Use Undo and Redo

​

Undo a Change

1. Press Ctrl+Z (or Cmd+Z on macOS) to undo the most recent change
2. The grid reverts to its previous state and scrolls automatically to show the affected row
3. Repeat to undo additional changes, up to the last 50 actions

​

Redo a Change

1. Press Ctrl+Y (or Ctrl+Shift+Z on macOS) to reapply the most recently undone change
2. The grid restores the change and positions the view on the affected row

​

What Can Be Undone

The undo stack tracks the following types of operations:

​

Undo Cascading Dependent Enum Changes

When you edit a parent enum field that triggers cascading updates to child fields via configured relations, the entire cascade is tracked as a single undo action:

1. Change a parent enum value — child fields update automatically
2. Press Ctrl+Z — both the parent change and all child field updates are reverted together
3. Press Ctrl+Y — the parent change and all cascading updates are reapplied

This applies to both single-row edits and bulk edits across multiple selected rows.

​

Undo Multi-Cell Paste Operations

When you paste values into multiple cells, the entire paste operation is bundled as a single undo action. Pressing Ctrl+Z reverts all pasted cells at once rather than requiring individual cell-by-cell undo.

​

Undo Linked Column and Merged Cell Changes

Undo operations on itemLink, multiItemLink, taskLink, and multiEnum columns automatically restore dependent column values. For merged cells (common in itemLink columns within hierarchical levels), the undo operation applies across all rows in the merged cell range. Multi-enum fields use specialized undo logic that converts between internal IDs and visible values, ensuring the display remains consistent after undo/redo.

​

Undo Task Operations

Task operations support full undo:

• Task addition: Undoing a task addition removes the added task row and restores the grid to the previous position
• Task removal: Undoing a task removal restores the task. For single-task items where task fields were cleared, undo restores all cleared task attributes

​

Limitations

​

Verify Undo/Redo

After making changes:

1. Edit a cell value, then press Ctrl+Z — the original value should reappear
2. Press Ctrl+Y — the edited value should be restored
3. Add a row, then undo — the row should be removed and the grid scrolls to the previous position
4. Edit a parent enum with cascading dependents, then undo — all cascading child fields should also revert

You should now see undo and redo working consistently for cell edits, row operations, paste actions, and cascading enum changes.
