cursor current position for radrichtextbox?

How to get the cursor current position for radrichtextbox?

like the Silver light control text box has property SelectionStart to get the current position of the cursor.

Hello,

You can access the current caret position through the RadDocument.CaretPosition property. More on this you can learn in the online help articles on positioning and selection.

I am having an issue with positioning the cursor via the .MoveToPosition() method.  When I do this, the cursor gets placed correctly, but the document window adjusts so that the cursor is the last line that is shown. 

For example, my RadRichTextBox displays 10 lines at any given time and I have 50 lines of text in the document.  If I move the cursor to a place in the text that is on the 30th line, it will put the 30th line at the bottom of the display.  I would like for it to put the selected line in the middle of the displayed area OR not move the display at all, just move the cursor.

Hope this makes sense....

Tks.

Hi Brian,

A ready-to-use method for such functionality is not available out of the box. However you can use the following code:

DocumentPosition positionYouWantTheCaretOn = ...//logic finding the needed position
this.editor.Document.CaretPosition.MoveToPosition(positionYouWantTheCaretOn );
this.editor.ScrollToVerticalOffset(this.editor.Document.CaretPosition.Location.Y - this.editor.ActualHeight / 2);

I hope this helps.
