ciao a tutti

ottengo quest'errore con quest'istruzione :

protected void ldsCategoryList_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
if (fvProducts.DefaultMode == FormViewMode.Insert)
{
DropDownList DepID = (DropDownList)fvProducts.FindControl("ddlDepartment01");
e.SelectParameters["DepartmentID"] = DepID.SelectedValue;
}
}

Impossibile trovare il controllo 'ddlDepartment01' in ControlParameter 'DepartmentID'.

e sinceramente non capisco perche'????

Qualcuno mi puo aiutare?

ciao e grazie
