[ronald]

hi,
I have a dataset object which contains 2 datatable (relation). How do i bind this dataset to the radgridview with allowing to insert a new row on both parent and child grid?

So far this is the code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
using System.Collections.ObjectModel;
using System.Data;

namespace WpfApplication8
{
    /// <summary>
    /// Interaction logic for Window3.xaml
    /// </summary>
    public partial class Window3 : Window
    {
        public Window3()
        {
            InitializeComponent();

            this.DataContext = this;

            //RadGridView1.DataMember = CarsSet.Tables["Car"].TableName;
        }


        public DataSet CarsSet
        {
            get
            {
                DataSet carSet = new DataSet();

                DataTable car = new DataTable("Car");
                DataTable comp = new DataTable("Complaint");

                DataColumn col = new DataColumn("AllWheelDrive");
                car.Columns.Add(col);
                col = new DataColumn("Doors");
                car.Columns.Add(col);
                col = new DataColumn("Make");
                car.Columns.Add(col);
                col = new DataColumn("Model");
                car.Columns.Add(col);
                col = new DataColumn("ModelYear");
                car.Columns.Add(col);

                col = new DataColumn("Doors");
                comp.Columns.Add(col);
                col = new DataColumn("DateOfComplaint");
                comp.Columns.Add(col);
                col = new DataColumn("Complaint");
                comp.Columns.Add(col);
                col = new DataColumn("Resolved");
                comp.Columns.Add(col);

                DataRow row = car.NewRow();
                row["Doors"] = "test1";
                row["Make"] = "test2";
                row["Model"] = "test3";
                row["ModelYear"] = "test4";

                car.Rows.Add(row);

                row = comp.NewRow();
                row["Doors"] = "test1";
                row["DateOfComplaint"] = "test4";
                row["Complaint"] = "test2";
                row["Resolved"] = "test3";


                comp.Rows.Add(row);

                carSet.Tables.Add(car);
                carSet.Tables.Add(comp);

                carSet.Relations.Add(new DataRelation("link", carSet.Tables["Car"].Columns["Doors"], carSet.Tables["Complaint"].Columns["Doors"]));
                return carSet;
            }


        }
    }
}

Hi ronald,

I am afraid that in order to achieve this you have to write additional code. Have you considered using another approached based on ViewModel instead? 

I have attached a sample application which demonstrates a scenario similar to yours which uses ViewModels and insertion works on all hierarchy levels. 

Kind regards,
