how to enableviewstate on an input type=file

I have a form with a file input that allows users to browse local harddrive for images to upload.

On the same form I have an autopostback dropdownlist for categories, but when the event fires all the server controls maintain viewstate but the file inputs are cleared?

I tried adding runat=server enable viewstate = true
but that does not work.

I also set a hidden label with the file value, but I am unable to set the inputfile.value with the lable.text.

Does anyone have a solution. I really want the inputs to maintain their values, without having extra labels and extra work

Thanks
Matt

unomateo,
Normally what i'll do to solve this problems is create a separate upload page(pop-up), then you can keep the current uploaded file in temporarily directory. If everythings is finish to configure/set input, the uploaded file will be move to your desired location later(add some code to kill the temporarily files). That's how i solve this problems. Hope it helps.
