writeXML from session Dataset

[Michael Persaud]

Hi

I have a page that the user loads and they see a dg poppulated from a
session("DS")

when i run the following i get that the "object refference is not set to
instance of an object"

when i try binding dsXMl to another DG there is no records.

Cant i reuse the session and how do i write the XML file

Thanks


Sub WriteXML()
If ChkVerified.Checked = True Then

Dim StrN, Name As String
Name = Session("myid") + Session("uid")
StrN = "../xml/" & Name & ".xml"

Dim dsXml As New DataSet
objDTdg = Session("DS")
dsXml = objDTdg.DataSet

dsXml.WriteXml(Server.MapPath(StrN))

dsXml.Dispose()

end if
End Sub
