asp wizard control- not retaining value of file upload control

Question

Hi I am developing a web application in asp.net and c#. I'm using an asp wizard control. there is 6 wizard steps in my wizard. In each phase im using many controls so that many postback is done during execution. I am using a asp fileupload control in second wizard step. My problem is that the value selected using fileupload control is not getting when i click wizard finsh button in the final step. values acquired using all other controls are available there. Hope someone help me. I just want to get the selected filename in last step. Thanks in advance

For security reasons the File Upload control does not save the posted file name in its View State so the file is lost on postback. Hide a Literal control behind the File Upload control. On postback if the File Upload control contains a file set the file name to the Literal control. Show the Literal control and hide the File Upload control. Save the posted file to a session variable since it will be needed when the record is saved Like this you can maintain the file names in your application till the wizard completes
