基于PresentationFramework.Aero覆盖WPF TextBox中的默认样式

基于PresentationFramework.Aero覆盖WPF TextBox中的默认样式，是指在Windows Presentation Foundation (WPF)应用程序中，通过使用PresentationFramework.Aero样式库来自定义TextBox控件的外观和行为。

在WPF中，TextBox是一个常用的控件，用于接收用户输入。然而，默认的样式可能不总是符合应用程序的需求。因此，可以通过覆盖默认样式来自定义TextBox的外观和行为。

PresentationFramework.Aero是WPF应用程序中常用的样式库，它提供了一组预定义的样式和控件模板，可以用于自定义应用程序的外观和行为。要基于PresentationFramework.Aero覆盖WPF TextBox中的默认样式，可以使用以下步骤：

首先，在应用程序的资源中引入PresentationFramework.Aero样式库。

   <ResourceDictionary>
       <ResourceDictionary.MergedDictionaries>
           <ResourceDictionary Source="/PresentationFramework.Aero;component/themes/Aero.NormalColor.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

然后，在应用程序的资源中定义一个新的样式，以覆盖默认的TextBox样式。

   <Setter.Value>

       <ControlTemplate TargetType="{x:Type TextBox}">

            <Grid>

               <VisualStateManager.VisualStateGroups>

                   <VisualStateGroup x:Name="CommonStates">

                       <VisualState x:Name="Normal" />

                       <VisualState x:Name="MouseOver" />

                       <VisualState x:Name="Disabled">

                           <Storyboard>

                               <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(TextElement.Foreground).(SolidColorBrush.Color)" Storyboard.TargetName="PART_ContentHost">

                                    <EasingColorKeyFrame KeyTime="0" Value="{DynamicResource {x:Static SystemColors.GrayTextColorKey}}" />

                                </ColorAnimationUsingKeyFrames>

                            </Storyboard>

                        </VisualState>

                       <VisualState x:Name="ReadOnly">

                           <Storyboard>

                               <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(TextElement.Foreground).(SolidColorBrush.Color)" Storyboard.TargetName="PART_ContentHost">

                                    <EasingColorKeyFrame KeyTime="0" Value="{DynamicResource {x:Static SystemColors.ControlDarkColorKey}}" />

                                </ColorAnimationUsingKeyFrames>

                            </Storyboard>

                        </VisualState>

                    </VisualStateGroup>

                   <VisualStateGroup x:Name="FocusStates">

                       <VisualState x:Name="Focused">

                           <Storyboard>

                               <DoubleAnimation Duration="00:00:00.1" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="FocusVisualElement" />

                            </Storyboard>

                        </VisualState>

                       <VisualState x:Name="Unfocused" />

                    </VisualStateGroup>

                   <VisualStateGroup x:Name="ValidationStates">

                       <VisualState x:Name="Valid" />

                       <VisualState x:Name="InvalidUnfocused">

                           <Storyboard>

                               <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Visibility" Storyboard.TargetName="ValidationErrorElement">

                                    <DiscreteObjectKeyFrame KeyTime="0">

                                        <DiscreteObjectKeyFrame.Value>

                                           <Visibility>Visible</Visibility>
