Question

In an ASP.NET 3.5 application, I have created an ashx handler as below:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.IO; using System.Web.Services;  namespace TestWebConfig {     [WebService(Namespace = 'http://tempuri.org/')]     [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]     public class Handler1 : IHttpHandler     {          public void ProcessRequest(HttpContext context)         {             context.Response.ContentType = 'image/jpg';             BinaryReader br = new BinaryReader(File.Open( @'d:\Temp\images\AutumnLeaves.jpg', FileMode.Open ));              int bufferLength = 1000;              do             {                 byte[] buffer = br.ReadBytes(bufferLength);                 context.Response.OutputStream.Write(buffer, 0, buffer.Length);                 if (buffer.Length < bufferLength)                 {                     break;                 }             } while (true);             br.Close();         }          public bool IsReusable         {             get             {                 return true;             }         }     } } 

In an aspx page, if I specify:

<img alt='alt2' src='Handler1.ashx' style='border-width:0px'/> 

then the web page is loaded into the browser together with the image. On the other hand, if I use:

<asp:Image ID='Image2' runat='server' /> 

and in code-behind:

protected void Page_Load(object sender, EventArgs e) {    Image2.ImageUrl = 'Handler1.asxh'; } 

then the Image2 control does not load the picture, although the associated html code looks alike. Only the alt text is shown. What’s wrong?

Thanks

For one thing in your Page_Load it looks like you’ve given it the wrong extension, but I don’t think that’s the problem.
