Answer 1

I solved part of the problem like this

public void init(object grps, Microsoft.Data.SqlClient.SqlConnection conns)
        {
            var testAssembly = Assembly.LoadFrom(grps.GetType().Assembly.FullName?.Split(",")[0] + ".dll");
            var t = testAssembly.GetType(grps.GetType().FullName);
            datatablew = new ObservableCollection<object>();
            string cluc = "select top 10 kod_rel,uet,rtrim(name) as name from statistika.dbo.statpra";
            var comms = new Microsoft.Data.SqlClient.SqlCommand(cluc, conns);
            var readers = comms.ExecuteReader();
            var counts = readers.FieldCount;
            while (readers.Read() == true)
            {
                var ooo = Activator.CreateInstance(t);
                for (int i = 0; i < counts; i++)
                {
                    var obbjj = readers.GetValue(i);
                    try
                    {
                        var pps = grps.GetType().GetProperty(readers.GetName(i));
                        pps.SetValue(ooo,obbjj,null); 
                    }
                    catch { }
                }
                datatablew.Add(ooo);
            }
            readers.Close();
        }    
it remains to be decided
<DataGridTextColumn Header="kod_rel" Binding="{Binding ????,StringFormat=0;-0;#}"/>
`, how to bind kod_rel which is in ObservableCollection<object> , if I bet ```AutoGenerateColumns="true"``` 
then everything works as it should, but I need to define the columns myself .`
