通过结合它可点击链接动态创建的文本 [英] Dynamically created text with clickable links in it via binding

问题描述

我想创建它由一个自己的类的多个项目的列表视图。一个属性是它可以包含在它的一个或多个链接文本。通常，我使用一个TextBlock以获得该内容显示在文本绑定。

I do want to create a listview which consists of many items of an own class. One of the properties is a text which can contain one or more links in it. Normally I use a textblock with a binding on Text to get this content displayed.

现在我确实想被解析链接的文本，然后动态地使这些链接点击。我发现相当长的一段code像<一个href=\"http://stackoverflow.com/questions/2092890/add-hyperlink-to-textblock-wpf\">http://stackoverflow.com/questions/2092890/add-hyperlink-to-textblock-wpf关于如何创建带超级链接的文本块，所以我会被罚款 - 但WPF绑定可在文本属性，因此这并不能帮助我到底

Now I do want those text being parsed for links and then dynamically make those links clickable. I found quite some code like http://stackoverflow.com/questions/2092890/add-hyperlink-to-textblock-wpf on how to create a textblock with hyperlinks so I would be fine - but the WPF binding is available on the Text property so this doesn't help me in the end.

那么，有没有在列表视图的项目（的ObservableCollection或类似）的列表结合有文本中点击链接的方式？

So is there a way for binding for a list of items (ObservableCollection or similar) in a listview to have clickable links within text?

Thx提前

推荐答案

我有一个简单的解决方案。

I have a simple solution.

使用DataTemplate中，你可以指定一个类的模板，说LinkItem其中包含文本和超链接。

Using the DataTemplate, you could specify an template for a class, say LinkItem which contains your text, and a hyper-link.

public class LinkItem
{
    public string Text { get; set; }
    public string Hyperlink { get; set; }

    public LinkItem(string text, string hyperlink)
    {
        Text = text;
        Hyperlink = hyperlink;
    }
}

// XAML Data template
<DataTemplate DataType="{x:Type HyperlinkDemo:LinkItem}">
    <TextBlock>
        <TextBlock Text="{Binding Text}" Margin="1" />
        <Hyperlink>
            <TextBlock Text="{Binding Hyperlink}" Margin="1" />
        </Hyperlink>
    </TextBlock>
</DataTemplate>

// List box definition
<ListBox ItemsSource="{Binding LinkItems}" />

尼斯和简单。只是一堆LinkItem添加到您的收藏LinkItems，你会得到的文本和超链接在你的列表框中的一些不错的组合。

Nice and simple. Just add a bunch of LinkItem to your LinkItems collection and you will get some nice mix of text and hyperlink in your list box.

您也可以扔在一个命令，在LinkItem类让事情变得更有趣和命令绑定到超链接。

You could also throw in a command in the LinkItem class to make things a little more interesting and bind the command to the hyperlink.

<Hyperlink Command="{Binding HyperlinkCommand}"> ....
