TextPointer.IsAtInsertionPosition Property
Gets a value that indicates whether the current position is an insertion.
Namespace: System.Windows.Documents
Assembly: System.Windows (in System.Windows.dll)
Property Value
Type: System.Booleantrue if the current position is an insertion position; otherwise, false.
An insertion position is a position where new content may be added without breaking any semantic rules for the associated content. In practice, an insertion position is anywhere in content where a caret may be positioned. An example of a valid TextPointer position that is not an insertion position is the position between two adjacent Paragraph tags (that is, between the closing tag of the preceding paragraph and the opening tag of the next paragraph).
