using ASP.net, vs2008 C#.

Im using a FileUpload control on a webform. The uploading of a file (ie PDF dcouments) to a server directory works ok.

I have on the webform a "preview" button that the user can use to preview the PDF file after they have selected it via the Fileupload browse feature. I do this by

if (this.FileUpload1.HasFile) { localURL = FileUpload1.PostedFile.FileName; // use this to preview file. Other methods are restricted by local security requirements Process.Start(localURL); }

My problems is that after the button click Postback occurs the location of the selected file disappears from the textbox part of the Fileupload control.

How can i keep this info there, so the user does not have to browse again and instead can just click upload to upload the file.

Any help appreciated

thanks
