HI all,
Need to populate fields using VB (code behind).

field1:
ID bound to a datasource called datas1

field2:
ID bound to datasource2 called datas2

field3:
Yr bound to datasource2 called datas2

The field2(same as field1) and 3 are populated once field1 has been found on
XXX table.

I know I can use rules and actions based on value changed of field1 to
populate field2 but I also have some other tables that are queried based on
the values of fields2 and field3. Basically, I am creating schedules for
students using the student's ID and School year.

How can I read the values of field1 from vb.net and how can I set the values
for field2 and field3?
I can read some of the values using the follwing:

Dim root, user2 As System.Xml.XPath.XPathNavigator
           root = Me.MainDataSource.CreateNavigator
           user2 =
root.SelectSingleNode("/dfs:myFields/dfs:queryFields/tns:GetProfile/tns:Studentid", Me.NamespaceManager)
           'user =
root.SelectSingleNode("/dfs:myFields/dfs:queryFields/tns:Getsyears/tns:studentid", Me.NamespaceManager)
MessageBox.Show(user2.ToString)

I think my problem is in how to read the nodes(query fields) using different
datasources.
