Thank you Scott, yes I need the position?  

I need the position because I take the tripID value from this secondary data
source called Trips.  I use that value to set the /dfs:queryFields/d:tripID
value in my Main data source.  

So when a user for example clicks on the >> button.  In order to display the
next record, I need to code to get the TripID value from the next record from
the Trips secondary data source and then change the /dfs:queryFields/q:tripID
in the Main Data Connection to that value and then re run the Main query to
get that records info.

Maybe this will shed more light.  

Views:
Main
TripDetails

Data Sources
Main (Default) (This is the database connection to SQL the form was built
off of)
Trips (Secondary) This populates the Repeating table on the main View from a
table in SQL called Trips.

The repeating table in Main does have a button that when clicked kicks off a
rule named Query.

Query has 3 actions:
1) Sets field value of /dfs:Main/dfs:queryFields/q:Trips/@TripID to
xdXDocument:GetDOM("Trips")/dfs:myFields/dfs:dataFields/d:Trips/@TripID
2)Query using a Data connection: Main
3) Switch to View: TripDetails

All this works fine.  Now I'm trying to add functionality to where if a user
wants to go to the next, previous, first or Last record they click on a
corresponding button such as |< << >> >|

So say they click on the next button in the tripDetails view, I need to
access the TripsDetail Data Connection which was kicked off by the Main view.
I need to then get the TripID value from the next record in the xml "Data
Set" so I can then set the TripID of the Main Query TripID field and re run
the query.

So that's why I need the Row position.  When a user first clicks on a record
in the main view to get the details of the selection, I'm going to populate a
global variable with the row position.  When they click next, I will then
increment this variable by one.  Then try to figure out the VB.Net code
equivalent that will give me the same functionality of this XPath statement
which works when set in a rule.

xdXDocument:GetDOM("Trips")/dfs:myFields/dfs:dataFields/d:Trips[position() =
2]/@TripID

What I'm trying to do is come up with the value of 2, 3, 4 or whatever the
next or previous position value may be when clicked.

Hello Greg,

This is a form that is bound to a SQL database.  Is there a way to create a
secondary data source for me to write and retrieve info to with a form such
as this?  I did look at the example you referenced me to in another post and
if I weren't using a form bound to SQL I see what you are saying.  But in my
case the Add button to create a data source is grayed out.  Also, if I try to
create a secondary data source, it's just to read info and it has to be a xml
file, web service, database etc.

Is there some other way to create a secondary data source with a database
form that I'm missing?

Thanks.

P.S.  You are correct Scott, these are 4 buttons in a separate view from
where the data source I'm connecting to is first populated.
