FileUpload control and formView Inserting Event

[RosH]

Dear All,

Please find below an Inserting Event code expected to trigger just
before the insert event of a FormView control. Everything works just
fine but the event throws an exception that the parameter Filename is
null. As you can see in the code that I have tried to update the
UploadedFileNam e textbox which is bound to the Filename column of the
database connection. During execution of the command, it is not found
to update the UploadedFileNam e textbox's text property even though I
have explicitly declared the textbox variable "MyUploadedFile Name".
Please help me out.

Protected Sub FormView1_ItemI nserting(ByVal sender As Object, ByVal e
As System.Web.UI.W ebControls.Form ViewInsertEvent Args) Handles
FormView1.ItemI nserting

Dim MyUploadedFileN ame As TextBox =
FormView1.FindC ontrol("Uploade dFileName")

Dim path As String = Server.MapPath( "~/UploadedImages/")
Dim fileOK As Boolean = False
If FileUpload1.Has File Then
Dim fileExtension As String
fileExtension = System.IO.Path. _
GetExtension(Fi leUpload1.FileN ame).ToLower()
Dim allowedExtensio ns As String() = _
{".jpg", ".jpeg", ".png", ".gif"}
For i As Integer = 0 To allowedExtensio ns.Length - 1
If fileExtension = allowedExtensio ns(i) Then
fileOK = True
End If
Next
If fileOK Then
Try
FileUpload1.Pos tedFile.SaveAs( path & _
FileUpload1.Fil eName)
MyUploadedFileN ame.Text =
FileUpload1.Fil eName.ToString( )
Catch ex As Exception
Label1.Text = "File could not be uploaded."
End Try
Else
Label1.Text = "Cannot accept files of this type."
End If
End If
End If
End Sub
