问题描述
我的方法需要刷新以便为用户显示上传的照片。如何避免为用户刷新页面。
protected void fileUploadComplete（object sender，AsyncFileUploadEventArgs e）
{
Thread.Sleep（1000）;
尝试
{
string profileimg =，name =，formid =，ext =;
if（Session [DisplayName]！= null && Convert.ToString（Session [DisplayName]）！=&& Session [FormId]！= null && Convert.ToString（Session [FormId]）！=）
{
name = Convert.ToString（Session） [DisplayName]）;
formid = Convert.ToString（Session [FormId]）;
profileimg = Convert.ToString（ConfigurationManager.AppSettings [ProfileImg] ]）+ name.Split（''）[0] +_+ formid;
if（fileUpload1.HasFile）
{
ext = System.IO.Path.GetExtension（fileUpload1.FileName）;
位图bmpImg = null;
newfilenameWithExt = profileimg + ext;
if（hdnOldFileName.Value！=）
{
string oldFilePath = Server.MapPath（〜/）+/ storedata /+studentphotos / + hdnOldFileName.Value;
FileInfo oldFile = new FileInfo（oldFilePath）;
if（System.IO.File.Exists（oldFilePath））
System.IO.File.Delete（oldFilePath）;
}
StudentApplication objStdFileUpload = new StudentApplication（）;
objStdFileUpload.StudentFormID = 0;
objStdFileUpload.StudentFormID = Convert.ToInt32（Session [FormId]。ToString（））;
objStdFileUpload.StudentProfileImage = newfilenameWithExt;
if（objStdFileUpload.StudentFormID！= 0）
{
objStdFileUpload。 UpdateFileNameUploadByFormID（）;
//在上传到Storedata之前调整图像大小
bmpImg = Resize_Image（fileUpload1.PostedFile.InputStream，350,262） ;
bmpImg.Save（Server.MapPath（〜/）+/ storedata /+studentphotos /+ newfilenameWithExt，ImageFormat.Jpeg）;
hdnFileNmWithoutExt .Value = Convert.ToString（ConfigurationManager.AppSettings [Home]）+storedata / studentphotos /+ newfilenameWithExt;
imgStudentImage.ImageUrl = Server.MapPath（〜/ storedata / studentphotos / ）+ newfilenameWithExt;
}
}
}
}
catch（exception ex）
{
MessageControl1.ErrorMessage（Error： - + ex.ToString（））;
}
}
My Method requires refresh in order to show uploaded photo for user.How to avoid refreshing of page for user.
protected void fileUploadComplete(object sender, AsyncFileUploadEventArgs e)
{
Thread.Sleep(1000);
try
{
string profileimg = "", name = "", formid = "", ext = "";
if (Session["DisplayName"] != null && Convert.ToString(Session["DisplayName"]) != "" && Session["FormId"] != null && Convert.ToString(Session["FormId"]) != "")
{
name = Convert.ToString(Session["DisplayName"]);
formid = Convert.ToString(Session["FormId"]);
profileimg = Convert.ToString(ConfigurationManager.AppSettings["ProfileImg"]) + name.Split(' ')[0] + "_" + formid;
if (fileUpload1.HasFile)
{
ext = System.IO.Path.GetExtension(fileUpload1.FileName);
Bitmap bmpImg = null;
newfilenameWithExt = profileimg + ext;
if (hdnOldFileName.Value != "")
{
string oldFilePath = Server.MapPath("~/") + "/storedata/" + "studentphotos/" + hdnOldFileName.Value;
FileInfo oldFile = new FileInfo(oldFilePath);
if (System.IO.File.Exists(oldFilePath))
System.IO.File.Delete(oldFilePath);
}
StudentApplication objStdFileUpload = new StudentApplication();
objStdFileUpload.StudentFormID = 0;
objStdFileUpload.StudentFormID = Convert.ToInt32(Session["FormId"].ToString());
objStdFileUpload.StudentProfileImage = newfilenameWithExt;
if (objStdFileUpload.StudentFormID != 0)
{
objStdFileUpload.UpdateFileNameUploadByFormID();
// Resize Image Before Uploading to Storedata
bmpImg = Resize_Image(fileUpload1.PostedFile.InputStream, 350, 262);
bmpImg.Save(Server.MapPath("~/") + "/storedata/" + "studentphotos/" + newfilenameWithExt, ImageFormat.Jpeg);
hdnFileNmWithoutExt.Value = Convert.ToString(ConfigurationManager.AppSettings["Home"]) + "storedata/studentphotos/" + newfilenameWithExt;
imgStudentImage.ImageUrl = Server.MapPath("~/storedata/studentphotos/") + newfilenameWithExt;
}
}
}
}
catch (Exception ex)
{
MessageControl1.ErrorMessage("Error:- " + ex.ToString());
}
}
