I think this will be a good one for anyone who fancies themselves a wiz
with manipulating data structure in vb.net. Imagine a Dictionary
collection of Object "A". One of the properties of Object "A" is
dictionaty collection of Object "B". Can I sort Object "A" using one of
the properties within the collection of Objects "B"?

Using the data structure below, a report has many lines, each line has
many items, each item is made up of a current value and previous value.
I want to sort the lines of the report using the current value of one
of the items.

Does this make any sense? Can it be done. I know there are people out
there who live to figure out stuff like this (bless you... we need more
of you).

Thanks... Sherry

Hi,

I am not sure I have fully understood the problem...

At first sight, it would seem natural to define A as a SortedList
(where items are dictionary entries) and define a Comparer
which uses the properties of objects B which you wish to
use for ranking purposes...

One of the properties of Object "A" is
