How to: Handle the MouseDoubleClick Event for Each Item in a ListView

To handle an event for an item in a ListView, you need to add an event handler to each ListViewItem. When a ListView is bound to a data source, you don't explicitly create a ListViewItem, but you can handle the event for each item by adding an EventSetter to a style of a ListViewItem.

Example

The following example creates a data-bound ListView and creates a Style to add an event handler to each ListViewItem.

<!--XmlDataProvider is defined in a ResourceDictionary, 
    such as Window.Resources-->
<XmlDataProvider x:Key="InventoryData" XPath="Books">
    <x:XData>
        <Books xmlns="">
            <Book ISBN="0-7356-0562-9" Stock="in" Number="9">

            <Book ISBN="0-7356-1377-X" Stock="in" Number="5">
                <Title>Introducing Microsoft .NET</Title>

            <Book ISBN="0-7356-1448-2" Stock="out" Number="4">
                <Title>Microsoft C# Language Specifications</Title>
                <Summary>The C# language definition</Summary>
            </Book>
        </Books>
    </x:XData>
</XmlDataProvider>
<!--The Style is defined in a ResourceDictionary, 
    such as Window.Resources-->
<Style TargetType="ListViewItem">
    <EventSetter Event="MouseDoubleClick" Handler="ListViewItem_MouseDoubleClick"/>
</Style>
<ListView ItemsSource="{Binding Source={StaticResource InventoryData}, XPath=Book}">
    <ListView.View>
        <GridView>
            <GridViewColumn Width="300" Header="Title" 
                            DisplayMemberBinding="{Binding XPath=Title}"/>
            <GridViewColumn Width="150" Header="ISBN" 
                            DisplayMemberBinding="{Binding XPath=@ISBN}"/>
        </GridView>
    </ListView.View>
</ListView>

The following example handles the MouseDoubleClick event.

void ListViewItem_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{

    XmlElement book = ((ListViewItem) sender).Content as XmlElement;

    if (book == null)
    {
        return;
    }

    if (book.GetAttribute("Stock") == "out")
    {
        MessageBox.Show("Time to order more copies of " + book["Title"].InnerText);
    }
    else
    {
        MessageBox.Show(book["Title"].InnerText + " is available.");
    }
}
Private Sub ListViewItem_MouseDoubleClick(ByVal sender As Object, _
                                          ByVal e As MouseButtonEventArgs)

    Dim lvi As ListViewItem = CType(sender, ListViewItem)
    Dim book As XmlElement = CType(lvi.Content, XmlElement)

    If book.GetAttribute("Stock") = "out" Then
        MessageBox.Show("Time to order more copies of " + book("Title").InnerText)
    Else
        MessageBox.Show(book("Title").InnerText + " is available.")
    End If
End Sub

Note

Although it is most common to bind a ListView to a data source, you can use a style to add an event handler to each ListViewItem in a non-data-bound ListView regardless of whether you explicitly create a ListViewItem. For more information about explicitly and implicitly created ListViewItem controls, see ItemsControl.
