How do i assign a file path to fileupload control after postback.

I am running Windows Server 2008 Datacenter, ASP.NET 4, IIS 7 and getting the error :Access to the path <path> is denied when using the FileUpload control to save the uploaded file to this directory.I have given the directory in question full access to Network Service but that makes no difference.I have even given the directory full access to Everyone but it still gives the same error.Totally baffled by it

I hope can remain the path in the FileUpload control during postback.

I'm using five FileUpload controls on a single web form. Besides allowing the user to upload a file I also am collecting user data. Problem I run into is during the server side validation if any of the user data is invalid on a post back when content it redisplayed the FileUpload controls loose the client url that was selected when browsing. How can I keep that path or set the pathing on the control so they do not have to keep rebrowsing for the files on data validation errors? Right now breaking up the two form sets user data and file upload into two pages is being frowned upon and requirments would like it to be on all one page.
The requirement is that the whole original file path be saved to the database; for example: L:folder1folder2xyz.doc. However; the FileName property of the FileUpload control will only give "xyz.doc". We are interested in obtaining the full path only and really not interested in using the control to do any upload.
Is there any way to get the full path? We would like our user to be able to browse to the target file instead typing into a textbox because the folder name could be very long and several levels deep in our organization.
I have a situation where I want a user to select a file, then select an option from a DropDownList. When they select an item from the DropDownList I do an auto post back and do some stuff with the file, but this causes the path to clear out. Is there some way that I can keep the path from clearing out?

I created a virtual directory in the Visual Web Developer, according to this post:
[URL]
I want the user to upload / download documents in the mvc app to that virtual directory. When a document is uploaded, I'm specifying the path to the document to be stored for later retrieval like so:
~/VirtualDirectoryName/FileContent.docx. But when I try to open that as a link in th app,using ResolveUrl, it appends the port number after localhost like so,[URL], I get a document not found, since it really should be, [URL].
I'm trying to use an asp:FileUpload Control to allow users to upload files (.doc, .gif, .xls, .jpg) to a server that is outside of our DMZ and not the Web Server. We want to have the ability to look at these files for viruses, structure, etc prior to saving them into another directory that would allow access to outside users. From what I have read about this control is that it will allow for files to be uploaded to the web server. Can this control be used to upload files to a server other than the web server? If it can be done where should I look for this type of functionality or how do I force it to go to https:servernamefolder name (Where server name is not the web server)? Would I have to read the file then write it to the other server?
how can we save the uploaded file path in to database and then retrieve it in gridview as a link so when user click on that it will open that file in browser.
