Is there a file upload control for ASP.Net which performs a client-side checksum calculation (CRC, MD5, etc) on the file contents and transmits the checksum to allow for server-side checksum validation?
I have looked through answers on several file upload questions, but did not find this feature mentioned anywhere.
I am using the async file upload control to upload to a image file. I want the user to upload only jpg files. And for that I am checking the uploadedfile content type in server side, after the upload complets. I wanna check this, before upload starts. There is one javascript method
function startUpload(sender, args){}
but how to access the content type of the file selected by user.
I want to check the selected file size BEFORE uploading a file with the asp fileupload component.I can not use activex because the solution have to works on each browser (firefox, Chrome, etc..)How can I do that ?
