A cell can't be edited

Pressing F2 or Enter, typing, or double-clicking doesn't open an editor in a WklTreeList cell, or EditCell raises wkeInvalidValue.

All versions of WklTreeList.

One of the following applies:

• AllowEditing is False.
• The column is ReadOnly.
• The node is a group node (GroupFields); groups don't represent records.
• BeforeCellEdit set Cancel = True.

If the editor opens but the value doesn't stick, the save failed; see Changes in the tree aren't saved.

1. Check AllowEditing (property sheet, Other tab) and the column's Read-only setting (designer's Columns page).
2. Check BeforeCellEdit in the form module.
3. In grouped lists, edit the record rows (leaf nodes); group rows can't be edited.
