I have a minimalist UserControl
containing a single TextBlock
which I prototype as follows:
<Grid>
<TextBlock x:Name="textBlockExt" x:FieldModifier="public"/>
</Grid>
public partial class TextBlockExt : UserControl
{
public TextBlockExt()
{
InitializeComponent();
DataContext = this;
}
public string Text
{
get => textBlockExt.Text;
set { textBlockExt.Text = value.ToUpper(); } // to be expanded later
}
}
I then consume the control by
<Grid>
<StackPanel>
<local:TextBlockExt FontSize="30" x:Name="txb" Text="Hello World" TextBlock.TextAlignment="Center"/>
<Button Content="To Upper" Width="100" Click="Button_Click"/>
</StackPanel>
</Grid>
And it's code behind is
public MainWindow()
{
InitializeComponent();
txb.textBlockExt.TextWrapping = TextWrapping.WrapWithOverflow;
}
private void Button_Click(object sender, RoutedEventArgs e)
{
txb.Text = "one two three four five six seven eight";
}
I don't like the code in the MainWindow
constructor above and need to know how to set the T extWrapping
in the XAML.
Add a property TextWrapping to your TextBlockExt class. Use the same way you did for the Text property:
public TextWrapping TextWrapping {
get => txtBlockExt.TextWrapping;
set { txtBlockExt.TextWrapping = value: }
}
