How To Pass A Raw System.Drawing.Image To An .ashx
Jun 4, 2010I am developing an application that stores images as Base64 strings in xml files. I also want to allow the user to crop the image before saving it to the file, preferably all in memory without having to save a temp file, and then delete it afterwards. In order to display the newly uploaded image, I need to create a HTTP handler that I can bind the asp:Image to. The only examples for doing this online require passing the .ashx an ID and then pulling the image from a DB or other data store. Is it possible to somehow pass the raw data to the .ashx in order to get back the image?

View 3 RepliesAshx Vs Aspx For File Download
Dec 15, 2010In a basic scenario where I have a GridView with files to download and link buttons to download them, is there any benefit at all for creating a custom http handler for streaming those files as opposed to simply streaming from the event handler of the download link button?
Edit: As some suggested code reuse would favor the handler, however it's not an issue in this particular case. The handler is also faster being that it avoids the page life cycle, however this slight performance improvement is probably not worth creating a handler for in my particular situation. The only thing that comes to mind now is (assuming using the same aspx page approach) whether there is any special consideration in a situation where the GridView is inside an UpdatePanel?

Aug 20, 2010I have an Handler.ashx file and on .aspx page load it calles the .ashx file for image reading. I am attempting to pass a session from the .aspx file to the .ashx file in order to make my query of grabing the image secure. The problem is that everytime I call a session: HttpContext.Current.Session["ID"], the value is returning null or errors saying the o so commong "Object reference not set to an instance of the object". I have tried a couple ways of grabing the session:
1.) context.Session["ID"]
2.) HttpContext.Session["ID"]
3.) HttpContext.Current.Cache["ID"]
none of them are giving me the ID session set in the .aspx page. should i be using Server.Transfer instead? is there a way to grab a session variable set in a .aspx page and called in a .ashx page?

Web Forms :: Pass Values Between .aspx Pages?
Mar 28, 2011I've got a pretty simple problem but I am not sure what is the best way to accomplish this. I've got an input aspx where a user fills in about 15-20 input fields and I want to display this information on the next page however; I am not really sure what is the best way to go about doing this?
I tried using 'Server.Transfer' and 'FindControl' API calls but have struggled to use them because the value is always null because it cannot find the asp:textbox ID I have specified from the previous page.
What would be the best way to just simply transfer the values from my previous page to the next page??
