Forms Data Controls :: How To Add Lookup Table Values To A DropDownList And Bind To A FKValue In The Grid

I have a GridView control that has a SQLDataSource.

The GridView provides me with a list of musical artists (from the tblArtists)

In the Grid, I have a field, FKGenreID, that is a Foreign Key value for music Genres.

(An example of the data in that field would be "7", which upon lookup would mean Classical in the
tblGenreList table.)

What I'd like to do is add a DropDownList control that looks up the tblGenreList table and populates the DropDownList with the ID and Description from the tblGenreList Lookup table.

Now the tricky part is that if the GridView field (FKGenreID) has a value, then I'd like the corresponding Genre Description to be displayed in the DropDownList

Alternately, if there is no value for FKGenreID in the GridView, then I'd like the DropDownList to show that nothing was selected, but have the list of Genres available.

Most importantly here, when the user makes a selection, I'd like the GenreID (from the DropDownList) to be entered into the FKGenreID field in the GridView field.

My thought is that a gridview record may or may not have a value in the FKGenreID field. Either way, the DropDownList is bound to that field. The DropDownList would display a list ofGenre Descriptions for the user to select from. Upon selection, the GenreID column of the DropDownList becomes the value in for the FKGenreID field in the GridView.

Is this possible?

In case it matters, I'm using ASP.NET 4, Visual Studio 2010, and coding in VB
