Ejemplos

En el ejemplo siguiente se muestra cómo usar los BlockUIContainer elementos para hospedar UIElement elementos dentro del contenido del flujo.

<FlowDocument ColumnWidth="400">
  <Section Background="GhostWhite">
    <Paragraph>
      A UIElement element may be embedded directly in flow content
      by enclosing it in a BlockUIContainer element.
    </Paragraph>
    <BlockUIContainer>
      <Button>Click me!</Button>
    </BlockUIContainer>
    <Paragraph>
      The BlockUIContainer element may host no more than one top-level
      UIElement.  However, other UIElements may be nested within the
      UIElement contained by an BlockUIContainer element.  For example,
      a StackPanel can be used to host multiple UIElement elements within
      a BlockUIContainer element.
    </Paragraph>
    <BlockUIContainer>
      <StackPanel>
        <Label Foreground="Blue">Choose a value:</Label>
        <ComboBox>
          <ComboBoxItem IsSelected="True">a</ComboBoxItem>
          <ComboBoxItem>b</ComboBoxItem>
          <ComboBoxItem>c</ComboBoxItem>
        </ComboBox>
        <Label Foreground ="Red">Choose a value:</Label>
        <StackPanel>
          <RadioButton>x</RadioButton>
          <RadioButton>y</RadioButton>
          <RadioButton>z</RadioButton>
        </StackPanel>
        <Label>Enter a value:</Label>
        <TextBox>
          A text editor embedded in flow content.
        </TextBox>
      </StackPanel>
    </BlockUIContainer>
  </Section>
</FlowDocument>

En la ilustración siguiente se muestra cómo se representa este ejemplo.

En el ejemplo siguiente se muestra cómo usar la Child propiedad mediante programación.

Section secx = new Section();
Paragraph par1 = new Paragraph(new Run(" Text to precede the button... "));
Paragraph par2 = new Paragraph(new Run(" Text to follow the button... "));

// Create a new button to be hosted in the section.
Button buttonx = new Button();
buttonx.Content = "Click me!";

// Create a new BlockUIContainer, and assign the button 
// as the UI container's child.
BlockUIContainer uiCont = new BlockUIContainer();
uiCont.Child = buttonx;

// Add the text runs and UI container to the paragraph, in order.
secx.Blocks.Add(par1);
secx.Blocks.Add(uiCont);
secx.Blocks.Add(par2);

Dim secx As New Section()
Dim par1 As New Paragraph(New Run(" Text to precede the button... "))
Dim par2 As New Paragraph(New Run(" Text to follow the button... "))

' Create a new button to be hosted in the section.
Dim buttonx2 As New Button()
buttonx2.Content = "Click me!"

' Create a new BlockUIContainer, and assign the button 
' as the UI container's child.
Dim uiCont2 As New BlockUIContainer()
uiCont2.Child = buttonx2

' Add the text runs and UI container to the paragraph, in order.
secx.Blocks.Add(par1)
secx.Blocks.Add(uiCont2)
secx.Blocks.Add(par2)

Comentarios

Un BlockUIContainer puede hospedar directamente no más de un UIElement elemento secundario. Sin embargo, el elemento secundario hospedado por un BlockUIContainer puede hospedar elementos secundarios propios.

En XAML, el ajuste de un UIElement objeto en es BlockUIContainer equivalente a establecerlo UIElement como valor de la Child propiedad .
