WPF：TextBox materialDesign - 如何对齐 HintAssist.Hint

Question

所以我有这个 TexBox:

<TextBox Height="30"
         BorderThickness="0"
         materialDesign:TextFieldAssist.HasFilledTextField="False"
         materialDesign:TextFieldAssist.HasOutlinedTextField="False"
         materialDesign:TextFieldAssist.DecorationVisibility="Hidden"
         materialDesign:TextFieldAssist.UnderlineBrush="Transparent"
         materialDesign:TextFieldAssist.TextBoxViewMargin="10,3,0,0"
         materialDesign:TextFieldAssist.HasClearButton="True"
         materialDesign:HintAssist.Hint="Search"
         materialDesign:HintAssist.HelperTextFontSize="12"
         materialDesign:HintAssist.IsFloating="False"/>

我想将我的提示（在我的例子中是搜索）放在 TexBox 的中心。

我能找到的是更改 TextFieldAssist.TextBoxViewMargin 但当然这也会影响输入 text。

只需将此代码添加到文本框：

<TextBox.Resources>
            <Style TargetType="{x:Type materialDesign:SmartHint}">
                <Setter Property="HorizontalAlignment" Value="Center"/>
            </Style>
</TextBox.Resources>

示例

<TextBox Height="30"
     BorderThickness="0"
     materialDesign:TextFieldAssist.HasFilledTextField="False"
     materialDesign:TextFieldAssist.HasOutlinedTextField="False"
     materialDesign:TextFieldAssist.DecorationVisibility="Hidden"
     materialDesign:TextFieldAssist.UnderlineBrush="Transparent"
     materialDesign:TextFieldAssist.TextBoxViewMargin="10,3,0,0"
     materialDesign:TextFieldAssist.HasClearButton="True"
     materialDesign:HintAssist.Hint="Search"
     materialDesign:HintAssist.HelperTextFontSize="12"
     materialDesign:HintAssist.IsFloating="False">
        <TextBox.Resources>
            <Style TargetType="{x:Type materialDesign:SmartHint}">
                <Setter Property="HorizontalAlignment" Value="Center"/>
            </Style>
        </TextBox.Resources>
     
    </TextBox>
