When you edit an object in the Designer, you can revert to a previously saved version, undoing changes you entered since the last save. You can revert to the previously saved versions of multiple objects at the same time.
To revert to a previously saved version of an object:
Open the object in the workspace.
Select the object and click Edit > Revert to Saved.
Click Yes. If you selected more than one object, click Yes to All.
The Designer removes all changes entered since the last time you saved the object.
