You need to be able to retrieve data from DataSet object
that has four DataTable objects. There are currently
UniqueConstraint and ForeignKeyConstraint Object on the
DataTable objects to enforce the data rules. You find that
you can retrieve the data from the individual DataTable
objects, but you are not able to retrieve the data from the
combination of DataTable objects in a Parent/Child manner.
What should you do to able to retrieve the data in a
Parent/Child manner?
a) Set the EnforceParentChild parameter of the DataSet to True.
b) Set the EnforceRelation parameter of the Relations
collection to True.
c) Add DataRelation objects to the Relations Collection to
make the DataSet present the data in Parent/Child manner.
d) Add a primary key and a foreign key to each of the
DataTable objects that should present the data in a
Parent/Child manner.

Hello,
Using Visual Studio 2005 (VB) I am working to create a Web
Site implementing the following:
Within a gridView I have placed a dropdownlist control with
a DataSourceID="SDSLkupList".
SDSLkupList is a sqlDataSource used to store a lookup list
for dropdownlist
translation from ID to text. SDSLkupList contains the
translation text and other fields
related to the dropdown selection ID. (Thought it would be
efficient to get everything
at the same time.)
I would like to provide the user the ability to select from
the dropdownlist and, based on the
selection, use labels to list related columns stored on the
SDSLkupList in separate gridView
columns.
I have read that SqlDataSources are not meant to be used
for individual controls. Since
SDSLkupList contains all related information, is there a
way to do a find using the
dropdownlist selectedValue? (I was not able to discover
one.)
Otherwise, what should I use? It would need to set the
labels on the gridView DataRowBound
event as well as the SelectedIndexChanged events.
Has anyone done this?
Any help would be appreciated.
Thanks in Advance.
