I'm in a struggle with the DataGridView: I do have a BindingList of some simple objects that implement INotifyPropertyChanged. The DataGridView's datasource is set to this BindingList. Now I need to add an object to the list by hitting the "+" key. When an object is added, it should appear as a new row and it shall become the current row. As the CurrentRow-property is readonly, I iterate through all rows, check if its bound item is the newly created object, and if it is, I set this row to "Selected = true;"

The problem: although the new object and thereby a new row gets inserted and selected in the DataGridView, it still is not the CurrentRow! It does not become the CurrentRow unless I do a mouse click into this new row.

In this test program you can add new objects (and thereby rows) with the "+" key, and with the "i" key the data-bound object of the CurrentRow is shown in a MessageBox.

How can I make a newly added object become the CurrentObject? Thanks for your help!

Here's the sample:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        BindingList<item> myItems;

        public Form1()
        {
            InitializeComponent();
            myItems = new BindingList<item>();

            for (int i = 1; i <= 10; i++)
            {
                myItems.Add(new item(i));
            }

            dataGridView1.DataSource = myItems;
        }

        public void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Add)
            {
                addItem();
            }
        }

        public void addItem()
        {
            item i = new item(myItems.Count + 1);
            myItems.Add(i);
            foreach (DataGridViewRow dr in dataGridView1.Rows)
            {
                if (dr.DataBoundItem == i)
                {
                    dr.Selected = true;
                }
            }
        }

        private void btAdd_Click(object sender, EventArgs e)
        {
            addItem();
        }

        private void dataGridView1_KeyDown(object sender, KeyEventArgs e)

            {
                addItem();
            }
            if (e.KeyCode == Keys.I)
            {
                MessageBox.Show(((item)dataGridView1.CurrentRow.DataBoundItem).title);
            }
        }
    }

    public class item : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;

        private int _id;
        public int id {
            get
            {
                return _id;
            }
            set
            {
                this.title = "This is item number " + value.ToString();
                _id = value;
                InvokePropertyChanged(new PropertyChangedEventArgs("id"));
            }
        }

        private string _title;
        public string title {
            get
            {
                return _title;
            }
            set
            {
                _title = value;
                InvokePropertyChanged(new PropertyChangedEventArgs("title"));
            }
        }

        public item(int id)
        {
            this.id = id;
        }

        #region Implementation of INotifyPropertyChanged
