Ok for that u will have to write code on dropdown selected index changing and
make its autopostback property true;
and write code as
SqlCommand cmd = new SqlCommand("select * from tableme where item=@item ", con);
con.Open();
cmd.Parameters.AddWithValue("@item ", dropdown.selectedvalue );

SqlDataReader dtr = cmd.ExecuteReader();
if (dtr.Read())
{
Label1.Text=dtr["Rate"].Tostring();
dtr.Close();
con.Close();

}
else
{

Label1.Text = "No Price is there";
dtr.Close();
con.Close();

}
