I created a dataset at design time, filled it with tables, and the tables
with columns. One of the columns in each table contains an expression (I
just concatenated 3-4 columns from the same table). But I get nothing when I
read the info in that cell. It's not null, just returns an empty string -
this is after string values have been added to the columns used for the
expression.

What am I doing wrong?

Hard to say without seeing any of the code you are using. :-)

Can you post a 10 to 20 line sample that demonstrates the problem, as I am
not able to recreate it.

Thanks
Jay
 
That's just it - I'm not doing it in code, I'm creating the expression at
design time.

Ken,
Wouldn't you agree: Without seeing the expression that you are creating at
design time, no one can really help you?

In other words, what is the expression that you are typing into the
designer? Or can you attach a single table, 5 field table from the designer
that demonstrates the problem, the .xsd itself. Also include how you are
adding the rows to the DataTable.

If you would prefer not to post the .xsd, you can email it to me, my address
is not spam proof. NOTE to lurkers I only look at code from individuals I
ask to send me code, thanks for understanding.

Hope this helps
Jay
