System.NullReferenceException: Object reference not set to an inst

I'm loading an Array below but getting the error "Object reference not set t
o
an instance saying 'ItemNumber = CType(Args.Item.FindControl("ItemNumber"),
TextBox).Text' is the error line.
I DON'T KNOW WHAT I'M DOING WRONG I USED ASP.NETWebMatrix and its working
well!!
Any help!!
I have declared ItemNumber as u can see below
" :-
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
' Load array ItemNumberList with item numbers
'Dim ItemNumberList = New ArrayList
Dim ItemNumberList = New ArrayList
DBConnection = New
SqlConnection(" server=(local);database=Northwind;integr
ated security=true;")
DBConnection.Open()
SQLString = "SELECT ItemNumber FROM products1 ORDER BY ItemNumber"
DBCommand = New SqlCommand(SQLString, DBConnection)
DBReader = DBCommand.ExecuteReader()
While DBReader.Read()
ItemNumberList.Add(DBReader("ItemNumber"))
End While
DBReader.Close()
DBConnection.Close()
ItemNumberList.TrimToSize()
End Sub
Dim ItemNumber As String
ItemNumber = CType(Args.Item.FindControl("ItemNumber"), TextBox).TextHi,
The code in Page_Load() has nothing to do with these two lines:
Dim ItemNumber As String
ItemNumber = CType(Args.Item.FindControl("ItemNumber"), TextBox).Text
What is Args? It looks like you already know the control name. Why not?:
ItemNumber = ItemNumber.Text
That should work fine. Are the two lines of code above in another
subroutine? The code you posted doesn't seem relevant in any way to each
other. Please post a better sample of what you are trying to do. Thanks
and Good luck! Ken.
