FW: ADO.NET - Filtering DataSet

Vince P 27 January 2004 16:52:50
 Anyone know a good ADO.NET list?

I have a (strongly typed) populated DataSet. Is there any convenient method
or class to get the Distinct values of all the data in a certain column
without having to back to the database?

 Try to CLR listserv.

Select on DataTable may be what you want.

 We did it in client side ourselves (as long as the dataset does not contain
more rows)

DataTable dtConstraint = dtSource.Clone();
dtConstraint.Constr­aints.Add(<columns>)­

foreach(Datarow row in dtSource.Rows)
{
Try
{
dtConstraint.Rows.A­dd(row.ItemArray)
} catch (ConstraintExceptio­n)
{
// do nothing.
}
}
