title: Edit a TextBox cell in DataGridView as if it were a normal TextBox (no jumping on pressing arrows)
body: <p>I have "multiline" (wordwrapping) textbox columns in a DataGridView. It would be great to be able to edit them as normal TextBoxes, that is, <strong>when I press down arrow, I want the caret to go down one line within the textbox, I don't want it to jump to the next row, as it normally does</strong>. Likewise, <strong>I want that pressing enter creates a new line within the textbox cell, but it instead finishes editing</strong>.</p>
  
  <p>Otherwise said: I want to override normal behaviour of some keypresses (or keydowns), so that user can edit a textbox cell as if it were a normal textbox, and navigate inside it with arrows and create new lines with enter.</p>
  
  <p>I tried manipulating keydown events in DataGridView, but it didn't work.</p>
  
  <p>Thank you for any ideas or comments.</p>
