### Description

Contains all editable regions in the main text or another part of a document. It is a collection of objects of the type [EditableRegion](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/editableregion/llms-full.txt). A collection object can be obtained with the [TextControl.EditableRegions](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol-wpf/textcontrol/editableregions-property/llms-full.txt), the [HeaderFooter.EditableRegions](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/headerfooter/editableregions-property/llms-full.txt) or the [TextFrame.EditableRegions](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/textframe/editableregions-property/llms-full.txt) property. The EditableRegionCollection class implements the IEnumerable and the ICollection interfaces. When the [EditMode](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol-wpf/textcontrol/editmode-property/llms-full.txt) property of a Text Control has been set to `ReadAndSelect`, editable regions can still be edited, either by everyone or depending on the [UserName](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/editableregion/username-property/llms-full.txt) property by a certain user.
