wp7 复杂页面下去除ListBox虚拟化
最近做个项目,页面设计布局复杂,使用默认 ListBox 由于默认开启了虚拟化,会遇到暴力拖拉加载数据错位等问题,于是就想把虚拟化去除,代码如下
View Code
1 <ListBox Name="pleasureListBox">
2 <!-- 去除虚拟化-->
3 <ListBox.ItemsPanel>
4 <ItemsPanelTemplate>
5 <StackPanel>
6 </StackPanel>
7 </ItemsPanelTemplate>
8 </ListBox.ItemsPanel>
9
10 <ListBox.ItemTemplate>
11 <DataTemplate>
12 <StackPanel>
13 <!-- 头部模板-->
14 <Button Style="{StaticResource NoneStyleButtonStyle}">
15 <html:HtmlTextBlock LineHeight="36" Text="{Binding summary}" Foreground="#444444" TextWrapping="Wrap" FontSize="22" FontFamily="DengXian" MaxWidth="400" />
16 </Button>
17 <!--内容模板 -->
18 <ListBox Name="InfoItemListBox" ItemsSource="{Binding infoItemList}" Style="{StaticResource NotRollingListBoxStyle}">
19 <ListBox.ItemTemplate>
20 <DataTemplate>
21 <StackPanel>
22 <Grid >
23 <Grid HorizontalAlignment="Center">
24 <Image Name="BackgroundImage" Source="/MostInteresting;component/Images/LargerImageLoading1.png" Width="{Binding imgWidth}" MaxWidth="400" Stretch="None" VerticalAlignment="Center"/>
25 <Border BorderBrush="#bbbbbb" BorderThickness="3" Height="{Binding imgHeight}" MaxHeight="2010" MaxWidth="410" >
26 <Image Source="{Binding img}" ImageOpened="PleasureListImage_ImageOpened" DoubleTap="PleasureListImage_DoubleTap" Stretch="Uniform" Margin="5" MaxHeight="2000" MaxWidth="400"/>
27 </Border>
