I'm trying to use a GridView to display a list of components in ASP.NET. I'm trying to make it editable at the same time. One of the columns is a string that should be selected out of a list when the user edits the row.

So I've tried the following:

1. Convert the BoundField row to an ItemTemplate
2. Add a dropbox to the template window in the gridview
3. bound the selecteditem to the string

At this point, I get an error because the list items haven't been set up in the dropbox. So I guess the two things I'm wondering are:

1. How do I assign the items in the dropbox to a dynamically created list of options?
2. How do I make the dropbox only appear when the row is being edited?
