在WPF重写模板化按钮的命令 [英] Overriding a templated Button's Command in WPF

问题描述

我有一个控件模板我使用改变几个按钮 S上的外观和行为。我只希望的按钮为可点击并执行绑定命令的一部分，所以我增加了一个按钮在控件模板，并将其绑定到模板的命令属性。

I have a ControlTemplate that I'm using to change the appearance and behavior of several Buttons. I only want part of the Button to be clickable and to execute the bound Command, so I added a Button within the ControlTemplate and bound it to the template's Command property.

我遇到的问题是，因为我定义了命令的模板按钮结合，它不管我点击模板的哪一部分的执行。

The problem I'm having is that since I am defining the Command binding on the templated Button, it executes regardless of which part of the template I am clicking.

在下面的例子中，你可以点击边框执行命令。我如何改变它，使命令只执行，当你在模板中点击按钮？

In the below example you can click the Border and execute the Command. How do I change it so that the Command only executes when you click the Button within the template?

<ControlTemplate x:Key="ButtonControlTemplate" TargetType="{x:Type Button}">
    <Border BorderThickness="10" BorderBrush="Black">
        <Button
            Command="{TemplateBinding Command}"
            CommandParameter="{TemplateBinding CommandParameter}" >
            <ContentPresenter Content="{TemplateBinding Content}" />
        </Button>
    </Border>
</ControlTemplate>

...

<Button
    Command="{Binding Path=SomeViewmodelCommand}"
    CommandParameter="{Binding Path=SomeViewmodelCommandParameter}"
    Content="Click"
    Template="{StaticResource ButtonControlTemplate}" />

我不认为我能模板不同的元素（如边框），因为我还需要在命令传递不知何故，和附加属性仍然给我相同的行为。

I don't think I can template a different element (like the Border) because I still need to pass in the Command somehow, and attached properties would still give me the same behavior.

推荐答案

另一种方法是重新模板的另一个控件，如边界并在模板内的按钮使用的RoutedCommand。你可以绑定到内置RoutedCommands，如ApplicationCommands.Save和在XAML为含有控制之一，添加的CommandBinding该特定命令。让我知道，如果一些code将是有益的。

Another alternative is to re-template another control, such as Border and use a RoutedCommand on the Button inside the template. You could bind it to one of the built-in RoutedCommands, such as ApplicationCommands.Save and in the XAML for the containing control, add a CommandBinding for that particular command. Let me know if some code would be helpful.
