HeaderedContentControl Content Model Overview

.NET Framework 3.0

This content model overview describes the supported content for a HeaderedContentControl. The TabItem class is a type of HeaderedContentControl.

A HeaderedContentControl has two content properties:

This topic contains the following sections.

Using the Header Property

A HeaderedContentControl's Header content is typically used to label or identify the control's primary contents. For example, a TabItem's header is the content that appears on the tab, while its primary content appears in the panel. In the following illustration, "Font", "Character Spacing", and "Text Effects" are examples of header content.

HeaderedContentControl

The Header property supports both text and UIElement content.

Adding Text Content

The Header property accepts text. The following example shows how to add text content to a control's header.

<TabItem Header="Some Header Content">
</TabItem>

TabItem myTabItem = new TabItem();
myTabItem.Header = "Some Header Content";

Adding UIElement Content

The Header property can also accept a single UIElement as its content. Examples of UIElements include Image, StackPanel, and Rectangle. The following example shows how to add a UIElement to a control's header.

<TabItem>
  <TabItem.Header>
    <Image Source="Images\fish.png" Width="16" Height="16"/>
  </TabItem.Header>
</TabItem>

TabItem myTabItem2 = new TabItem();
Image myImage = new Image();
myImage.Width = 16;
myImage.Height = 16;
BitmapImage myBitmapImage = new BitmapImage();
myBitmapImage.BeginInit();
myBitmapImage.UriSource = new Uri(@"pack://application:,,,/images/fish.png");
myBitmapImage.EndInit();
myImage.Source = myBitmapImage;
myTabItem2.Header = myImage;

There are a wide variety of UIElement types that can be used as header content, including those that belong to the following type families.

Using the Content Property

The content of a HeaderedContentControl is typically used to contain the control's primary contents. For example, the content of a TabItem is what appears when the TabItem is selected.

The Content property which the HeaderedContentControl inherits from ContentControl supports both text and UIElement content.

Adding Text Content

The Content property accepts text. The following example shows how to add text content to a control.

<TabItem Header="My Header">
  Some text content.
</TabItem>

TabItem myTabItem3 = new TabItem();
myTabItem3.Header = "MyHeader";
myTabItem3.Content = "Some text content";

Adding UIElement Content

The Content property can also accept a single UIElement as its content. Examples of such elements include Image, StackPanel, and Rectangle. The following example shows how to add a UIElement to a control.

<TabItem Header="MyHeader">
  <Image Source="Images\fish.png" Width="16" Height="16"/>
</TabItem>

TabItem myTabItem4 = new TabItem();
Image myImage2 = new Image();
myImage2.Width = 16;
myImage2.Height = 16;
BitmapImage myBitmapImage2 = new BitmapImage();
myBitmapImage2.BeginInit();
myBitmapImage2.UriSource = 
  new Uri(@"pack://application:,,,/images/fish.png");
myBitmapImage2.EndInit();
myImage2.Source = myBitmapImage2;
myTabItem4.Header = "MyHeader";
myTabItem4.Content = myImage2;
