Hi Miguel,
Here's a way to add a dropdownlistbox to a grid and select the corresponding
item.
Filling the dropdown could be much more efficient, but this gives you the
idea.
Let us know if this helps?

Hello,
I have two questions concerning Asp:DropDownList
1. How to fill a DropDownList from runtime and set its default item?
2. How do use a DropDownList in each datagrid record?
All dropdownlist should be filled with the values in field NAME from the
same dataset used in the datagrid.
The default value of each dropdownlist should be the value of NAME by
that record.
Thanks,
Miguel
