Use Parameters according to MSDN MSDN[^]

But it's wrong: there is no SqlDataAdapter.Parameters. Use this:

using (SqlConnection connection_v = new SqlConnection(strCon))
    {
    SqlDataAdapter fgrid = new SqlDataAdapter("Select Date,Item_Code,Quantity,ID From Finished_Goods_Stock Where Date = @f_date,Item_Code = @f_code", connection_v);
    fgrid.SelectCommand.Parameters.AddWithValue("@f_date", DateTime.Now);
    ...
    }
