How would you design this Windows form? - Ronald S. Cook

I need ideas on how to best design a Windows form for my particular
situation.

On a cattle feeding yard there will be between about 300 and 600 pens.  On
my "Pen Feeding Sequence" form, I want the user to be able to setup and
maintain the order in which the pens should be fed (ultimately in the Pen
table is a column named Sequence that gets an interger value).

So on the form...

Sequence     Pen
1            A101
2            A102
3            B245
4            C763


Easy enough.

I suppose I could have a datagrid of Pens ordered by sequence and the user
would click to edit each row and put a number (or blank) for the sequence
number.  But that's the easy way out for me the developer.

I want what would be slick for the user.  Some sort of dragging of a pen to
a number?  I could see that easily if the number of pens would fit on one
form but we're talking hundreds here.

Any thoughts?

Thanks,
Ron
