In the last blog entry, the new document protection feature of TX Text Control X15 has been explained. Documents can be protected by restricting the formatting and editing of content.

Editable regions are exceptions within protected documents to provide specific users permissions to edit these regions while the rest of the document is read-only.

The TXTextControl.EditableRegion object represents an editable region in a protected document. When the TXTextControl.TextControl.EditMode property of TX Text Control has been set to ReadAndSelect, editable regions can still be edited, either by everyone or depending on the TXTextControl.EditableRegion.UserName property by a certain user.

The following code inserts a new editable region at the currently selected text. The first parameter in the TXTextControl.EditableRegion constructor is the TXTextControl.EditableRegion.UserName property which specifies the name of the user who can edit the region. In the following code, the UserName is null which indicates that every user can edit this region:
