I have a
TextBlock in WPF. I write many lines to it, far exceeding its vertical height. I expected a vertical scroll bar to appear automatically when that happens, but it didn’t. I tried to look for a scroll bar property in the Properties pane, but could not find one.
How can I make vertical scroll bar created automatically for my
TextBlock once its contents exceed its height?
Clarification: I would rather do it from the designer and not by directly writing to the XAML.
Wrap it in a scroll viewer:
<ScrollViewer> <TextBlock /> </ScrollViewer>
NOTE this answer applies to a
TextBlock (a read-only text element) as asked for in the original question.
If you want to show scroll bars in a
TextBox (an editable text element) then use the
ScrollViewer attached properties:
<TextBox ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Auto" />
Valid values for these two properties are
