Keep Fileupload data on change NOT Postback

Hi

I'm writing a multi image upload page. The FileUpload control loads the images and displays them in a preview.

The user can then click an image, to remove it, which populates a list I will loop through on PostBack to make sure the deselected images are not saved to my server.

So I choose images 1 to 5 and remove image 4 and 5.

My problem is after they've deselected image 4 and 5 they might want to add one or two other images. The person clicks browse to add more images , this then removes the images already selected, image 1 to 3. Is there a way to keep images 1 to 3 that I first selected and just add to them when the user clicks the FileUpload browse button again.

So nothing is submitted this is all before the post.
Thanks

Hi peter,

Your issue is postback which is causing the image reset.
If you have fixed number of fileuploads u can create 5 session variables for image binary data as well as its status.

Reload from those variables on postback if they are not null.

hope it helps.
Thank you.
