I'm really thankful. It works, but I'm really sorry but now i have this:

Table A:
ID Resource IDgroup
1 Callcenter 2

Table B:
IDgroup Description
1 Human Resources
2 Networking


And with your help, when I hit edit, it displays the content with the
dropdown list as it should be and I'm able to update it, but after that it
displays back the content of table A. Is there a way that in normal mode i
can display the grid like this:

Gridview:
ID Resource IDgroup
1 Callcenter Networking

Thanks again.

it's a matter of your request, if you said "IDgroup" it shows "2"
because this is the value from IDgroup field. To show Description
value from another table you need to join that table.

For example, look at the article I sent you. There is a request like

<asp:SqlDataSource ID="..." Runat="server"
SelectCommand="SELECT ...."
ConnectionString="<%$ ConnectionStrings:NWConnectionString %>">

You would need to change that SelectCommand as

SelectCommand="SELECT a.ID, a.Resource, a.IDGroup, b.DESCRIPTION
FROM tableA a, TABLEB b
WHERE a.IDGroup=b.IDGroup"
