DropDownList does not work inside DetailsView

I have a DetailsView with multiple fields and a DropDownList that should update the sexoAnimal field with Male (M) or Female (F).

I added a ControlParameter to SqlDataSource , the parameter takes the selected value in DropDown .

If I leave DropDownList inside DetailsView , it gives this error:

The 'sexDrop' control in ControlParameter 'sexC' could not be found.

If I take it out of DetailsView (example: below), it updates the Sexo field normally.

What can / should I do to work within DetailsView ?

DropDown Code:

<asp:DropDownList ID="sexoDrop" runat="server">
    <asp:ListItem Value="M">Macho</asp:ListItem>
    <asp:ListItem Value="F">Fêmea</asp:ListItem>
</asp:DropDownList>

Parameter:

<asp:ControlParameter Name="sexoC" ControlID="sexoDrop" PropertyName="SelectedValue" />

As I replied in your other question: How to use DropDownList's SelectedValue value? One way to do this is by getting the DropDownList of the DetailsView and doing the update logic inside the code-behind. I have never used SqlDataSource, but the error that is giving the problem is that the DropDownList is not accessible to the SqlDataSource. Just as in code-behind it is necessary to perform a dvId.FindControl ("sexDrop"), it will be necessary to do the same in SqlDataSource. Now how to do this I do not know, because I have never used this control.
