使用自定义模板在 Silverlight 列表框中自动滚动
我有带有自定义模板的列表框,如何以编程方式将其向下滚动到底部?
Silverlight 列表框中的自动滚动 描述了滚动到底部的方法列表框。不幸的是,此方法不适用于具有自定义样式模板的 ListBox。
有人成功地用自定义样式滚动列表框吗?
问题代码:
<Grid.Resources>
<Style x:Key="HorizontalWrapListBox" TargetType="ListBox">
<Style.Setters>
<Setter Property="ItemsPanel">
<Setter.Value>
<ItemsPanelTemplate>
<toolkit:WrapPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBox">
<ScrollViewer>
<ItemsPresenter />
</ScrollViewer>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style.Setters>
</Style>
</Grid.Resources>
<ListBox x:Name="MyListBox" Margin="0,0,-12,0" ItemsSource="{Binding Items}"
Style="{StaticResource HorizontalWrapListBox}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,0,0,17" Width="432" Height="78">
<TextBlock Text="{Binding LineOne}" TextWrapping="Wrap"
Style="{StaticResource PhoneTextExtraLargeStyle}"/>
<TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap"
Margin="12,-6,12,0"
Style="{StaticResource PhoneTextSubtleStyle}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

您需要保持模板部件的正确命名,这才可以开始工作。 ScrollViewer 应命名为 x:Name="ScrollViewer"。检查
You need to keep correct naming of your template parts and this could just start working. The ScrollViewer should be named x:Name="ScrollViewer". Check
