In a DataSet, the collection of all parent DataRelation objects for the data set is returned by the GetParentRows method.

The DataTable also contains a collection of DataRelation objects, returned by the ParentRelations property.

The following example uses the GetParentRow to print a value from each parent row of each DataRow in a DataTable.

private void GetParentRowForTable(
    DataTable thisTable, string relation)
{
    if(thisTable ==null){return;}
    // For each row in the table, print column 1 
    // of the parent DataRow.
    DataRow parentRow;
    foreach(DataRow row in thisTable.Rows)
    {
        parentRow = row.GetParentRow(relation);
        Console.Write("\table child row: " + row[1]);
        Console.Write("\table parent row: " + parentRow[1]+ "\n");
    }
}
 
private void CallGetParentRowForTable()
{
    // An example of calling the function.
    DataTable thisTable = DataSet1.Tables["Products"];
    DataRelation relation = thisTable.ParentRelations[0];
    GetParentRowForTable(thisTable, relation.RelationName);
}
