I need a form which allows users to build up an order.

On the form will be a datagrid showing stock "gridStock".

The users need to be able to choose items from the "gridStock" and add them
to another datagrid "gridOrder" which will act as a source for a crystal
report.

I know this is a very general question but I have no idea how to approach
it. I am new to VB.Net having previously programmed this sort of thing with
ease in Access but in .Net this seems like a bit of a nightmare.
Lets just say my boss expects me to develop and learn .NET from scratch and
meet deadlines at the same time. What a way to make a living!

Can anyone point me in the right direction?

How should I approach such a problem?
