Answer 1

For the 1 part of your question:

CustomerName is probably null, since you have no input with that name on your partial. You only have @Html.DropDownList("CustomerID", "Select") which will pass in your CustomerID only, not the CustomerName . But I don't think that is a huge problem, I suppose you'll store the ID in the database anyway.

If you need the name, you can probably simply get it from the database based on the CustomerID value.

The second part is not completely clear for me, what should be the condition which makes a different between the two windows to show?
