在WPF TextBlock的自动垂直滚动条？ [英] Automatic vertical scroll bar in WPF TextBlock?

问题描述

我在WPF中有一个的TextBlock 。我写了许多行了，这远超过其垂直高度。我希望这种情况发生时，垂直滚动条自动出现，但事实并非如此。我试图寻找在属性面板中滚动条属性，但没能找到。

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.

我怎样才能使垂直滚动条对我的<$ C $自动创建C>的TextBlock 一旦它的内容超过其高度

How can I make vertical scroll bar created automatically for my TextBlock once its contents exceed its height?

澄清：我宁愿从设计师做的，而不是通过直接写入到XAML

Clarification: I would rather do it from the designer and not by directly writing to the XAML.

推荐答案

包装在滚动查看器：

<ScrollViewer>
    <TextBlock />
</ScrollViewer>

注意这个答案适用于的TextBlock （只读文本元素）作为要求在原来的问题。

NOTE this answer applies to a TextBlock (a read-only text element) as asked for in the original question.

如果你想显示滚动条在文本框（可编辑的文本元素），然后使用的ScrollViewer 附加属性：

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" />

有关这两个属性的有效值为禁用 ，自动，隐藏和可见。

Valid values for these two properties are Disabled, Auto, Hidden and Visible.
