Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
A text buffer that contains projections of other text buffers, composed of a list of tracking spans of those buffers. The buffers that contribute to the projection buffer are called source buffers, and the tracking spans that describe the contributed regions are called source spans.

Properties
| ContentType |
Gets the content type of the text in the buffer. (Inherited from ITextBuffer) |
| CurrentSnapshot |
The current snapshot of the contents of the projection buffer. (Inherited from IProjectionBufferBase) |
| EditInProgress |
Determines whether an edit operation is currently in progress on the ITextBuffer. (Inherited from ITextBuffer) |
| Properties |
The collection of properties controlled by the property owner. (Inherited from IPropertyOwner) |
| SourceBuffers |
The set of ITextBuffer objects that directly contribute to the projection buffer. (Inherited from IProjectionBufferBase) |
Methods
| ChangeContentType(IContentType, Object) |
Changes the IContentType for this ITextBuffer. (Inherited from ITextBuffer) |
| CheckEditAccess() |
Determines whether edit operations on this text buffer are permitted on the calling thread. If TakeThreadOwnership() has previously been called, edit operations are permitted only from the same thread that made that call. (Inherited from ITextBuffer) |
| CreateEdit() |
Creates an ITextEdit object that handles compound edit operations on this buffer. (Inherited from ITextBuffer) |
| CreateEdit(EditOptions, Nullable<Int32>, Object) |
Creates an ITextEdit object that handles compound edit operations on this buffer. (Inherited from ITextBuffer) |
| CreateReadOnlyRegionEdit() |
Creates an IReadOnlyRegionEdit object that handles adding or removing read-only regions from this buffer. (Inherited from ITextBuffer) |
| Delete(Span) |
Deletes a span of characters from the buffer. (Inherited from IProjectionBufferBase) |
| DeleteSpans(Int32, Int32) |
Deletes a sequence of source spans from the projection buffer. |
| GetReadOnlyExtents(Span) |
Gets a list of read-only regions that overlap the given span. (Inherited from ITextBuffer) |
| Insert(Int32, String) |
Inserts the given |
| InsertSpan(Int32, ITrackingSpan) |
Inserts a tracking span into the list of source spans. |
| InsertSpan(Int32, String) |
Inserts a literal string into the list of SourceSpans. |
| InsertSpans(Int32, IList<Object>) |
Inserts a list of ITrackingSpan objects and/or literal strings into the list of source spans in the order in which they appear in the list. |
| IsReadOnly(Int32, Boolean) |
Determines whether a text insertion would be prohibited at |
| IsReadOnly(Int32) |
Determines whether a text insertion would be prohibited at |
| IsReadOnly(Span, Boolean) |
Determines whether a text modification or deletion would be prohibited at |
| IsReadOnly(Span) |
Determines whether a text modification or deletion would be prohibited at |
| Replace(Span, String) |
Replaces a span of characters with different text. This is equivalent to first deleting the text to be replaced and then inserting the new text. (Inherited from IProjectionBufferBase) |
| ReplaceSpans(Int32, Int32, IList<Object>, EditOptions, Object) |
Replaces a sequence of source spans with a new list of ITrackingSpan objects and/or literal strings. |
| TakeThreadOwnership() |
Claims ownership of this buffer for the current thread. All subsequent modifications of this ITextBuffer must be made from the current thread, or else an InvalidOperationException will be raised. (Inherited from ITextBuffer) |
Events
| Changed |
Occurs when a non-empty ITextEdit is successfully applied. (Inherited from ITextBuffer) |
| ChangedHighPriority |
Occurs when a non-empty ITextEdit is successfully applied. (Inherited from ITextBuffer) |
| ChangedLowPriority |
Occurs when a non-empty ITextEdit is successfully applied. (Inherited from ITextBuffer) |
| Changing |
Occurs just before a non-empty ITextEdit is applied. (Inherited from ITextBuffer) |
| ContentTypeChanged |
Occurs whenever the IContentType has been changed. (Inherited from ITextBuffer) |
| PostChanged |
Occurs after the Changed event and any resulting edits. (Inherited from ITextBuffer) |
| ReadOnlyRegionsChanged |
Occurs when an IReadOnlyRegionEdit has created or removed read-only regions. (Inherited from ITextBuffer) |
| SourceBuffersChanged |
Raised when source buffers are added or deleted by virtue of the addition or deletion of source spans. This event is raised before the SourceSpansChanged event is raised. |
| SourceSpansChanged |
Raised when source spans are added or deleted. It is not raised when the contents of a source span change, for example when a source span becomes empty. When a nonempty span is added or deleted, the SourceBuffersChanged event will be raised first. The sequence of events is: 1) SourceBuffersChanged, 2) SourceSpansChanged, 3) ITextBuffer.Changed. The SourceSpansChanged event is raised first). |
