ListItem Class

A flow content element that represents a particular content item in an ordered or unordered List.

Namespace: System.Windows.Documents
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

[ContentPropertyAttribute("Blocks")] 
public class ListItem : TextElement
/** @attribute ContentPropertyAttribute("Blocks") */ 
public class ListItem extends TextElement
ContentPropertyAttribute("Blocks") 
public class ListItem extends TextElement
<ListItem>
  Blocks
</ListItem>

Content Model: ListItem enforces a strong content model for child content. See TextElement Content Model Overview for more information about the ListItem content model.

ListItem elements must be contained by a List element.

The following example shows how to define a List using XAML.

<FlowDocument Background="GhostWhite">
  <List MarkerOffset="25" MarkerStyle="UpperRoman" StartIndex="5">
    <ListItem>
      <Paragraph>Boron</Paragraph>
    </ListItem>
    <ListItem>
      <Paragraph>Carbon</Paragraph>
    </ListItem>
    <ListItem>
      <Paragraph>Nitrogen</Paragraph>
    </ListItem>
    <ListItem>
      <Paragraph>Oxygen</Paragraph>
    </ListItem>
    <ListItem>
      <Paragraph>Fluorine</Paragraph>
    </ListItem>
    <ListItem>
      <Paragraph>Neon</Paragraph>
    </ListItem>
  </List>
</FlowDocument>

The following example shows how to create and populate a List programmatically.

List listx = new List();
// Set the space between the markers and list content to 25 DIP.
listx.MarkerOffset = 25;
// Use uppercase Roman numerals.
listx.MarkerStyle = TextMarkerStyle.UpperRoman;
// Start list numbering at 5.
listx.StartIndex = 5;

// Create the list items that will go into the list.
ListItem liV = new ListItem(new Paragraph(new Run("Boron")));
ListItem liVI = new ListItem(new Paragraph(new Run("Carbon")));
ListItem liVII = new ListItem(new Paragraph(new Run("Nitrogen")));
ListItem liVIII = new ListItem(new Paragraph(new Run("Oxygen")));
ListItem liIX = new ListItem(new Paragraph(new Run("Fluorine")));
ListItem liX = new ListItem(new Paragraph(new Run("Neon")));

// Finally, add the list items to the list.
listx.ListItems.Add(liV);
listx.ListItems.Add(liVI);
listx.ListItems.Add(liVII);
listx.ListItems.Add(liVIII);
listx.ListItems.Add(liIX);
listx.ListItems.Add(liX);

The following figure shows how this example renders.

The following example shows how to define a nested List (lists within lists) using XAML.

<FlowDocument Background="GhostWhite">
  <List MarkerOffset="25" MarkerStyle="UpperRoman" StartIndex="5">
    <ListItem>
      <Paragraph>Boron</Paragraph>
      <List Margin="0" Padding="0"  >
        <ListItem Margin="40,0,0,0">
          <Paragraph>Symbol: B</Paragraph>
        </ListItem>
        <ListItem Margin="40,0,0,0">
          <Paragraph>Atomic Mass: 10.811</Paragraph>
        </ListItem>
      </List>

      <List Margin="0" Padding="0"  >
        <ListItem Margin="40,0,0,0">

        </ListItem>
        <ListItem Margin="40,0,0,0">

        <ListItem Margin="40,0,0,0">

        </ListItem>
        <ListItem Margin="40,0,0,0">
          <Paragraph>Atomic Mass: 18.9984032</Paragraph>
