WPF: TextBox materialDesign - how to Alignment HintAssist.Hint-CodePudding

So I have this 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"/>

And I want to place my Hint (Search in my example) at the center of my TexBox.

Al i can found is to change TextFieldAssist.TextBoxViewMargin but of course this effect the input text as well.

CodePudding user response：

Just add this code to textbox:

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

Example

<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>
