    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
    UploadedFileName textbox which is bound to the Filename column of the
    database connection. During execution of the command, it is not found
    to update the UploadedFileName textbox's text property even though I
    have explicitly declared the textbox variable "MyUploadedFileName".
    Please help me out.

    Protected Sub FormView1_ItemInserting(ByVal sender As Object, ByVal e
    As System.Web.UI.WebControls.FormViewInsertEventArgs) Handles

    Dim MyUploadedFileName As TextBox =

    Dim path As String = Server.MapPath("~/UploadedImages/")
    Dim fileOK As Boolean = False
    If FileUpload1.HasFile Then
    Dim fileExtension As String
    fileExtension = System.IO.Path. _
    Dim allowedExtensions As String() = _
    {".jpg", ".jpeg", ".png", ".gif"}
    For i As Integer = 0 To allowedExtensions.Length - 1
    If fileExtension = allowedExtensions(i) Then
    fileOK = True
    End If
    If fileOK Then
    FileUpload1.PostedFile.SaveAs(path & _
    MyUploadedFileName.Text =
    Catch ex As Exception
    Label1.Text = "File could not be uploaded."
    End Try
    Label1.Text = "Cannot accept files of this type."
    End If
    End If
    End If
    End Sub
