这是错误的方式来做你想做的事。这是做到这一点的“正确”方法。这里有相当多的样板代码，但你已经习惯了。
编写一个按钮视图模型并为您的主视图模型提供一个 ObservableCollection：
#region ViewModelBase Class
public class ViewModelBase : INotifyPropertyChanged
{
#region INotifyPropertyChanged
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void OnPropertyChanged([System.Runtime.CompilerServices.CallerMemberName] string propName = null) =>
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propName));
#endregion INotifyPropertyChanged
}
#endregion ViewModelBase Class
#region MainViewModel Class
public class MainViewModel : ViewModelBase
{
public MainViewModel()
{
ButtonItems.Add(new ButtonItemViewModel("First Command", "First Item", () => MessageBox.Show("First Item Executed")));
ButtonItems.Add(new ButtonItemViewModel("Second Command", "Second Item", () => MessageBox.Show("Second Item Executed")));
}
#region ButtonItems Property
public ObservableCollection<ButtonItemViewModel> ButtonItems { get; }
= new ObservableCollection<ButtonItemViewModel>();
#endregion ButtonItems Property
}
#endregion MainViewModel Class
#region ButtonItemViewModel Class
public class ButtonItemViewModel : ViewModelBase
{
public ButtonItemViewModel(String cmdName, String text, Action cmdAction)
{
CommandName = cmdName;
Text = text;
Command = new DelegateCommand(cmdAction);
}
#region Text Property
private String _text = default(String);
public String Text
{
get { return _text; }
set
{
if (value != _text)
{
_text = value;
OnPropertyChanged();
}
}
}
#endregion Text Property
#region CommandName Property
private String _commandName = default(String);
public String CommandName
{
get { return _commandName; }
private set
{
if (value != _commandName)
{
_commandName = value;
OnPropertyChanged();
}
}
}
#endregion CommandName Property
public ICommand Command { get; private set; }
}
#endregion ButtonItemViewModel Class
public class DelegateCommand : ICommand
{
public DelegateCommand(Action action)
{
_action = action;
}
private Action _action;
public event EventHandler CanExecuteChanged;
public bool CanExecute(object parameter)
{
return true;
}
public void Execute(object parameter)
{
_action?.Invoke();
}
}
使 MainViewModel 成为您窗口的 DataContext：
public MainWindow()
{
InitializeComponent();
DataContext = new MainViewModel();
}
以下是如何在 XAML 中将所有内容放在一起：
<Grid>
<StackPanel Orientation="Vertical">
<GroupBox Header="Buttons">
<ItemsControl ItemsSource="{Binding ButtonItems}" HorizontalAlignment="Left">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button
Margin="2"
MinWidth="80"
Content="{Binding Text}"
Command="{Binding Command}"
/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</GroupBox>
<GroupBox Header="Edit Buttons">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<ListBox
Grid.Column="0"
Margin="2"
x:Name="ButtonEditorListBox"
ItemsSource="{Binding ButtonItems}"
HorizontalAlignment="Left"
>
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock
Margin="2"
Text="{Binding CommandName}"
/>
<TextBlock
Margin="2"
Text="{Binding Text, StringFormat=': "{0}"'}"
/>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ListBox>
<ContentControl
Grid.Column="1"
Margin="8,2,2,2"
Content="{Binding SelectedItem, ElementName=ButtonEditorListBox}"
>
<ContentControl.ContentTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<TextBlock
Margin="2"
HorizontalAlignment="Stretch"
FontWeight="Bold"
Text="{Binding CommandName, StringFormat={}{0}: }"
/>
<TextBox
Margin="2"
HorizontalAlignment="Stretch"
Text="{Binding Text, UpdateSourceTrigger=PropertyChanged}"
/>
</StackPanel>
</DataTemplate>
</ContentControl.ContentTemplate>
</ContentControl>
</Grid>
</GroupBox>
</StackPanel>
</Grid>
回到你的问题：
每个按钮的样式内部都有一个TextBlock，用于显示按钮的“内容”（因为样式内的边框覆盖了按钮本身的任何内容）。
你做错了样式。非常非常错误。如果您向我展示样式，我可以帮助您解决它。
