Remarks

In the read-only mode, cell editors can be invoked. However, an end-user can only select and copy an editor’s content. The ReadOnly property enables the read-only status for the current TreeList.

To prevent editors from being activated, disable the TreeListOptionsBehavior.Editable property.

The ReadOnly property specifies the global read-only mode for all columns within the current TreeList, which cannot be overridden for individual columns. To set the read-only status for individual columns, use the column’s TreeListOptionsColumn.ReadOnly property, accessible via the TreeListColumn.OptionsColumn property.
