思路,在模态窗口页面放一个影藏的iframe。
首先,我们新建一个模态窗口,在模态窗口a.aspx
后台代码:
处理文件下载页面DownLoad.aspx,页面代码不写,在后台代码写:
OK,完成,这样可以解决模态窗口点击下载链接没反应,或者弹出提示等等一些问题。

后台代码:
- protected void ibDownLoad_Click(object sender, EventArgs e)
- {
- string filePath = Server.MapPath("\\PDF\\a.txt");
- download.Attributes["src"] = "DownLoad.aspx?filePath=" + filePath;
- }
protected void ibDownLoad_Click(object sender, EventArgs e) { string filePath = Server.MapPath("\\PDF\\a.txt"); download.Attributes["src"] = "DownLoad.aspx?filePath=" + filePath; }
处理文件下载页面DownLoad.aspx,页面代码不写,在后台代码写:
- protected void Page_Load(object sender, EventArgs e)
- {
- string filePath = Request.QueryString["filePath"];
- //string filePath = Server.MapPath("\\PDF\\a.txt");
- if (File.Exists(filePath))
- {
- FileInfo file = new FileInfo(filePath);
- Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8"); //解决中文乱码
- Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(file.Name)); //解决中文文件名乱码
- // Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
- Response.AddHeader("Content-length", file.Length.ToString());
- Response.ContentType = "appliction/octet-stream";
- Response.WriteFile(file.FullName);
- Response.End();
- }
- }
protected void Page_Load(object sender, EventArgs e) { string filePath = Request.QueryString["filePath"]; //string filePath = Server.MapPath("\\PDF\\a.txt"); if (File.Exists(filePath)) { FileInfo file = new FileInfo(filePath); Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8"); //解决中文乱码 Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(file.Name)); //解决中文文件名乱码 // Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name); Response.AddHeader("Content-length", file.Length.ToString()); Response.ContentType = "appliction/octet-stream"; Response.WriteFile(file.FullName); Response.End(); } }
