MVC3 导出Excel 问题，急急急！！！！
1.后台从数据库取出数生成FileResult，正常情况下浏览器可直接导出excel了但是现在想控制View层的按钮，点击导出按钮后禁用按钮，等事件完成再启用就出问题了。
后台代码：
[HttpPost]
public FileResult Index(ReportModel model)
{
if (!model.ReporType.HasValue)
{
return null;
}
byte reportTypeValue = 0;
string reportName = string.Empty;
ReportType accountMaster = _reportService.GetReportType(model.ReporType.Value);
if (accountMaster == null)
{
return null;
}
else
{
reportTypeValue = accountMaster.Id;
reportName = accountMaster.Name;
}
byte businessTypeValue = 0;
string businessName = string.Empty;
if (model.BusinessType.HasValue)
{
businessTypeValue = model.BusinessType.Value;
businessName = _reportService.GetReportBusinessName(reportTypeValue, businessTypeValue);
}
var getUser = GetUser();
ReportSearchCondition rsc = new ReportSearchCondition
{
ReportName = reportName,
BusinessID = businessTypeValue,
BusinessName = businessName,
BeginTime = model.BeginTime.Value,
EndTime = model.EndTime.Value.AddMilliseconds(997),
OperaterID = getUser.UserCode,
OperaterName = getUser.UserName
};
Func<ReportSearchCondition, DataSet> func = GetReportMethod(reportTypeValue);
string fileName = string.Format("{0}从{1}到{2}",
rsc.BusinessID == 0 ? rsc.ReportName : rsc.BusinessName,
Convert.ToDateTime(rsc.BeginTime).ToString("yyMMdd"),
Convert.ToDateTime(rsc.EndTime).ToString("yyMMdd"));
ExportDataToExcel(func, rsc);
return File(fileName, "application/vnd.ms-excel");
}
2.前台通过Ajax.BeginForm来异步控制，onbegin就执行startFunc脚本禁用导出按钮，onsuccess就
执行completeFunc启用导出按钮，但是这个时候，浏览器就不再出现下载EXCEL文件的提示了！！
整了一天，希望有高手指点。顺便说下Ajax.BeginForm 的 UpdateTargetId="Result" 能把报表结果导出到
id=result这个div下面展示到页面，就是TM不出现下载文件。
