I sent a support ticket to the telerik admins asking if there were any API methods to determine if the caret is at the start and end of a line.
They responded with a solution so I thought I should share it with everyone else.

Is Caret at Line Start

public static bool IsCaretAtLineStart(RadDocument document)
{
    DocumentPosition endLinePosition = new DocumentPosition(document.CaretPosition);
    endLinePosition.MoveToCurrentLineStart();
 
    if (document.CaretPosition == endLinePosition)
    {
        return true;
    }
 
    return false;
}


Is Caret at Line End

public static bool IsCaretAtLineEnd(RadDocument document)
{
    DocumentPosition endLinePosition = new DocumentPosition(document.CaretPosition);
    endLinePosition.MoveToCurrentLineEnd();
 
    if (document.CaretPosition == endLinePosition)
    {
        return true;
    }
 
    return false;
}


I hope this helps you as it did myself.

Thanks,

Rob
