dropdownlist in datagrid

[samuelberthelot]

Hi,
I'm having a bad time trying to bind a dropdownlist that is in a
datagrid.

Basically I have two SQL tables:
[Person] {PersonId, PersonName, PersonGroupId}
[PersonGroup] {PersonGroupId, PersonGroupName}

A person can only be in one group.

The grid should show the groups in the first column (just a label of
the PersonGroupName)
The second column should be a dropdownlist and should show the list of
persons per group that are assign to the group of a particular row in
the grid.

I've added my template columns to the datagrid, but now I don't know
how to bind the dropdownlist

can you help ?
