                    ＆LT;＆StackPanel的GT;
                        ＆LT; TextBlock的X：名称=txtDescription保证金=10,0,0,0前景=＃FF030042字号=20文本={绑定描述}/＆GT;
                    ＆LT; / StackPanel的＆GT;
                ＆LT; / StackPanel的＆GT;
            ＆LT; / StackPanel的＆GT;
        ＆LT; / DataTemplate中＆GT;
    ＆LT; /ListBox.ItemTemplate>
＆LT; /列表框＆GT;
 

解决方案

您可以做到这一点落后于selectchanged事件处理altough在code：

 私人无效listLocs_SelectionChanged（对象发件人，SelectionChangedEventArgs E）
    {
        ListBoxItem中myitem = listLocs.SelectedItem为ListBoxItem的;
       刷的SolidColorBrush =新的SolidColorBrush（Color.FromArgb（255,255,0,0））;
       myitem.Background =刷;
    }
 

How can I change selected item's background color that in listbox which has datatemplate in Windows Phone?

I have seen that it can be with Setter Properties. Where I will write them?

Thanks.

Code

<ListBox x:Name="listLocs" HorizontalAlignment="Left" Height="605" VerticalAlignment="Top" Width="250" SelectionChanged="listLocs_SelectionChanged" Margin="10,155,0,0" BorderBrush="#FF030042" BorderThickness="2" Foreground="#FF030042">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <StackPanel>
                    <Image Source="/Images/Pin2.png" Width="60"  Height="60" />
                </StackPanel>
                <StackPanel>
                    <StackPanel>
                        <TextBlock x:Name="txtName" Margin="10,0,0,0" Foreground="#FF030042"  FontSize="30" Text="{Binding Name}"/>
                    </StackPanel>
                    <StackPanel>
                        <TextBlock x:Name="txtDescription" Margin="10,0,0,0" Foreground="#FF030042" FontSize="20" Text="{Binding Description}"/>
                    </StackPanel>
                </StackPanel>
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

解决方案

You can do that in code behind altough in selectchanged event handler:

    private void listLocs_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        ListBoxItem myitem = listLocs.SelectedItem as ListBoxItem;
       SolidColorBrush brush =  new SolidColorBrush(Color.FromArgb(255,255,0,0));
       myitem.Background = brush;
    }
