Try this. May help. good way to find the item in the list and if found set it selected.

SQL

if(DropDownList1.Items.FindByText(dr["FiledName"].ToString())!=null)
{
                DropDownList1.Items.FindByText(dr["FiledName"].ToString()).Selected = true;

which error you are still getting ...?
if you have duplicate field names than try to set selected index by its value like this

DropDownList1.SelectedIndex = DropDownList1.Items.IndexOf(DropDownList1.Items.FindByValue(dr["FiledName"].ToString()));

DropDownList1.ClearSelection();
DropDownList1.Items.FindByText(dr["FiledName"].ToString()).Selected = true;
