带有日历控件的文本框在文件下载后不会在IE中显示日历图像。

确保已声明DOCTYPE

ClientScript.RegisterStartupScript(this.GetType(), "load", "HideProgress
();window.location.href='DownloadFile.ashx';", true);
Handler file:
public class DownloadFile : IHttpHandler, System.Web.SessionState.IRequiresSessionState
{

public void ProcessRequest (HttpContext context) {

        if (context.Session["fileContent"] != null && context.Session["filename"] != null)
        {
            //Download the excel file
            System.IO.StringWriter fileContent = (System.IO.StringWriter)context.Session["fileContent"];
            string filename = context.Session["filename"].ToString();
            context.Response.Clear();
            context.Response.ClearHeaders();
            context.Response.ClearContent();
            context.Response.ContentType = "application/vnd.ms-excel";
            context.Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
            context.Response.Write(fileContent.ToString());
            context.Response.Flush();
        }

}
与用户代理指示器一起告诉IE使用可用的最新渲染引擎

<!DOCTYPE html>
我应该在哪里包括这些内容？应该是您文件中的第一条语句，应该在beginsI之后立即包含。我对此表示怀疑，但大多数与IE相关的问题[JS和CSS]都可以通过此解决，希望它也能帮助您！
