You need to post some code so we can see what is going on. Also, have you used a breakpoint to see if your updatepanel is doing a postback, the first time ?

Why don't you use Asynchronous FileUpload control ?

Try to avoid using FileUpload control inside UpdatePanel, as it involves post back problems with it. Use asynchronous file upload control instead. You can find a nice sample code here Asynchronous File Upload[^]
