Editor - Track Changes, How it works?.

[Anbu]

Guys,

We r planning to buy Telerik Asp Ajax controls. I would like to know how the track changes works in the editor?. I got requirement to integrate track changes facility in editor, When some one edits the rich text content and submit the content for approval, the Approver/Manager should be able view the track changes. So I would like to know, how the track changes works?. Will the track changes is retained over postbacks. Is the track changes contents are stored inside the actual data?.

Can you provide me the full details of how the track changes works in Telerik Editor?.

Thanks,
Anbu

Hi Anbu,

The TrackChanges dialog is using  a helper class DiffEngine located in the Telerik.Web.UI.Editor.Diff namespace. The method that does the actual work is GetDiffs(curContent, initContent). This method compares the two parameters and modifies the result to apply the decorations.

Current and initial contents are stored in hidden fields in the dialog passed as an arguments to the TrackChangesDialog RadEditor's command. In order to get the initial and current content you can use the corresponding client-side methods - get_initialContent(), get_html(true).

I believe the following forum thread will be of great help to achieve the required functionality:
