    Maybe this isn't proper, but easy trick and same result........ lot less code......I was just playing around and though outside the box, just set

    I hide mine until they click cell, or you can show First I declared :

    DateTimePicker1.Visible = False
    

    when you click in cell, run this code...

        DateTimePicker1.Visible = True
        ActiveControl = DateTimePicker1
    

    Then below

     Public Sub DateTimePicker1_ValueChanged(sender As System.Object, e As System.EventArgs) Handles DateTimePicker1.ValueChanged
    
    
    
        requestDGV.Rows(0).Cells("requestTimeOff").Value = (DateTimePicker1.Value)
        DateTimePicker1.Visible = False
        DateTimePicker1.Enabled = False
    
    End Sub
    

    Super Basic , and i have it sitting directly in the box, doesn't look out of place

    Or super easy mode.......I just like to hide mine till column click

    Public Sub DateTimePicker1_ValueChanged(sender As System.Object, e As System.EventArgs) Handles DateTimePicker1.ValueChanged
    
    
        requestDGV.Rows(0).Cells("requestTimeOff").Value = (DateTimePicker1.Value)
    
    End Sub
    

    You really just need that one line.....data will be in the grid, just a lot less code.....

    Ok... Using some of @rajat and @Aaron examples, i made one that pops up on the DateTimePicker cell. Thanks everyone.

    Private Sub DataGridView1_CellClick(sender As Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellClick
    
        If e.ColumnIndex = 8 Then 'CHECK IF IT IS THE RIGHT COLUMN
    
            'SET SIZE AND LOCATION
            Dim rect = DataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, True)
            DateTimePicker1.Size = New Size(rect.Width, rect.Height)
            DateTimePicker1.Location = New Point(rect.X + 10, rect.Y + 76) 'USE YOU OFFSET HERE
    
            DateTimePicker1.Visible = True
            ActiveControl = DateTimePicker1
    
        End If
    
    End Sub
    
    
    Private Sub DateTimePicker1_ValueChanged(sender As Object, e As EventArgs) Handles DateTimePicker1.ValueChanged
    
        If DataGridView1.RowCount > 0 Then 'JUST TO AVOID FORM LOAD CRASH
    
            DataGridView1.CurrentCell.Value = DateTimePicker1.Value.ToShortDateString
            DateTimePicker1.Visible = False
    
        End If

    One strategy would be:

    1. to paint a DateTimePicker on top of the selected cell when it receives focus
    2. hydrate the dtp with the cell's values
    3. when the dtp's value changes, mirror it back into the cell's value
    4. and hide the dtp when the cell loses focus

    Here's a way to handle grid events with the laid out strategy:

    private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
    {
        // determine if click was on our date column
        if (dataGridView1.Columns[e.ColumnIndex].DataPropertyName == nameof(User.BirthDate))
        {
            // initialize DateTimePicker
            dtp = new DateTimePicker();
            dtp.Format = DateTimePickerFormat.Short;
            dtp.Visible = true;
            dtp.Value = DateTime.Parse(dataGridView1.CurrentCell.Value.ToString());
    
            // set size and location
            var rect = dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);
            dtp.Size = new Size(rect.Width, rect.Height);
            dtp.Location = new Point(rect.X, rect.Y);
    
            // attach events
            dtp.CloseUp += new EventHandler(dtp_CloseUp);
            dtp.TextChanged += new EventHandler(dtp_OnTextChange);
    
            dataGridView1.Controls.Add(dtp);
        }
    }
    
    // on text change of dtp, assign back to cell
    private void dtp_OnTextChange(object sender, EventArgs e)
    {
        dataGridView1.CurrentCell.Value = dtp.Text.ToString();
    }
    
    // on close of cell, hide dtp
    void dtp_CloseUp(object sender, EventArgs e)
    {
        dtp.Visible = false;
    }
    

    And Here's a basic setup for a form that has a DataGridView added to it

    private void Form1_Load(object sender, EventArgs e)
    {
        // add columns
        var nameCol = new DataGridViewTextBoxColumn(){DataPropertyName = nameof(User.Name),HeaderText = "Name"};
        var dateCol = new DataGridViewTextBoxColumn(){DataPropertyName = nameof(User.BirthDate),HeaderText = "Birthday"};
        dataGridView1.Columns.AddRange(nameCol, dateCol);
    
        // add data source
        var users = new List<User>()
        {
            new User() {Name = "Briana", BirthDate = new DateTime(2019,10,10)},
            new User() {Name = "Grace", BirthDate = new DateTime(2018,1,18)}
        };
        dataGridView1.DataSource = users;
    }
    
    private  DateTimePicker dtp { get; set; }
    
    private class User
    {
        public string Name { get; set; }
        public DateTime BirthDate { get; set; }
    }
    

    Note: This approach does not currently handle keyboard events when the dtp has focus and also does not handle resizing or repainting if the form moves around

    To solve some entry issues when using the DateTimePicker in a DataGridView you will want to add the following to the Microsoft Sample referenced above. It took quite a while to search out the problems with the valuechanged event not firing as expected. The fix came from here (stackoverflow) and translated to C# below. It seemed appropriate to add this information here as I keep finding this forum post when searching on DataGridView and DateTimePicker.

        protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
        {
    
            switch (keyData & Keys.KeyCode)
            {
                case Keys.Enter:
                case Keys.Tab:
                    this.dataGridView.Focus();
                    break; 
            }
    
            return base.ProcessCmdKey(ref msg, keyData);
    
        }

    You haven't missed any built-in option, but it is possible to subclass both the DataGridViewColumn and DataGridViewCell classes to host any control of your choosing.

    This article on MSDN explains the process in more detail, and even includes some sample code:
    How to: Host Controls in Windows Forms DataGridView Cells

    You can also find a complete sample on Code Project: Generic DataGridView V2.0

    I think the CloseUp event on DateTimePicker is more appropriate because the changed value is triggering on any change while CloseUp only triggers when the entire date is selected
