Remarks

Use the Document.CaretPosition property to get the current cursor (caret) position. The RichEditControl.GetPositionFromPoint method allows you to convert mouse coordinates to a document position.

The DocumentRange.Start and DocumentRange.End positions define a DocumentRange object.

Use the SubDocument.CreatePosition method to obtain an arbitrary position in a document. Call the DocumentPosition.ToInt method to convert a DocumentPosition object to an integer position.

The code sample below obtains a range that starts from the retrieved position:

C#

Document document = server.Document;
document.LoadDocument("Documents\\Grimm.docx", DocumentFormat.OpenXml);
DocumentPosition myStart = document.CreatePosition(69);
DocumentRange myRange = document.CreateRange(myStart, 216);

VB.NET

Dim document As Document = server.Document
document.LoadDocument("Documents\Grimm.docx", DocumentFormat.OpenXml)
Dim myStart As DocumentPosition = document.CreatePosition(69)
Dim myRange As DocumentRange = document.CreateRange(myStart, 216)
