我做了一个自定义绑定Grid,Grid和几个提交值的textbox是放在UpdatePanel里的,但是我提交的时候会弹出一个对话框报sys.webForms.PageRequestManagerParserErrorException:The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(),response filters, HttpModules, or server trace trace is enabled.Details:Error parsing near ' |<html> ,. <head>
不知道什么原因,我的cs提交数据的BUTTON事件是:
protected void BtAddItem_Click(object sender, EventArgs e)
{
DataSet ds = new DataSet();
DataRow dr;
DataTable dt;
if (Session["Table"] == null)

异步更新的代码经过特殊的处理.后台识别不了

你不传session 试试。
具体分析参考如下(来源网上):
ASP.NET中使用AJAX后，Session丢失异常的自定义处理。ASP.NET中使用AJAX后，如果客户端长时间没有操作或者服务器原因丢失Session，会弹出类似以下的英文错误信息，对于用户没有实际提示作用。为了有更好的用户体验，我们希望能够自定义这个异常。
引用内容Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near '下面提供一个很简单的办法，使用ScriptManager的EndRequestHandler事件。将以下Javascript加入到<ScriptManager>标签后面，注意不能放在<Head>中。
程序代码<script language="javascript"> Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function EndRequestHandler(sender, args)
{
if (args.get_error() != undefined)
{
if(args.get_error().message.substring(0, 51) == "Sys.WebForms.PageRequestManagerParserErrorException")
{
window.location.reload(); //出现Session丢失时的错误处理，可以自己定义。
}
else
{
alert("发生错误!原因可能是数据不完整,或网络延迟。"); //其他错误的处理。
}
args.set_errorHandled(true);
}
}
</script>
Response.Write()
Response.......
ScriptManager.RegisterStartupScript(this.UpdatePanel1, this.GetType(), "updateScript", "alert('保存成功');", true);
<Triggers>
<asp:PostBackTrigger ControlID="btn_Login" />
</Triggers>
用这个指定一下你的按钮就好使了
