Hi laghaterohan,

First of all, why do you need a DropDownList in the Item Template? In the ItemTemplate you only show the data, not modify it, so I don't see a reason for include the DDL in the ItemTemplate.

To create a DropDownList in the GridView you can do like this:

<asp:GridView ID="GridView2" runat="server" DataSourceID="DataSource1" DataKeyNames="ID"
        SelectedValue='<%#Bind("Name") %>'>
            <asp:TemplateField HeaderText="Id">
                    <asp:DropDownList ID="MyDDL" DataSourceID="DDLDataSource" DataTextField="CountryName" DataValueField="CountryID"
        <asp:SqlDataSource ID="DDLDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:server %>"
        SelectCommand="SELECT CountryID, CountryName FROM CountriesTable ORDER BY CountryName">

You can Bind the DDL using a SqlDataSource, for example, or you can bind in the code behind. I recommend you to bind in the code behind; it's a little bit more work, but it's easier to debug.
I hope this helps.

If you have any other questions, just ask =)
