# Text Position

**TextPosition** is a position in the text of a **RadFixedDocument**. They enable keeping track of a "current" position in the document (i.e. a caret) and lay the foundations of document selection.

## Creation

One can create a **TextPostion** for a particular document, page and index using one of the constructors:

* **TextPosition(RadFixedDocument document)**

* **TextPosition(RadFixedPage page)**

* **TextPosition(RadFixedPage page, int index)**

* **TextPosition(TextPosition position)**

The constructors that accept a **RadFixedPage** as parameter create a **TextPosition** for the particular page. The offset you specify will be the offset in the current page in terms of number of characters. If you pass only the **RadFixedDocument** instance, a **TextPosition** for the first page will be created. In case you want to make a copy of a **TextPosition**, you can opt for the constructor listed last.

## Members

The members that the **TextPosition** class exposes are:

* **Properties**

  * **Index**: The integer offset of the text position into the page.

  * **Page**: The **RadFixedPage** that the position belongs to.

* **Methods**: Provide the means for navigation in the document and have self-explanatory names and arguments:

  * **MoveToNextPosition()**

  * **MoveToPreviousPosition()**

  * **MoveToPosition(TextPosition position)**

  * **MoveToNextWord()**

  * **MoveToPreviousWord()**

  * **MoveToCurrentWordStart()**

  * **MoveToCurrentWordEnd()**

  * **MoveToLineStart()**

  * **MoveToLineEnd()**

  * **MoveLineUp()**

  * **MoveLineDown()**

  * **MoveToStartOfDocument()**

  * **MoveToEndOfDocument()**

* **Events**:

  * **PositionChanging**- occurs just before the position is moved;

  * **PositionChanged** - occurs after the position has moved.

The caret position of **RadFixedDocument** is also a **TextPosition** object and all methods and properties listed above could be used with it as well. Here is an example:

#### CaretPosition

```C#
this.radPdfViewer1.PdfViewerElement.Document.CaretPosition.MoveToEndOfDocument();

```

```VB.NET
Me.RadPdfViewer1.PdfViewerElement.Document.CaretPosition.MoveToEndOfDocument()
```

This will not only move the caret to the end of the document, but will also scroll the document to bring it into view, as the view port follows the caret.
