Nasıl Yapılır: Görünümde Veri Sıralama
This example describes how to sort data in a view.
Örnek
The following example creates a simple ListBox and a Button:
<Window x:Class="ListBoxSort_snip.Window1"
xmlns="https://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="https://schemas.microsoft.com/winfx/2006/xaml"
Title="ListBoxSort_snip" Height="300" Width="300">
<DockPanel>
<ListBox Name="myListBox" DockPanel.Dock="Top">
<ListBoxItem>my</ListBoxItem>
<!--Or you can set the content this way:-->
<!--<ListBoxItem Content="my"/>-->
<ListBoxItem>1</ListBoxItem>
<ListBoxItem>Sort</ListBoxItem>
<ListBoxItem>3</ListBoxItem>
<ListBoxItem>ListBox</ListBoxItem>
<ListBoxItem>2</ListBoxItem>
</ListBox>
<Button Click="OnClick" Width="30" Height="20" DockPanel.Dock="Top">Sort</Button>
</DockPanel>
</Window>
The Click event handler of the button contains logic to sort the items in the ListBox in the descending order. You can do this because adding items to a ListBox this way adds them to the ItemCollection of the ListBox, and ItemCollection derives from the CollectionView class. If you are binding your ListBox to a collection using the ItemsSource property, you can use the same technique to sort.
Private Sub OnClick(ByVal sender As Object, ByVal e As RoutedEventArgs)
myListBox.Items.SortDescriptions.Add(New SortDescription("Content", ListSortDirection.Descending))
End Sub
private void OnClick(object sender, RoutedEventArgs e)
{
myListBox.Items.SortDescriptions.Add(
new SortDescription("Content", ListSortDirection.Descending));
}
As long as you have a reference to the view object, you can use the same technique to sort the content of other collection views.
