Microsoft JScript错误 [英] Microsoft jscript error

问题描述

大家好，
我单击了asp:Updatepanel中存在的btnDownloadWebConnector，并且在btnDownloadWebConnector_Click的情况下，我正在调用一个类似于以下
的函数 CodeBehind

Hi all,
I am clicking btnDownloadWebConnector that was present inside asp:Updatepanel and in event of btnDownloadWebConnector_Click i am calling one function like the following
CodeBehind

protected void btnDownloadWebConnector_Click(object sender, EventArgs e)
{
    string filename = Server.MapPath(@"~/ZSLWebConnect/ZSLWebConnectorSetup.msi");
    FileInfo fileToDownload = new FileInfo(filename);
    if (fileToDownload.Exists)
        {
        Response.ClearContent();
        Response.AddHeader("Content-Disposition", "attachment; filename=" + fileToDownload.Name);
        Response.AddHeader("Content-Length", fileToDownload.Length.ToString());
        Response.ContentType = "application/octet-stream";
        Response.TransmitFile(fileToDownload.FullName.ToString()); 
        Response.End();
        }
   }

单击执行上面的代码后，我得到了javascript错误:"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修改响应时到Response.Write()，响应筛选器，HttpModules或服务器跟踪已启用.
详细信息:解析"附近的错误.
谁能帮我解决以上错误吗?
预先感谢，
Bala.
