UWP TextBox VerticalContentAlignment

Question

I have faced up with the following problem: I cannot vertically align content inside TextBox. I have image icon and TextBox for user input beside, but text in TextBox has default top Alignment. I can change it by setting the VerticalAlignment="Center", but then the height of the TextBox becomes less than I need (it should has 43px height). I have tried VerticalContentAlignment="Center, but it does not work either. I know only one possible solution: set padding inside TextBox, but I don't like that idea. Maybe there other solutions which I do not know?

Thanks in advance!

Here is part of my code:

<Grid Margin="15,0,15,10">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" />
                    <ColumnDefinition Width="*" />
                </Grid.ColumnDefinitions>
                <Image Grid.Column="0" 
                       Source="/Assets/TextInputIcons/Money.png" 
                       Style="{StaticResource InputFieldIconsStyle}" />
                <TextBox Grid.Column="1" 
                         PlaceholderText="Sum" 
                         Style="{StaticResource NumberedTextBox}" />
            </Grid>

Answer 1

It can easily be done by creating a style as follows:

• Right click on the TextBox, Edit Template => Create a Copy.
• At the bottom of the generated style look for (ScrollViewer x:Name="ContentElement") for the content and (ContentControl x:Name="PlaceholderTextContentPresenter") for the text placeholder. Add (VerticalAlignment="Center") to both of them.

Example:

<Page.Resources>
        <Style x:Key="CenterTextBoxStyle" TargetType="TextBox">
            <Setter Property="MinWidth" Value="{ThemeResource TextControlThemeMinWidth}"/>
            <Setter Property="MinHeight" Value="{ThemeResource TextControlThemeMinHeight}"/>
            <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>
            <Setter Property="Background" Value="{ThemeResource SystemControlBackgroundAltHighBrush}"/>
            <Setter Property="BorderBrush" Value="{ThemeResource SystemControlForegroundChromeDisabledLowBrush}"/>
            <Setter Property="SelectionHighlightColor" Value="{ThemeResource SystemControlHighlightAccentBrush}"/>
            <Setter Property="BorderThickness" Value="{ThemeResource TextControlBorderThemeThickness}"/>
            <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/>
            <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}"/>
            <Setter Property="ScrollViewer.HorizontalScrollMode" Value="Auto"/>
            <Setter Property="ScrollViewer.VerticalScrollMode" Value="Auto"/>
            <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Hidden"/>
            <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Hidden"/>
            <Setter Property="ScrollViewer.IsDeferredScrollingEnabled" Value="False"/>
            <Setter Property="Padding" Value="{ThemeResource TextControlThemePadding}"/>
            <Setter Property="Template">

                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Page.Resources>

This way the Text and the PlaceholderText always stay at the center no matter what are the height or the font of the TextBox.

Answer 2

I have the problem that like you,and I know that is the Font size error.And TextBox can make it's height sure the Font size,but you set VerticalContentAlignment="Center" And I have a solution,that make a Border

    <Border Grid.Column="1">
        <TextBox/>
    </Border>

and it's BorderThickness as the TextBox's BorderThickness and it's brush as the TextBox's brush. And you set the TextBox VerticalAlignment="Center" and BorderThickness ="0"
