- "startEdit" (default) - switches the cell to the editing state
-
enterKeyDirection
Specifies the direction in which to move focus when a user presses Enter:- "row"
- "column"
- "none" (default)
-
editOnKeyPress
Specifies whether to start entering a new cell value on a key press.
In this demo, you can use the controls under the TreeList to change any of these properties.
