我如何将段落数据绑定到TextBlock?
如何使用 Paragraph
对象并将其数据绑定到TextBlock以用于DataTemplate?
一个简单的绑定什么都不做,只是Paragraph对象的 ToString()
。
How would I take a Paragraph
object and databind them to the TextBlock for use in a DataTemplate?
A plain bind does nothing, just a ToString()
of the Paragraph object.
InLines属性将让我添加一个手动组成Paragraph的TextRun的列表,但这不能绑定到,我可以用一个基于绑定的解决方案来实现。
The InLines property would let me add a list of TextRun's that make up the Paragraph manually, but that can't be bound to and I could really do with a binding based solution.
这是一个使用嵌套的例子物品控制。不幸的是,它会使一个TextBlock每个Inline而不是将整个段落放入一个TextBlock:
Here's an example using a nested ItemsControl. Unfortunately, it will make one TextBlock per Inline instead of putting the whole Paragraph into one TextBlock:
<Grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid.Resources>
<FlowDocument x:Key="document">
<Paragraph><Run xml:space="preserve">This is the first paragraph. </Run><Run>The quick brown fox jumps over the lazy dog.</Run></Paragraph>
<Paragraph><Run xml:space="preserve">This is the second paragraph. </Run><Run>Two driven jocks help fax my big quiz.</Run></Paragraph>
<Paragraph><Run xml:space="preserve">This is the third paragraph. </Run><Run>Sphinx of black quartz, judge my vow!</Run></Paragraph>
</FlowDocument>
<DataTemplate DataType="{x:Type Paragraph}">
<ItemsControl ItemsSource="{Binding Inlines}" IsHitTestVisible="False">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</DataTemplate>
</Grid.Resources>
<ListBox ItemsSource="{Binding Blocks, Source={StaticResource document}}"/>
</Grid>
如果您想要每个元素一个Paragraph,您应该按照建议使用一个Paragraph,并使用只读RichTextBox,或做这个人从TextBlock 导出,以便Inlines属性可以绑定。
If you want one Paragraph per element you should probably do as suggested and use a read-only RichTextBox, or do what this person did and derive from TextBlock so that the Inlines property can be bound.
