C＃“如果”绑定值 [英] C# 'if' Binding value

问题描述

我有一个由绑定填充，在一个名为类楼列表视图。

这里是我的代码示例：

 < DataTemplate的数据类型=房子> 
< TextBlock的文本={结合sold_status}/> 
< / DataTemplate中> 
  

正如你所看到的，我的变量名是 sold_status 。这是一个布尔。

我要显示为<$ C要么卖还是不出售 $ C> 1 和 0 分别。

能否在时尚的？基于价值的语句

所以才让你可以想像我想达到什么：

 <数据类型的DataTemplate =房子> 
< TextBlock的文本=（{结合sold_status} == 1）'卖'其他'不卖'/> 
< / DataTemplate中> 
  

解决方案

您需要创建与DataTriggers样式根据需要设置的属性。你也可以使用一个转换器，但改变基于基础数据的UI控件的属性到底是什么触发/风格是什么。

..其实，我可以看到你'重新基本上'sold_status转换'到一些文字。为此，使用转换器。我会后一个简单的例子。

看到这里最多的回答：的 WPF：显示一个布尔值" YES接/"否]。 - 它有一个例子转换器类，你可以重新调整

I've got a list view that is populated by a Binding, on a class named House.

Here's an example of my code:

<DataTemplate DataType="house">
    <TextBlock Text="{Binding sold_status}" />
</DataTemplate>

As you can see, one of my variable names is sold_status. This is a bool.

I want to show either "SOLD" or "NOT SOLD" for 1 and 0 respectively.

Is it possible to fashion an if statement based on the value?

So just so that you can visualise what I want to achieve:

<DataTemplate DataType="house">
    <TextBlock Text="({Binding sold_status} == 1) 'SOLD' else 'NOT SOLD'" />
</DataTemplate>

解决方案

You'll want to create a Style with DataTriggers in to set the properties as needed. You could also use a converter, but changing UI control properties based on underlying data is exactly what triggers/styles are all about.

..In fact, I can see you're basically 'converting' sold_status to a bit of text. For that, use a converter. I'll post a quick example..

See the top answer here: WPF: Display a bool value as "Yes" / "No" - it has an example converter class you could repurpose.
