Hi experts,

I have a webform wich contains a httppostedfile to upload file. I also have several dropdownlists on the page which will trigger auto-postback event.

My problem is, when the postback event is triggered, the text in the "textbos" of the httppostedfile will disappeared. I've already set the enable viewstate to true, however, the text still disappeared.

Could anyone tell me how to solve the problem?

Many thanks!!!
