WPF RichTextBox触摸滚动不起作用

Question

I have a rich text box control, that I wish to be able to scroll by touch.

The MSDN documentation says I should set this property: https://msdn.microsoft.com/en-us/library/system.windows.controls.scrollviewer.panningmode(v=vs.110).aspx

<RichTextBox ScrollViewer.PanningMode="Both" >

However, this makes no difference, touch events still select text and instead of scrolling. Any ideas?

So creating a scrollable object is a bit tricky in WPF. You need to put the RichTextBox inside the ScrollViewer . Then you need to set the PanningMode to either horizontal or vertical (or you can try to set it to auto which is also recommended). For example you should get something like this:

<ScrollViewer CanContentScroll="True" PanningMode="VerticalOnly">
            <RichTextBox> 
                       //content here
            </RichTextBox>
</Scrollviewer>
