DatePicker模板，滑鼠移過時出現邊框

我有一個奇怪的問題，

我的DatePicker在中間顯示一些邊框。我不知道它是從哪里來的。

我改變了DatePickerTextBox的所有屬性，但它沒有任何改變。

這里是XAML :

 <Window.Resources>/span>
    <Style TargetType="{x:Type DatePicker}">/span>
        <Setter Property="Template"> 
            <Setter.Value>/span>
                <ControlTemplate TargetType="{x:Type DatePicker}"/span>>
                    <Border x: 名稱="MainBorder" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="1" CornerRadius="5"> 
                        <Grid x: Name="PART_Root" Margin="2"> 
                            <Grid.ColumnDefinitions>/span>
                                <ColumnDefinition Width="*"/span> />
                                <ColumnDefinition Width="Auto"/span> />
                            </Grid.ColumnDefinitions> 
                            <DatePickerTextBox x:Name="Part_TextBox"
                                   BorderThickness="0"。
                                   BorderBrush="透明"
                                   HorizontalContentAlignment="Stretch" 
                                   Padding="{TemplateBinding Padding}" 
                                   VerticalContentAlignment="Center"。
                                   Visibility="Visible"/span>
                                   SelectionBrush="#FF6F5DF5"/span> 
                                   FocusVisualStyle="{x:Null}" 
                                   Grid.Column="0" Margin="0,3,0,0">
                                
                                <DatePickerTextBox.Style> 
                                    <Style>
                                        <Setter Property="TextBox. BorderThickness" Value="0"/> 
                                    </Style>/span>
                                </DatePickerTextBox.Style> 
                            </DatePickerTextBox> 
                            <Button x: Name="PART_Button" HorizontalAlignment="Right" Margin="0,0,0。 333,0.333" Width="24">

                                        <Setter Property="Template"/span>>
                                            <Setter.Value>/span>
                                                <ControlTemplate TargetType="{x:Type Button}"/span>>

                    <ControlTemplate.Triggers> 
                        < Trigger Property="IsDropDownOpen" Value="True">
                            < Setter TargetName="MainBorder"/span> 屬性="BorderBrush" Value="#FF6F5DF5"/>

< DatePicker Margin="10,260,0, 0" VerticalAlignment="Top"  Uid="Date de naissance *" FontSize="12" 字體大小="12" 高度="40" BorderThickness="0" HorizontalAlignment="Left""Left" Width="181"/span> FontFamily="Poppins" Background="#FFFEFEFE" BorderBrush="#FF9A9A" Foreground="#FF727272" /> 

這里看起來是這樣的 :

有什么想法嗎？

uj5u.com熱心網友回復：

DatePickerTextBox有它自己的模板，邊界和邊界的觸發器在這里被定義/硬編碼。

你需要在 DatePickerTextBox 的模板中處理這些問題。

改變：

<DatePickerTextBox.Style><
     <Style>
         <Setter Property="TextBox. BorderThickness" Value="0"/> 
     </Style>>
</DatePickerTextBox.Style> 

致：

<DatePickerTextBox.Style> 
    <Style TargetType="{x:Type DatePickerTextBox}">/span>
         <Setter Property="Control.Template">/span>
               <Setter.Value>/span>
                     <ControlTemplate>/span>
                          <TextBox x: Name="PART_TextBox" BorderThickness="0"
                                                             Text="{Binding Path=SelectedDate, RelativeSource={RelativeSource AncestorType={x:Type DatePicker}}"/span> />
                     </ControlTemplate> 
               </Setter.Value>/span>
         </Setter>/span>
     </Style>>
</DatePickerTextBox.Style> 

而且它應該能作業。
