Scott,
If your ArrayList (userList) only contains that values you need to add and
they're in the order in which you want to add them (ie. firstname,
lastname) to the table row it's pretty easy. You'll have to modify your
approach a little. Try...

I did try a loop similar to what you described (at the suggestion of another
poster). Everything took longer yesterday since I was running it over a DSL
connection (VPN into work), but things took longer with just the property
references than they did with property references and row operations.
Chad suggested the same thing you did about profiling it without the row
additions. I tried it with the built-in tracing stuff, and it looks like
the retrieval of the properties is what is taking up all the time, not the
actual row additions.
It appears that the properties are pre-populated thoug
Good call on the AD reads. The timings are much longer by my running this
over a VPN connection, but taking out the row operations has no effect on
the total runtime (99 seconds with the row operations, 102 seconds without
the row operations).

I know you can bind an array to a DataGrid. I know what classes need to

But are you sure that the UserDirecto
You could create a class such as UserDirectoryView and take your array as a
parameter to the constructor. Additionally, have a UserDirectoryObject[]
field that you update whenever the Filter property is set. If you are

Very interesting idea, Mark.
One thing I'm not sure of is how I would replicate the row filtering
functionality you get automatically with DataView.

I used the tracing functionality built into ASP.NET. The process of
populating the DataTable with the contents of the ArrayList is what is
taking up the majority of the time.

In order for ArrayList sort to work properly, I think I would need to
implement IComparable and a specialized IComparer class. I would also have
to come up with a way to implement row filtering for the array list. Since
this functionality is easy to access via the DataView, once the initial

Scott,
Im not certain how your DirectoryEntry wrapper class UserDirectoryObject
is implemented but I would expect that it reads one property at a time
from the DirectoryEntry object or loads them all or each one on demand
from the UserDirectoryObject object. I would expect that your performance

You could just make your list actually expose the needed interfaces for a
DataTable (derive from IBindingList on the list, IEditableObject on the
items), then you don't need to create a DataTable at all!

I'm writing a user profile tool that manipulates information in an LDAP
server.
Why aren't you binding the ArrayList directly? You can sort it as well,
using the Sort() method.
