//把table控件中的数据保存到excel或word public void Save(System.Web.UI.Control source, DocumentType type)

//设置Http的头信息,编码格式 if (type == DocumentType.Excel) { //Excel Response.AppendHeader("Content-Disposition","attachment;filename=result.xls"); Response.ContentType = "application/ms-excel"; } else if (type == DocumentType.Word) { //Word Response.AppendHeader("Content-Disposition","attachment;filename=result.doc"); Response.ContentType = "application/ms-word"; }

Response.End(); }
//以下是保存图片 public void SavePic() { string path = Server.MapPath(".") + @"\images\Chart.jpeg"; FileStream file = File.OpenRead(path); byte[] content = new byte[file.Length]; file.Read(content,0,content.Length); file.Close();
Response.Clear(); Response.AppendHeader("Content-Disposition","attachment;filename=Chart.jpeg"); Response.ContentType = "image/jpeg";//设置Http的头信息 Response.BinaryWrite(content);//输出 Response.End(); }
不过图片保存完后,页面上的DropDownList的Select事件不能促发,不晓得是什么缘故,而页面上的button事件却可以激发事件,不知道大家有没有出现过这种问题?可以讨论一下,还是我保存图片的过程有问题?
