Template for textbox behavior

Question

Hi people,

I'm trying to make a template for a textbox, but it is strange behavior. See this xaml code.

This code Works:

 <Page.Resources>
        <Style TargetType="TextBox">
            <Setter Property="Height" Value="80" />
            <Setter Property="Foreground" Value="White" />
        </Style>
        <ControlTemplate TargetType="TextBox" x:Key="bordaTexto">
            <Border CornerRadius="5" BorderBrush="#FF2B6789" BorderThickness="4">
                <TextBox />
            </Border>
        </ControlTemplate>
       
    </Page.Resources>

    <Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
        <TextBox Text="teste1" HorizontalAlignment="Left" Margin="23,157,0,0" TextWrapping="Wrap" VerticalAlignment="Top"  Width="349" Template="{StaticResource bordaTexto}"/>
        <TextBox Text="teste2" HorizontalAlignment="Left" Margin="411,157,0,0" TextWrapping="Wrap" VerticalAlignment="Top"  Width="349" Template="{StaticResource bordaTexto}"/>

    </Grid>

This code doesn't work(difference is element <TextBox /> inside <Border>):

 

 <Page.Resources>
        <Style TargetType="TextBox">
            <Setter Property="Height" Value="80" />
            <Setter Property="Foreground" Value="White" />
        </Style>
        <ControlTemplate TargetType="TextBox" x:Key="bordaTexto">
            <Border CornerRadius="5" BorderBrush="#FF2B6789" BorderThickness="4">

            </Border>
        </ControlTemplate>
       
    </Page.Resources>

    <Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
        <TextBox Text="teste1" HorizontalAlignment="Left" Margin="23,157,0,0" TextWrapping="Wrap" VerticalAlignment="Top"  Width="349" Template="{StaticResource bordaTexto}"/>
        <TextBox Text="teste2" HorizontalAlignment="Left" Margin="411,157,0,0" TextWrapping="Wrap" VerticalAlignment="Top"  Width="349" Template="{StaticResource bordaTexto}"/>

    </Grid>

Thanks...

 

Answer 1

What is the strange behavior? How does the actual behavior differ from what you expect?

I don't understand because I need add <textBox /> block.
