I am working on a form with a grid or listview which will show data from a related table as a lookup and I would like to show a descritive fields instead of the Foreing Key field value, how can I do this?

In the picture attached, the FK_Appliances in the Grid or Appliance in the List View are the ones I want to show the descriptive field instead of the FK value.

Also, since I am learning SF, I found that the creation of a ListView is a bit difficult than using a GridView for read only data, is there a way to show the grid with empty columns like in the ListView in order to cover the gray area of the grid?

Thanks!

After a second thought, I decided to try Tim's suggestion to create a Custom Property and after reading Tim's great sample and with the SF help file, I could not believe how easy it was to have 2 Custom Field Properties to handle this situation and not have to add a single line of code at the form level, which keep the things simple.

For the sake of new SF users, here is the code for one of my Custom Field Properties:

Once again, big thanks to Tim and Trent for the lecture on how to accomplish this task.
