How to get current textpointer/offset of RichTextBlock in a scrollviewer

Question

I have a richtextblock in a scrollviewer, the content of the richtextblock is very long. When I scroll the content, how can I get the first word or first TextPointer or first Offset which we can see in the scrollviewer.

Answer 1

Hi InfiXu,

Take a look at VerticalSnapPointsAlignment and HorizontalSnapPointsAlignment. I think you will need it.

Best Regards,

Answer 2

Sorry, it is not about snap points, I just want to get the first textpointer we can see in the scrollviewer

Answer 3

Hi InfiXu,

Oh, sorry, I made a mistake, I did not go detail into the snap point.

We can get the HorizontalOffset and VerticalOffset, I think you could use this two parameters to calculate the offset of scollview child control.
