You can use Ctrl + Z to undo an action in the control. You can then use Ctrl + Y to redo the action you canceled.
You can undo the following types of actions:
- Editing text
- Autofit when double-clicking
- Resizing headers
- Dragging columns or rows with the mouse
- Expanding or collapsing groups with the group button
- Editing the sheet tab name by double-clicking on the tab strip
- Using Ctrl + V to paste
- Using the DoCommand to create a row or column group
The following actions do not respond to Ctrl + Z:
- Sorting or filtering with the drop-down button
- Selecting a range
- Navigating to a specific cell
- Scrolling
- Dragging a split box to create new viewports
- Resizing the tab strip resize box
- Double-clicking the new tab option on the tab strip
You can prevent or allow the undo action in code with the CanUserUndo property.
