I'm currently building a usercontrol with a lot of little checkboxes.

By clicking on them you create a seqence of ones and zeros. These are stored in a database.

The problem is that someone else has to put some of these one-zero seqences in an other database. I would like to do this by showing to controls where the one-zero seqence is copied from one usercontrol to the other.

My problem is where do I store the temporarly data and how do I know above with other control the user drops the data. Do I use the form for this? Or is everything done from within the control?

Please help me, I need it badly.
