ado_dotnet thread: Extract data from a adapter into a view with a string field

HI
I tried to extract a subset of data from a data adapter into a view. The
selection takes place via a ComboBox (cmbValor) into a string field
(test).
I found a example in a Wrox book: ADO.NET Programmer's Reference on page
817-818 witch looks like that:
dsDataView.RowFilter = "Country Like '" & strCountry & "*'".
In my example it looks like that:
test = cmbValor.Text.ToString
SelPos = New DataView(dsPortfolio.Tables("tabPositionDetail"))
SelPos.RowFilter = "wdValorenNr = '" & test & "'" ==> if it is a string
field it produces always 1 record.
if I use: SelPos.RowFilter = "wdValorenNr = '278848'" ===> if it is a
constant it works, but it isn't what I wont.
Have someone a good example?
Many thanks of helping me.
Regards
Robert

Robert,
No reason that shouldn't work - I suugest you check the actual value of
RowFilter in the debugger. The value you are assigning to test may be
incorrect - you don't need the ToString
i.e. test = cmbValor.Text will suffice.

ASP.NET Distributed Data Applications
This book will inspire you with a range of ideas on how data
can be used to drive Web applications, and how that data can
be most effectively utilized at each level of the design.
Inefficient data use leads to the sort of slow, unresponsive
Web applications that nobody enjoys using. By making good use
of both server and client-side code, we can solve these
problems. This book will arm you with the techniques you need
to build Web applications that fly.
