I need displaying my image file stored from my database into the image control. I've had read some articles and watch video tutorial which there were perfectly working and I followed it but I wasn't able to make it work. The image control just displayed blank. I used Generic Handler to retrieve the image file from my database based on the articles and tutorials I've got. here are my codes below:
Generic Handler:
Code:
<%@ WebHandler Language="C#" Class="ShowImage" %>
using System;
using System.Configuration;
using System.Drawing;
using System.Drawing.Imaging;
[Code] ....
Asp.Net Code for the Image control:
HTML Code:
<asp:Image ID="Image1" runat="server" ImageUrl='<%# "ShowImage.ashx?ID=" + Eval("ID") %>' Height="128px" />
I return array of images ( System.Drawing.Image[] ) from database and i want to show them in datagrid or datalist .. how to do that ?
