使用DataTemplate 中定义的DataTrigger。

以下示例在选中CheckBox 时将按钮的Backgound 设置为红色：

<DataTemplate>
  <StackPanel Orientation="Horizontal"
              HorizontalAlignment="Right">
    ...

    <Button Name="btnFilterfile" />    
    <CheckBox Name="chkBxKill" />
  </StackPanel>

  <DataTemplate.Triggers>
    <DataTrigger Binding="{Binding ElementName=chkBxKill, Path=IsChecked}" Value="True">
      <Setter TargetName="btnFilterfile" Property="Background" Value="Red" />
    </DataTrigger>
  </DataTemplate.Triggers>
</DataTemplate>
