Set up
You can set Max Rollbacks for redo and undo operations in edit operations on the property sheet in Settings in the Edit group.
- Max Rollbacks: Check the Max Rollbacks check box. The setting of Max Rollbacks is valid. The text box to the right of Max Rollbacks is used to enter the maximum number of times to redo and undo editing operations on the property sheet.
When the number of times of redoing and undoing edits on the property sheet exceeds the set Max Rollbacks, the user cannot continue to roll back when editing the property sheet again.
When the number of times the user edits the property sheet exceeds the set Max Rollbacks, and the property sheet is updated and edited in the Update Column dialog box, a dialog box will pop up to prompt "History has reached Max Rollbacks." As a result of this update, the previous update operation cannot be reversed. Do you want to continue? If the user clicks the Yes button, the update operation will be executed; otherwise, the update operation will be cancelled.
- Max Objects: Check the Max Objects check box. The setting of Max Objects is valid. The text box on the right side is used to enter the maximum number of objects that can be affected by one rollback operation set by the user. If the number of records updated at one time exceeds the set Max Objects during the update editing operation of the property sheet in the
Update Column dialog box, a dialog box will pop up during the application of the update operation to prompt that "The number of objects updated is greater than set maximum number of objects for word rollback, and this update cannot be rolled back." Do you want to continue? The user's update operation cannot be reversed. If the user clicks the Yes button, the update operation will be executed; otherwise, the update operation will be cancelled.
- Show warning when rollbacks can not be performed: Select the Show warning when rollbacks can not be performed check box. If the number of editing operations or the number of records affected by a single editing operation exceeds the limit set above, so that the editing operation cannot be rolled back, a prompt dialog box will be displayed to ask the user whether to continue the operation; If this checkbox
is unchecked, the prompt dialog box will not be displayed and the editing operation cannot be executed if the number of editing operations or the number of records affected by a single editing operation exceeds the limit set above during the editing operation of the attribute table by the user, resulting in the editing operation cannot be rolled back.
