Dataview into new table ???

Hi,

I've come a stage that I'm feeling an absolute idiot.
Struggling with this issue for days and can't find a suitable answer.

Have this dataset which 'amount' value can be updated. Need to send all
records with 'amount > 0' to a webservice as a Datatable. (Ignorant as I
might be) I Dim a new DataView (rowfilter 'amount > 0') and copy this into a
new datatable:
dv = New DataView(ds.Tables("Items"), _
"amount > 0", _
"barcode", _
DataViewRowState.CurrentRows)

Dim dt As New DataTable("Result")
dt = dv.Table.Copy
sendDS.Tables.Add(dt)

However, sending this datatable (dt) to a webservice will send the entire
source dataset (= huge)

What am I doing wrong ...
Is there a more suitable way of achieving this!?

Thanks in advance.

Hi, Sjaakie Helderhorst,

Maybe you can send a new DataSet containing only the DataTable in question.

Hope this helps

Hi, Sjaakie

You might try the following

sendDS = ds.Clone(
Dim copyRows() As DataRow = ds.Tables("Items").Select("amount > 0"
Dim dt As DataTable = sendDS.Tables("Items"
Dim copyRow As DataRo
For Each copyRow In copyRow
dt.ImportRow(copyRow
Nex

Hope this will help
