How to know if content or text is changed

[Valentijn]

Hi all

I would like to know in code behind when the content in the richtextbox has changed. I know there is a 

DocumentContentChanged event, but this event also fires when the user does nothing in the beginning when the radrichtextbox is created and after the document is loaded.
Using the keydown or keyup is not really an option as those dont fire when a user pastes content by use of the mouse.

Did somebody try to do this and know a solution for this?

Best regards

Valentijn

Hi Valentijn,

Currently DocumentContentChanged event is fired when the document is changed and when the content is changed. This behavior is by design.
It will be helpful for us if you could give us any additional information about your scenario in case you need further assistance.

This is the secnario:

- A user opens the radrichtextbox, the save button is disabled
- The previously created document gets loaded from the database and is loaded in the radrichtextbox
- The user edits the document by entering some text or by pasting some text in the radrichtextbox

I want to know when the user edits the document (so when the thrid step happens) to be able to enable the save button.

As I said before I know there is a DocumentContentChanged event, but this event also fires when the user does nothing in the beginning when the radrichtextbox is created and after the document is loaded. Using the keydown or keyup is not really an option as those dont fire when a user pastes content by use of the mouse.

Thank you for any help.

Hi VAlentijn,
We revised this behaviour and in later versions DocumentContentChanged is not raised on document changing (then only DocumentChanged is fired).
