Expanded

Occurs when the IsExpanded property changes from true to false.

Declaration

public event RoutedEventHandler Expanded

Event Type

Type	Description
System.Windows.RoutedEventHandler	Type: System.Windows.RoutedEventHandler This event occurs when a TreeViewItemAdv is collapsed so that child elements are hidden.

Examples

The following example shows how to assign an event handler for the Expanded event to a TreeViewItemAdv and how to define the event handler in the code-behind.

<TreeViewItemAdv Header="Employee1"
                 Name="Employee1Data"
                 IsExpanded="True"
                 Collapsed="OnCollapsed"
                 Expanded="OnExpanded">
    <TreeViewItemAdv Header="Work Days"
                     Name="EmployeeWorkDays"
                     IsSelected="True">
        <TreeViewItemAdv Header="Tuesday" />
        <TreeViewItemAdv Header="Friday"/>
    </TreeViewItemAdv>
</TreeViewItemAdv>
<TreeViewItemAdv Header="Employee2"
                 Name="Employee2Data">
    <TreeViewItemAdv Header="Work Days"
                     Name="emp2WorkDays"
                     Selected="GetSchedule"
                     Unselected="SetSchedule">
        <TreeViewItemAdv Header="Monday" />
        <TreeViewItemAdv Header="Wednesday"/>
    </TreeViewItemAdv>
</TreeViewItemAdv>

public void OnExpanded(object sender, RoutedEventArgs e)
{
    //Perform actions when the TreeViewItem is collapsed
}

Selected

Occurs when the IsExpanded property changes from true to false.

Declaration

public event RoutedEventHandler Selected

Event Type

Type	Description
System.Windows.RoutedEventHandler	Type: System.Windows.RoutedEventHandler The event occurs when a TreeViewItemAdv becomes the selected TreeViewItemAdv in a System.Windows.Controls.TreeView control. This event is related to the System.Windows.Controls.TreeView.SelectedItemChangedEvent event that occurs when there is a change in the System.Windows.Controls.TreeView.SelectedItemProperty property of a TreeViewAdv control.

Examples

The following example shows how to assign an event handler for the Selected event to a TreeViewItemAdv, and how to define the event handler in the code-behind.

<TreeViewItem Header="Employee2"
             Name="Employee2Data">
    <TreeViewItem Header="Work Days"
                  Name="emp2WorkDays"

        <TreeViewItem Header="Monday" />
        <TreeViewItem Header="Wednesday"/>
    </TreeViewItem>
</TreeViewItem>

public void GetSchedule(object sender, RoutedEventArgs e)
{
    //Perform actions when a TreeViewItem
    //controls is selected
}

Unselected

Occurs when the IsExpanded property changes from true to false.

Declaration

public event RoutedEventHandler Unselected

Event Type

Type	Description
System.Windows.RoutedEventHandler	Type: System.Windows.RoutedEventHandler The event occurs when the selection changes from this TreeViewItemAdv to another TreeViewItemAdv in a TreeViewAdv control. This event is related to the System.Windows.Controls.TreeView.SelectedItemChangedEvent event that occurs when there is a change in the System.Windows.Controls.TreeView.SelectedItemProperty property of a TreeViewAdv control.

Examples

The following example shows how to assign an event handler for the Selected event to a TreeViewItemAdv, and how to define the event handler in the code-behind.

<TreeViewItem Header="Employee2"
             Name="Employee2Data">
    <TreeViewItem Header="Work Days"
                  Name="emp2WorkDays"

        <TreeViewItem Header="Monday" />
        <TreeViewItem Header="Wednesday"/>
    </TreeViewItem>
</TreeViewItem>

public void SetSchedule(object sender, RoutedEventArgs e)
{
    //Perform actions when a TreeViewItem
    //control becomes unselected
}
