Working with ViewState

[Memnoch1207]

I am saving uploadPaths into the ViewState by doing this

Private Sub btnUpload_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpload.Click
    i = 1 'declared as global variable
    uploadCount = 1 'declared as global variable
 
    ViewState("UploadPath" & i) = attachmentFile.PostedFile.FileName
 
    'rest of code
 
    uploadCount = +1
    i += 1
End Sub

When I view the data in ViewState I can see the first uploaded value, but it doesn't save any additional uploads into ViewState.

And when I try to read the values from ViewState

For i = 1 To uploadCount
    Response.Write("UploadPath: " & ViewState("UploadPath" & i) & "<br>")
Next

It isn't returning any values....Why is this...Am I missing something???
