Move Caret to top visible line?

created 12 years ago

How do I move the cursor (caret) to the top-most visible line on the screen, in the Rich Edit?

Thanks.

Hi,
There is no standard method to accomplish this task. However, you can try the following approach to search and calculate the required position:

C#
DocumentPosition documentPosition = null;  
int searchLocation1 = 0;  
int searchLocation2 = 0;  

do {  
    searchLocation1+=2;  
    searchLocation2++;  
    Point clientPoint = new Point(searchLocation1, searchLocation2);  
    Point documentPoint = Units.PixelsToDocuments(clientPoint, richEditControl1.DpiX, richEditControl1.DpiY);  
    documentPosition = richEditControl1.GetPositionFromPoint(documentPoint);  
} while (documentPosition == null);  

richEditControl1.Document.CaretPosition = documentPosition;  

richEditControl1.Focus();

Attached is a complete code example. I hope this information helps you.
Thanks,
Alessandro.
