endPosition Property


Indicates a bound of the Find Text operation.


JavaScript Syntax
Object.defineProperty(DocumentViewerFindText.prototype, 'endPosition', 
	get: function(), 
	set: function(value) 
TypeScript Syntax
endPosition: DocumentViewerTextPosition; 

Property Value

A DocumentViewerTextPosition object indicating the page number and index of the bottom of the text search. The default value is null, which indicates the bottom of the last page of the document.


EndPosition allows DocumentViewerText.Find to have an end bound. Its specification with EndPosition also decides the direction of the search.

If EndPosition is found to be "greater than" BeginPosition - meaning a higher page number or character index - the search will be conducted in the "forward" direction, incrementing through the character indices and pages from BeginPosition to EndPosition. Otherwise, the search will be conducted in a "backward" direction, decrementing through the pages and character indices, but still from the BeginPosition to the EndPosition. Thus, to change direction between calls to DocumentViewerText.Find, swap the two properties.

Since a page's text may not yet be parsed when the search bounds are being chosen, both BeginPosition and EndPosition can take -1 as the value for DocumentViewerTextPosition.CharacterIndex. This value will be internally resolved to the index of the final character of the page if and when the page's text is retrieved. If DocumentViewerText.AutoGetText is false, the -1 will not resolve to a real index and the search will return no results for that page.

See Start as a way to change the start of the search from BeginPosition while maintaining BeginPosition as a bound. If FindAll or Loop are true, this could internally create two searches:

  1. Search from start to EndPosition.

  2. If start from (1) was not BeginPosition, and FindAll or Loop is true, search from BeginPosition to start – 1.

The default value is null, meaning the bottom of the final page.
