【问题描述】：
这是我对 silverlight NumericUpDown 控件的风格。我想将 TabIndex 设置为 Style of control 。

这是我的 NumericUpDownControl 的 XAML 实现
<StackPanel Style="{StaticResource StackPanelStyle_LableValue}">
<TextBlock Text="{Binding Path=ViewItem.Strength, Source={StaticResource LocalizedStrings }}" Style="{StaticResource TextBlockStyle}" />
<inputToolkit:NumericUpDown Style="{StaticResource NumericUpdownStyle_Strength}"
Value="{Binding RightSpecGlassStrength, Mode=TwoWay, ValidatesOnNotifyDataErrors=True, NotifyOnValidationError=True}"
TabIndex="5" />
</StackPanel>
我希望在 NumericUpDown 的 XAML 实现中定义的 TabIndex 属性应该在 NumericUpDown 控件样式中定义的“TextBox”中继承。
或者
是否有任何其他方法可以将 Parent 属性分配给在控件模板中定义的子项。 即如果 NumericUpDown，则 NumericUpDown 到在样式内部定义的文本框的 TabIndex
如何设置？？

控件模板中的 TabIndex="{TemplateBidning TabIndex}" 对我有用....
