Hello,
I have an Edit Content Page with a Rad Editor Control, first when the user creates a new content, say a Forum Post the content is Saved into the DataBase but when I reload the contents from the Database and then verify them with the contents of Rad Editor I noticed that even if I didn't make any changes the content is not the same, I was comparing string to string content, (DB vs loaded Editor content from DB)
Is there anyway to check whether the contents of the Rad Editor have changed? I want to do this Server Side (Code Behind), is there a property or a field that checks for that?
Thank you.

Hi,
The content area of RadEditor is an editable IFRAME element which uses the Rich Text Editing (RTE) engine of the browser. The RTE engine automatically validates the content and changes it in different cases: for example IE converts all tags to uppercase, converts the relative links to absolute, corrects the non properly closed tags, etc. In addition to that RadEditor runs its own built-in content filters in order to make the content XHTML compliant.
You can disable some or all of the RadEditor content filters but you cannot stop the RTE engine of the different browsers to validate and change the content. That is why it is very hard or impossible to implement a reliable validation mechanism, because it is not possible to stop the browsers validation.

Hello Rumen I don't really want to compare the content I just want to check if Something has changed, is it possible to do that in Code Behind? or even client side?
