Questions tagged [textrange]

Represents a selection of content between two TextPointer positions.

The TextRange class introduces the following terminology.

Selection - A TextRange is a selection of content between two positions indicated by TextPointers. One of these positions a fixed anchor with respect to the selection, while the other position is movable. This is similar to how a selection made by a user using the mouse or keyboard behaves.

Current Selection - Because a TextRange always indicates a selection in content, it makes sense to simply refer to the selection indicated by a TextRange as the current selection.

Text Container - A text container is the element that forms the ultimate border for the flow content at hand; the selection indicated by a TextRange always falls within a text container. Currently, a text container must be either a FlowDocument or a TextBlock. Document - The content collectively contained within a text container is referred to as a document. For more information about other related terms like position, see TextPointer.
