Allow modifying the Undo/Redo Stack

I bind the TelerikEditor Value to a property that is reloaded with different unrelated content. The editor keeps the Undo/Redo stack so for the "second" content I can Undo back to the "first" content. I'd like to be able to clear the Undo stack.

Hi Vitaly,

If I understand correctly, hiding the Editor with CSS should achieve the described goal, yes?

The opposite of this case would be even more useful: after I hide the editor and show it again, I want to keep the undo history if the editor Value has not been updated.

The use scenario is something like a custom image picker: instead of putting a floating window on top of the editor - hide the editor, show your custom image picker at 100% available space, then switch back.

Hi Greg,

Please open a separate thread or ticket about this - I am not aware of such an issue and it is best if it gets its dedicated place and not interfere with the core of the current thread.

Hello Marin.

It appears that there is a bug in the Editor, as when I attempt to do what you suggested (reload the business object and hence the bound property value) the Editor does not reflect the reloaded property value - it still shows the most recent edits.

I think there is a problem in the control not updating its internal Value property when the bound parameter is changed.

In order to force the control to refresh I have to remove it from the DOM and then add it back.

Hello Greg,

This feature request is to control the list of operations available in the undo-redo button commands (which you can clear off  by hiding the editor, re-rendering, and showing it again, as that will make a fresh instance).

If you want to undo all the changes, you should change the Value to the original your app can still have (either a stored copy in-memory in the app, or from the database). Nevertheless, even for that, there is some value in being able to clear the list without re-initializing the component, and if you feel that way, Vote for this too. Resetting the content programmatically, however, is not a feature from the editor, but from the app.

I agree that this would be very useful - the ability to undo all changes at once made to the editor.
