Dear,

I had the AJAX Uploader Control. I want some javascript code to be run before actually upload

file, this code is to check if the uploaded file from one of certain extesions then it will not be

uploaded otherwise upload the file

Note : I know that "AllowedExtension" list can be used, but it is too difficult to specify which

extensions to be uploaded also I do not need to upload the file then display an error message to

the user informing him that it is not allowed extension

Regards,

Tamer

Thanks
