Question

iv’e got a repeater bonded to a list of entities

    BL_Engine engine = (BL_Engine)Application["engine"];
    List<AppProduct> products = engine.Get_Products();
    Repeater1.DataSource = products;
    Repeater1.DataBind();

iv’e also got a user control i use to represent these product entities , i do this by overriding the Databind() in the user control :

    public override void DataBind()
    {
        AppProduct product = (Page.GetDataItem() as AppProduct);
        lbl_title.Text = product.Title;
        lbl_short.Text = product.Short;
        lbl_date.Text = product.Date.ToShortDateString();                       
        Session["current_img"] = product.Image1;            
        base.DataBind();
    }

in my HttpHanlder object kept in a .ashx file i write the image to the response
the response happens only once so only the last picture is written to (ALL) the user controls.

     public void ProcessRequest(HttpContext context)
     {
        byte [] image = (byte[])context.Session["current_img"];                  
        context.Response.ContentType = "image/bmp";
        context.Response.OutputStream.Write(image, 0, image.Length);
     }

any idea how i could write the binary data for each individual control

thanks in advance

Let me suggest a different approach.

Declare a regular html image element in your control and set the “runat=server” property as so:

<img src="" runat="server" id="img_product" />

Then change your DataBind() method to do this instead:

 public override void DataBind()
 {
       AppProduct product = (Page.GetDataItem() as AppProduct);
       lbl_title.Text = product.Title;
       lbl_short.Text = product.Short;
       lbl_date.Text = product.Date.ToShortDateString();                       
       img_product.src= "\"data:image/jpg;base64,"+System.Convert.ToBase64String(product.Image1)+"\"";
        base.DataBind();
 }

And get rid of the HTTPHandler. You don’t need it for this.
