    Hello,

    Let's say I have a RichTextBlock of width 200 and I have an inline run that wraps, I want to be able to determine the selectable region. More specifically, how can I determine what region the Run occupies on Line 1, Line 2, etc?

    <RichTextBlock Width="200" FontSize="20" TextWrapping="Wrap">
    <RichTextBlock.Blocks>
        <Paragraph >
            <Paragraph.Inlines>
                <Run Text="My selectable run" />
            </Paragraph.Inlines>
        </Paragraph>
    </RichTextBlock.Blocks>
</RichTextBlock>

    Hi Dev Help,

    By ElementStart  and  ElementEnd from Run class we should be able to know the TextPointer position of the Run block. But I cannot see there exist any method that can get the line number of the selectable region, or even any valuable that can calculate the line number.
