Exposes methods and properties to support UI Automation client access to a span of continuous text in a text container that implements ITextProvider.

Remarks
Implemented on a UI Automation provider that must support the TextPattern control pattern.
A TextPatternRange can represent an insertion point, a subset, or all of the text in a TextPattern container.
Methods
| AddToSelection() |
Adds to the collection of highlighted text in a text container that supports multiple, disjoint selections. |
| Clone() |
Returns a new ITextRangeProvider identical to the original ITextRangeProvider and inheriting all properties of the original. |
| Compare(ITextRangeProvider) |
Returns a value that indicates whether the span (the Start endpoint to the End endpoint) of a text range is the same as another text range. |
| CompareEndpoints(TextPatternRangeEndpoint, ITextRangeProvider, TextPatternRangeEndpoint) |
Returns a value that specifies whether two text ranges have identical endpoints. |
| ExpandToEnclosingUnit(TextUnit) |
Expands the text range to the specified text unit. |
| FindAttribute(Int32, Object, Boolean) |
Returns a text range subset that has the specified attribute value. |
| FindText(String, Boolean, Boolean) |
Returns a text range subset that contains the specified text. |
| GetAttributeValue(Int32) |
Retrieves the value of the specified attribute across the text range. |
| GetBoundingRectangles() |
Retrieves a collection of bounding rectangles for each fully or partially visible line of text in a text range. |
| GetChildren() |
Retrieves a collection of all embedded objects that fall within the text range. |
| GetEnclosingElement() |
Returns the innermost control that encloses the text range. |
| GetText(Int32) |
Retrieves the plain text of the range. |
| Move(TextUnit, Int32) |
Moves the text range the specified number of text units. |
| MoveEndpointByRange(TextPatternRangeEndpoint, ITextRangeProvider, TextPatternRangeEndpoint) |
Moves one endpoint of a text range to the specified endpoint of a second text range. |
| MoveEndpointByUnit(TextPatternRangeEndpoint, TextUnit, Int32) |
Moves one endpoint of the text range the specified number of text units within the document range. |
| RemoveFromSelection() |
Removes a highlighted section of text, corresponding to the caller's Start and End endpoints, from the collection of highlighted text in a text container that supports multiple, disjoint selections. |
| ScrollIntoView(Boolean) |
Causes the text control to scroll vertically until the text range is visible in the viewport. |
| Select() |
Highlights text in the text control corresponding to the text range Start and End endpoints. |
