i m using following code as suggested by you but still the same problem persist.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If (Session("photoupload") Is Nothing And photoupload.HasFile) Then

Session("photoupload") = photoupload

'Label1.Text = FileUpload1.FileName;

'Next time submit and Session has values but FileUpload is Blank

' Return the values from session to FileUpload

ElseIf (Session("photoupload") Is Nothing AndAlso (Not photoupload.HasFile)) Then

photoupload = DirectCast(Session("photoupload"), FileUpload)

'Label1.Text = FileUpload1.FileName

' Now there could be another sictution when Session has File but user want to change the file

'In this case we have to change the file in session object

ElseIf (photoupload.HasFile) Then

Session("photoupload") = photoupload

' Label1.Text = FileUpload1.FileName;

End If

If (IsPostBack) Then

Return

End If

plant.Items.Add(New ListItem("Kalol Grinding Unit", "3000"))

plant.Items.Add(New ListItem("Surat Grinding Unit", "3100"))

plant.Items.Insert(0, New ListItem("Select ", "0"))

' injurytype.Items.Clear()

injurytype.Items.Add(New ListItem("Near Miss", "Near Miss"))

injurytype.Items.Add(New ListItem("Reportable", "Reportable"))

injurytype.Items.Add(New ListItem("Non Reportable", "Non-Reportable"))

injurytype.Items.Insert(0, New ListItem("Select ", "0"))

'designation.Items.Clear()

designation.Items.Add(New ListItem("Staff", "Staff"))

designation.Items.Add(New ListItem("Worker", "Worker"))

designation.Items.Add(New ListItem("Contractor", "Contractor"))

designation.Items.Add(New ListItem("Visitor", "Visitor"))
