WinForms DateTimePicker to Selected Cell from DataGridView-CodePudding

I am new to WinForms and am trying to make an application that will hold certain data in a DataGridView Style.
Now I've managed to create the app where if clicked on a cell the TextBoxes and the ComboBox get populated with data from the GridView, but I am now struggling to get the DateTimePicker to do the same...
Bellow you will see the code I am using to call the data back into the text and combo boxes, but I am missing the proper call for the DateTimePicker and I don't know how to call it properly

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    index = e.RowIndex;
    DataGridViewRow row = dataGridView1.Rows[index];
    textBox1.Text = row.Cells[0].Value.ToString();
    dateTimePicker1.Value = row.Cells[1].Value.ToString();
    comboBox1.Text = row.Cells[2].Value.ToString();
    textBox2.Text = row.Cells[3].Value.ToString();
}

I am aware I can't convert type string to System.DateTime, but I don't know how I can do that...

Thank you in advance.

The type of

If you'd like to try this approach, make a class to represent a Row in the view.

class Record
{
    public string Description { get; set; } = $"Item {autoName  }";
    public DateTime Date { get; set; } = DateTime.Now;
    public CBValues Value { get; set; } = CBValues.Apple;

    static char autoName = 'A';
}

enum CBValues
{
    Apple,
    Orange,
    Banana,
}

Next make a BindingList<Record> of them...

BindingList<Record> Records = new BindingList<Record>();

and set it as the DataSource of your DataGridView in this initialization method which also installs the custom columns (the CalendarColumn class is copied from this Microsoft sample).

private void InitializeDataGridView()
{
    dataGridView1.AllowUserToAddRows = false;

    // Bind the list of records to the DataGridView
    dataGridView1.DataSource = Records;

    // Add one or more records to autogenerate the Columns
    for (int i = 0; i < 3; i  ) Records.Add(new Record());

    // Swap autogenerated column for CalendarColumn.
    dataGridView1.Columns.Remove(dataGridView1.Columns[nameof(Record.Date)]);
    dataGridView1.Columns.Add(
        // This class is copied from Microsoft example.
        new CalendarColumn
        {
            Name = nameof(Record.Date),
            DataPropertyName = nameof(Record.Date),
        });

    // Swap autogenerated column so DataGridViewComboboxColumn.
    dataGridView1.Columns.Remove(dataGridView1.Columns[nameof(Record.Value)]);
    dataGridView1.Columns.Add(
        new DataGridViewComboBoxColumn
        {
            Name = nameof(Record.Value),
            DataPropertyName = nameof(Record.Value),
            DataSource = Enum.GetValues(typeof(CBValues)),
        });

    // Format columns
    dataGridView1.Columns[nameof(Record.Description)].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
    dataGridView1.Columns[nameof(Record.Date)].Width = 150;
}
