## Remarks
Use the <xref:System.Windows.Controls.Primitives.Selector.IsSelected%2A> attached property to select an item in the <xref:System.Windows.Controls.Primitives.Selector> when you do not explicitly create the item container. An item container is a class that represents an item in the <xref:System.Windows.Controls.Primitives.Selector>. <xref:System.Windows.Controls.TabItem>, <xref:System.Windows.Controls.ListBoxItem>, and <xref:System.Windows.Controls.ComboBoxItem> are item containers for the controls that inherit from <xref:System.Windows.Controls.Primitives.Selector>, and each defines an **IsSelected** property.
If you do not explicitly create an item container, Windows Presentation Foundation (WPF) implicitly creates one and sets the **IsSelected** property on the item container to the value of <xref:System.Windows.Controls.Primitives.Selector.IsSelected%2A?displayProperty=nameWithType>. This is the only time <xref:System.Windows.Controls.Primitives.Selector.IsSelected%2A?displayProperty=nameWithType> is read. <xref:System.Windows.Controls.Primitives.Selector.IsSelected%2A?displayProperty=nameWithType> is not updated if the selection on the item changes.
If you explicitly create an item container, you should use the **IsSelected** property on that class.
<a name="dependencyPropertyInfo_IsSelected"></a>
## Dependency Property Information
|||
|-|-|
|Identifier field|<xref:System.Windows.Controls.Primitives.Selector.IsSelectedProperty>, registered as Attached|
|Metadata properties set to `true`|<xref:System.Windows.FrameworkPropertyMetadata.BindsTwoWayByDefault%2A>|
## Examples
The follow example creates a <xref:System.Windows.Controls.ListBox> that contains two <xref:System.Windows.Controls.CheckBox> controls. The example does not explicitly create a <xref:System.Windows.Controls.ListBoxItem> for either <xref:System.Windows.Controls.CheckBox>, so it sets <xref:System.Windows.Controls.Primitives.Selector.IsSelected%2A?displayProperty=nameWithType> directly on each <xref:System.Windows.Controls.CheckBox>. To illustrate that <xref:System.Windows.Controls.Primitives.Selector.IsSelected%2A?displayProperty=nameWithType> is not updated, the example binds the <xref:System.Windows.Controls.Primitives.ToggleButton.IsChecked%2A> property of the first checkbox to <xref:System.Windows.Controls.Primitives.Selector.IsSelected%2A?displayProperty=nameWithType>. When the user unselects the item in the <xref:System.Windows.Controls.ListBox>, the <xref:System.Windows.Controls.CheckBox> remains checked. Likewise, checking or unchecking the <xref:System.Windows.Controls.CheckBox> does not affect whether the <xref:System.Windows.Controls.CheckBox> is selected in the <xref:System.Windows.Controls.ListBox>. The example binds <xref:System.Windows.Controls.Primitives.ToggleButton.IsChecked%2A> of the second <xref:System.Windows.Controls.CheckBox> to <xref:System.Windows.Controls.ListBoxItem.IsSelected%2A?displayProperty=nameWithType>. In this case, unselecting the item in the <xref:System.Windows.Controls.ListBox> causes the checkbox to be unchecked, and unchecking the checkbox also unselects the item.
```xaml
<ListBox Name="listBox1" SelectionMode="Multiple">
<CheckBox Selector.IsSelected="True"
IsChecked="{Binding RelativeSource={RelativeSource Self},
Path=(Selector.IsSelected), Mode=TwoWay}">
CheckBox.IsChecked is bound to Selector.IsChecked, which is set only
once.
</CheckBox>
<CheckBox ListBox.IsSelected="True"
IsChecked="{Binding RelativeSource={RelativeSource
AncestorType={x:Type ListBoxItem}},
Path=IsSelected, Mode=TwoWay}">
CheckBox.IsChecked is bound to ListBoxItem.IsChecked, which is
updated throughout the duration of the application.
</CheckBox>
</ListBox>

## Remarks
You can set the <xref:System.Windows.Controls.Primitives.Selector.IsSynchronizedWithCurrentItem%2A> property to `true` to ensure that the item selected always corresponds to the <xref:System.Windows.Controls.ItemCollection.CurrentItem%2A> property in the <xref:System.Windows.Controls.ItemCollection>. For example, suppose that there are two <xref:System.Windows.Controls.ListBox> controls with their <xref:System.Windows.Controls.ItemsControl.ItemsSource%2A> property set to the same source. Set <xref:System.Windows.Controls.Primitives.Selector.IsSynchronizedWithCurrentItem%2A> to `true` on both list boxes to ensure that the selected item in each <xref:System.Windows.Controls.ListBox> is the same.

The following example binds two <xref:System.Windows.Controls.ListBox> controls to the same <xref:System.Windows.Controls.ItemsControl.ItemsSource%2A>. Because <xref:System.Windows.Controls.Primitives.Selector.IsSynchronizedWithCurrentItem%2A> is set to `true` on each <xref:System.Windows.Controls.ListBox>, the selected item is always the same for both controls

## Remarks
If a <xref:System.Windows.Controls.Primitives.Selector> supports selecting a single item, the <xref:System.Windows.Controls.Primitives.Selector.SelectedIndex%2A> property returns the index of the selected item. If a <xref:System.Windows.Controls.Primitives.Selector> supports multiple selections, <xref:System.Windows.Controls.Primitives.Selector.SelectedIndex%2A> returns the index of the item that the user selected first.
Setting <xref:System.Windows.Controls.Primitives.Selector.SelectedIndex%2A> in a <xref:System.Windows.Controls.Primitives.Selector> that supports multiple selections clears existing selected items and sets the selection to the item specified by the index. <xref:System.Windows.Controls.Primitives.Selector.SelectedIndex%2A> returns -1 if selection is empty.
If you set <xref:System.Windows.Controls.Primitives.Selector.SelectedIndex%2A> to a value less that -1, an <xref:System.ArgumentException> is thrown. If you set <xref:System.Windows.Controls.Primitives.Selector.SelectedIndex%2A> to a value equal or greater than the number of child elements, the value is ignored.
