有条件的触发器WPF [英] Conditional triggers WPF

问题描述

大家好，
我仍然对WPF中的触发器感到困惑，所以请帮忙.我在这里完全迷路了.以下是我的代码的一部分.

Hello All,
I still get a bit confused wen it comes to triggers in WPF so please help.I am totally lost here .Following is part of my code.

<MultiDataTrigger>
                           <MultiDataTrigger.Conditions>
                             I want to put a condition here saying if select button is clicked(the select button is a ribbon toggle button) then only on mouse over the decorator shoulds be visble
                           </MultiDataTrigger.Conditions>
                           <Setter TargetName="Decorator" Property="Visibility" Value="Visible"/>
                       </MultiDataTrigger>

<Trigger Property="IsMouseOver" Value="true">
                            <Setter TargetName="Decorator" Property="Visibility" Value="Visible"/>
                        </Trigger>

我希望我对这个问题很清楚.功能区按钮在另一个xaml文件中
我想要的就是在鼠标悬停上单击功能区按钮选择"后，装饰器应该可见，否则隐藏，如果我们可以在按钮后面的代码中执行此操作，也可以单击确定，但是我不确定如何更改在另一个按钮上设置的属性xaml文件.

在此先感谢

I hope I am clear with this question.the ribbon button is in another xaml file
All I want is after I click the ribbon button "select" on mouseover the decorator shoulds be visible else hidden if we can do this in code behind on button click also ok but I am not sure how to change the property that is set on another xaml file.

Thanks in advance

推荐答案

通过将资源文件添加到项目中来创建样式资源
在该资源中，定义功能区按钮的样式，然后在style.trigger上定义装饰器的可见性属性

希望这对您有帮助.

Hi,


Create a style resource by adding resource file to your project
In that resource define a style for the ribbon button and on style.trigger define your decorator visibility proeprty

Hope this helps.

如果您希望在上的条件属性，则可以使用 MultiTrigger .

如果您对属性没有依赖性，则可以使用 MultiDataTrigger .

If your have conditions on properties the aren''t Dependency Properties, you can use a MultiDataTrigger.

在有关它们的MSDN主题中有使用这些触发器的示例.

There are examples of the use of these triggers in the MSDN topics about them.
