WPF 自定义按钮的命令绑定不起作用
我创建了一个继承 Button 类的自定义按钮。我添加了一些依赖属性，我需要让用户指定按钮的外观。
该按钮看起来很棒，并且依赖属性也按照我的意愿工作。但是，无论我如何尝试，Command 属性都不起作用。
这是我的示例：
public partial class CustomButton : Button
{
... //some dependency property
public CustomButton()
{
...//do some initialization
//I tried checking the Command property over here but it seems like always to be NULL?!
}
}
我的 XAML：
<Button x:Class="CustomButton"
xmlns:.....>
<Button.Resources>
<Style TargetType="Button" x:Key="CustomButtonStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<StackPanel Orientation="Horizontal" Background="Transparent" Height="22">
......more things behind...
</Style>
</Button.Resources>
<Button.Style>
<Style TargetType="{x:Type Button}" BasedOn="{StaticResource CustomButtonStyle}">
</Style>
</Button.Style>
</Button>
我在其他 Windows 控件中使用它，如下所示：
<Controls:CustomButton Command="{Binding NewCommand}" ToolTip="AddNew"/>
该命令总是不被执行，为什么？我错过了什么吗？ 请帮忙。谢谢。
I created a custom button that inherits the Button class. I added some dependency property that I need to let the user specify how the button will look like.
The button looks great and the dependency property also worked as I wished. But however, the Command property doesn't work no matter how I try.
Here's my sample:
public partial class CustomButton : Button
{
... //some dependency property
public CustomButton()
{
...//do some initialization
//I tried checking the Command property over here but it seems like always to be NULL?!
}
}
My XAML:
<Button x:Class="CustomButton"
xmlns:.....>
<Button.Resources>
<Style TargetType="Button" x:Key="CustomButtonStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<StackPanel Orientation="Horizontal" Background="Transparent" Height="22">
......more things behind...
</Style>
</Button.Resources>
<Button.Style>
<Style TargetType="{x:Type Button}" BasedOn="{StaticResource CustomButtonStyle}">
</Style>
</Button.Style>
</Button>
I used it in my other windows control like this:
<Controls:CustomButton Command="{Binding NewCommand}" ToolTip="AddNew"/>
The command always not being executed, why? Did I miss out anything?
Please help. Thanks.

猜测你的模板只会让实际点击按钮变得困难。作为实验，尝试将根
StackPanel的背景设置为纯色Red而不是Transparent，看看这样是否更容易单击。Guessing your template just makes it difficult to actually click on the button. As an experiment, try setting the background of the root
StackPanelto solidRedrather thanTransparentand see if that makes it easier to click.
