格式化MultiBinding时间跨度隐藏毫秒 [英] Formatting MultiBinding TimeSpan to hide milliseconds

问题描述

目前我想multibind一个WPF TextBlock的一个时间跨度财产

以下工作：

 < TextBlock中的Horizo​​ntalAlignment =右
 VerticalAlignment =中心
文本={绑定路径= ImportOperationRuntime，的StringFormat ='hh\\： mm\\：SS'}/> 
  

不幸的是，使用一个MultiBinding破坏了的StringFormat和旁边显示毫秒（尽管通过的StringFormat隐藏）。下面的人不工作：

 < TextBlock的Grid.Column =6VerticalAlignment =中心> 
< TextBlock.Text> 
< MultiBinding的StringFormat =总运行时间：{0}> 
<绑定路径=ImportOperationRuntime的StringFormat =HH：毫米：SS/> 
< / MultiBinding> 
< /TextBlock.Text> 
< / TextBlock的> 
 
< TextBlock的Grid.Column =6VerticalAlignment =中心> 
< TextBlock.Text> 
< MultiBinding的StringFormat =总运行时间：{0}> 
<绑定路径=ImportOperationRuntime的StringFormat =hh\：mm\：SS/> 
< / MultiBinding> 
< /TextBlock.Text> 
< / TextBlock的> 
 
< TextBlock的Grid.Column =6VerticalAlignment =中心> 
< TextBlock.Text> 
< MultiBinding的StringFormat =总运行时间：{0}> 
<绑定路径=ImportOperationRuntime的StringFormat =hh\\：mm\\：SS/> 
< / MultiBinding> 
< /TextBlock.Text> 
< / TextBlock的> 
 
< TextBlock的Grid.Column =6VerticalAlignment =中心> 
< TextBlock.Text> 
< MultiBinding的StringFormat =总运行时间：{0}> 
<绑定路径=ImportOperationRuntime的StringFormat =HH：MM：SS/> 
< / MultiBinding> 
< /TextBlock.Text> 
< / TextBlock的> 
  

和非常相同的StringFormats实际MultiBinding使用时不工作（例如：< MultiBinding的StringFormat =总运行时间：{0：hh\\：mm\\：SS}> ）

$ b。 $ b

我应该如何组织我的StringFormat

解决方案

 < MultiBinding的StringFormat =总运行时间：{0：hh\：mm\：SS}> 
<绑定路径=ImportOperationRuntime/> 
< / MultiBinding> 
  

通常，在后面的代码使用一个双反斜线 \\ 转义。
这不是在XAML的情况。一个就足够了。

I'm currently trying to multibind a WPF TextBlock to a TimeSpan property.

The following works:

<TextBlock HorizontalAlignment="Right"
           VerticalAlignment="Center"
           Text="{Binding Path=ImportOperationRuntime, StringFormat='hh\\:mm\\:ss'}" />

Unfortunately, using a MultiBinding "destroys" the StringFormat and displays the milliseconds alongside (though hidden through the StringFormat). The following ones do not work:

<TextBlock Grid.Column="6" VerticalAlignment="Center">
    <TextBlock.Text>
        <MultiBinding StringFormat="Total runtime: {0}">
            <Binding Path="ImportOperationRuntime" StringFormat="hh':'mm':'ss" />
        </MultiBinding>
    </TextBlock.Text>
</TextBlock>

<TextBlock Grid.Column="6" VerticalAlignment="Center">
    <TextBlock.Text>
        <MultiBinding StringFormat="Total runtime: {0}">
            <Binding Path="ImportOperationRuntime" StringFormat="hh\:mm\:ss" />
        </MultiBinding>
    </TextBlock.Text>
</TextBlock>

<TextBlock Grid.Column="6" VerticalAlignment="Center">
    <TextBlock.Text>
        <MultiBinding StringFormat="Total runtime: {0}">
            <Binding Path="ImportOperationRuntime" StringFormat="hh\\:mm\\:ss" />
        </MultiBinding>
    </TextBlock.Text>
</TextBlock>

<TextBlock Grid.Column="6" VerticalAlignment="Center">
    <TextBlock.Text>
        <MultiBinding StringFormat="Total runtime: {0}">
            <Binding Path="ImportOperationRuntime" StringFormat="hh:mm:ss" />
        </MultiBinding>
    </TextBlock.Text>
</TextBlock>

And the very same StringFormats when used in the actual MultiBinding do not work (ex: <MultiBinding StringFormat="Total runtime: {0:hh\\:mm\\:ss}">).

How should I structure my StringFormat?

解决方案

<MultiBinding StringFormat="Total runtime: {0:hh\:mm\:ss}">
    <Binding Path="ImportOperationRuntime"/>
</MultiBinding>

Normally in code behind you use a double backslash \\ for escaping. This is not the case in xaml. One is enough.
