<TextBlock Height="23" HorizontalAlignment="Left" Margin="16,18,0,0" Name="textBlock1" Text="TextBlock" VerticalAlignment="Top" />

</Grid>

1. add style for textBlock

        <Style   TargetType="{x:Type TextBlock}">

            <Setter Property="HorizontalAlignment" Value="Left"/>

            <Setter Property="VerticalAlignment" Value="Center"/>

            <Setter Property="Foreground" Value="#ffffffff"/>

            <Setter Property="FontSize" Value="16px"/>

            <Setter Property="MinHeight" Value="50"/>

            <Setter Property="Margin" Value="16,6,0,6"/>

            InitializeComponent();

            Loaded += new RoutedEventHandler(MainWindow_Loaded);

        }

 

        void MainWindow_Loaded(object sender, RoutedEventArgs e)

        {

            textBlock1.Text = "Tasti con caartteri";

        }

1.  Run application ,display as bellow:

 

1. Why? I set Text Property textBlock1.Text = "Tasti con caartteri" , but display on ly “Tasti con”

The last word is missing.

If  you  change  any    letter  in this word,it display ok.

If  you  add  any    letter  in this word,it display ok.

If  you delete style  <Setter Property="TextWrapping" Value="Wrap"/> , ,it display ok

If  you delete style  <Setter Property="Padding" Value="4,8,4,4"/>, ,it display ok.

If  you change fontsize to 15px,it display ok.

1. Please find a reason for this,thank you!
