This is the default behavior of DataGridView already. You don't have to do anything special.

I checked on a DataGridView application I have. I press Enter, the selection goes to next cell. This is the default behavior.

This only when you are not Editing any cell.
If you are editing any cell and wanted to move on next object (Cell/Control) you need to use above function.

create a custom control inherit from gridview
override below two methods. and use this custom gridview instead of datagridview.

VB

Protected Overrides Function ProcessDataGridViewKey(ByVal e As System.Windows.Forms.KeyEventArgs) As Boolean
          Try
              If e.KeyCode = System.Windows.Forms.Keys.Enter Then
                  If MyBase.CurrentCell.ColumnIndex = MyBase.Columns.Count - 1 And MyBase.CurrentCell.RowIndex = MyBase.Rows.Count - 1 Then
                      Dim a As Form
                      a = DirectCast((MyBase.FindForm()), Form)'while last cell of grid it will pass focus to another control on form
                      a.Controls.Find(MyBase.AccessibleDescription, True)(0).Focus()
                  Else
                      MyBase.ProcessTabKey(e.KeyData)
                  End If
                  Return True
              End If
              Return MyBase.ProcessDataGridViewKey(e)
          Catch
          End Try
      End Function


'When edit Particular cell & then press enter
      Protected Overrides Function ProcessDialogKey(ByVal keyData As System.Windows.Forms.Keys) As Boolean
          If keyData = System.Windows.Forms.Keys.Enter Then
              If MyBase.CurrentCell.ColumnIndex = MyBase.Columns.Count - 1 And MyBase.CurrentCell.RowIndex = MyBase.Rows.Count - 1 Then
                  Dim a As Form
                  a = DirectCast((MyBase.FindForm()), Form)
                  a.Controls.Find(MyBase.AccessibleDescription, True)(0).Focus()
              Else
                  MyBase.ProcessTabKey(keyData)
              End If
              Return True
          End If
          Return MyBase.ProcessDialogKey(keyData)
      End Function

Happy Coding!
