I have a project.i am using a file uploader, i want to preview the image in a panel or div what i selected in the fileuploader control, what is the solution?

1 solution

add a httphandler class

<%@ WebHandler Language="C#" Class="ImageHandler" %>

using System;
using System.Web;

public class ImageHandler : IHttpHandler, System.Web.SessionState.IRequiresSessionState

   public void ProcessRequest (HttpContext context) {
    //Checking whether the imagebytes session variable have anything else not doing anything

       if ((context.Session["ImageBytes"]) != null)
           byte[] image = (byte[])(context.Session["ImageBytes"]);
           context.Response.ContentType = "image/JPEG";

   public bool IsReusable {
       get {
           return false;


and in the preview button click
protected void btnPreview_Click(object sender, EventArgs e)


       Session["ImageBytes"] = PhotoUpload.FileBytes;

       ImagePreview.ImageUrl = "~/ImageHandler.ashx";


Here PhotoUpload is my File Upload control and ImagePreview is asp:image control.
