看过所有的“修复”，并没有人似乎工作。它在页面加载时工作得很好，但是当我点击我的异步按钮时，网格进程的一行（我可以在javascript调试中查看），但是在处理完第一行之后，我在此行发生上述错误。
try { _this._webRequest.completed（Sys.EventArgs.Empty）; } 如果（_this._xmlHttpRequest！= null）{ _this._xmlHttpRequest.onreadystatechange = Function.emptyMethod; _this._xmlHttpRequest = null; }}

我在这段代码中做的是从数据库中转换一个BLOB值并将其存储在一个自定义对象中的字符串中。似乎发生的事情是，在字符串的末尾放置了奇怪的字符。下面是我在做什么，以数据
byteBLOBData = (Byte[])(row[3]);
row["data"] = System.Text.Encoding.UTF8.GetString(byteBLOBData);
发布了更多问题，如果你可以看戴夫，谢谢！ – 2011-03-21 23:53:39
