OverWriting dataTable Obj on each Rows.Add

[rikb53]

somehow im not managing whats being added to the data table and its overwriting each time i add some thing. if the DataTable is created at runtime, each postback shouldn't destroy it or so i thought.
this works great - its just overwriting each click of the first grid. i left that code out of here. im adding values to the datacolumns, then to the datarow and then add the datarow to the dataTable. but, ill be darned if it's not overwriting it. i'm missing something simple here i know.
any help is appreciated

Public Vars::
Public dt2 As New DataTable
Public aRow As DataRow
Public dcCol1 As New DataColumn("Name", GetType(String))
Public dcCol2 As New DataColumn("Dept", GetType(String))
Public dcCol3 As New DataColumn("Email", GetType(String))

i pass e.item.cells(0).text to the sub below based on what's clicked in the first datagrid::::


Private Sub addToGrid(ByVal myName As String, ByVal myemail As String, ByVal myDept As String)

Try
aRow = dt2.NewRow
dt2.Columns.Add(dcCol1)
dt2.Columns.Add(dcCol2)
dt2.Columns.Add(dcCol3)
aRow(dcCol1) = myName
aRow(dcCol2) = myDept
aRow(dcCol3) = myemail

dt2.Rows.Add(aRow)
For Each aRow In dt2.Rows
DG2.DataSource = dt2.DefaultView
DG2.DataBind()
Next

Catch ex As Exception
Response.Write(ex.Message)
End Try

End Sub

Every time an asp.net event occurs, the Page_Load event i triggered.

Try using

If Not Page.isPostBack Then
'execute your function call
End If

will do. yeah, i finally gave up on it and made everything table driven using temp tables. works fine, but i was hoping to do this all Using Collections in memory.
i also thought, of recycling the contents of the datatable along with the new row that's being added, but went the table-driven way before i got to that point
thanks for the help
