I have a fileupload control in a contentplaceholder in a masterpage. I have to preview the image whenever I browse an image beside it in an imagecontrol.
My application is running on a different server .So I can't give the filepath of my local system.
Also I don't want to store the image in any location and i'm not supposed to use any session variable to pass it to generic handler.

my application is running in visual studio 2005, i used ajax control toolkit for .Net framework 2.0.but now i want to use ajaxcontroltoolkit latest version which is for .net framework 3.5 in my application which is running on .net framework 2.0 and visual studio 2005.how to integrate or use ajaxcontrol toolkit ?because i have some functionality like there is one file upload control and when click button it will take 2 to 3 min for upload so i need progress bar with loading gif file.because of asynchronous postback fileupload control has not file.so i must assign postback trigger to button if i assign postback trigger to button than loading gif or progress bar not working.so i want to use AsynchFileUpload control of newly release toolkit.

I've been tasked with creating a page where the user can do the following in this order:
1. browse to and select a jpg image 2. preview the image that the user just selected 3. if the user is happy with the preview then click the GO button to load the image to the Image folder.Does anyone have any good examples or sample code of how to do this?
I've got a plain C# web page that uses jQuery to call a handler page using AJAX. While the handler content is loading, a message "Please Wait, loading..." is displayed. Once I've got the content back from the handler I hide the loading message and display the content.What I'd like to do is after the loading message, display a percentage of how far through the handler page is. All the handler page does is loop through a list of members, powered by a web service, and adds them to the database so I know exactly how many members are being added to the database so I can tell how far I am through.The problem I'm having is because all of this goes on in a handler, how can I send the progress percentage back to the main web page while the handler was still loading.Any ideas? If I could do the exact same task but differently which would allow me to create the progress bar,
I'm trying to make a progress bar that updates the user on the progress of the AJAX call.
My immediate thinking was that I need an AJAX call to start a thread on the server, allowing the starting AJAX call to finish, and allowing the thread to send updates back to the user.
For the purpose of simplicity, disregard the actual progress bar functionality (I was thinking of implementing one of those JS bars, with fancy colors and effects ;), but if I can get an update from the thread, then updating a simple JS progress bar becomes trivial ;) )
I have a wierd issue with the update progress control in ie8. I have a modal popup that loads a pdf in an iframe, then i have a button click that navigates away from the pdf and shows a form in the same modal. All this is wrapped in an update panel, which i have an update progress control associated with. The control shows correctly in ie7, firefox, safari, and chrome. But in ie8 when the async post back is complete the progress indicator does not hide, until I click on the screen or scroll the page, then it hides and the form shows.
look at the picture, i want that image preview will come when i choose the file location before uploading to the database. is it possible?
EDIT: i found codes in other sites, they say those only work in IE, so it means currently, this preview function doesnt support FF? coz im using FF or sometimes google chrome.
I have to implement an image upload functionality in asp.net. The method I have followed works like this :-
Submit a form containing an <input type='file'> element and set the target of the form to a named iframe[to give the impression of a Ajax request/response ]. The aspx file which this form is posted to, writes the image into the response as Reponse.Write("<img src='location'/>"); The image displayed is due for cropping (where i plan to use JCrop).
What I would like to know is : Is there another way to display the image in a <div> may be, rather than in an iframe which I think is far better than this approach.
