我正在使用具有自定义 ItemTemplate 样式的列表框。它基本上为列表框中的每个项目附加一个按钮。我想在没有按钮的情况下显示列表框中的最后一项。我怎样才能完成它?
.xaml 文件代码如下。
<!-- ListBox to display recordings -->
<ListBox Name="myListBox" Grid.Row="0"
HorizontalAlignment="Left" Width="470"
ScrollViewer.VerticalScrollBarVisibility="Visible"
ScrollViewer.ManipulationMode="System"
SelectionChanged="OnMemosListBoxSelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Button Grid.Column="0"
Grid.Row="0"
Grid.RowSpan="3"
Padding="0"
HorizontalAlignment="Left"
VerticalAlignment="top"
Height="80"
Width="80"
Tag="{Binding BindsDirectlyToSource=True}"
Click="OnDeleteButtonClick">
<Button.Content>
<Image Source="/images/delete.png" Margin="0" Width="50" Height="50" />
</Button.Content>
</Button>
<TextBlock Grid.Column="1"
FontSize="{StaticResource PhoneFontSizeMediumLarge}"
Grid.Row="0"
Text="{Binding fileName}"
VerticalAlignment="Center"/>
<StackPanel Grid.Column="1" Margin="0,0,0,17"
Grid.Row="1" Height="50"
Orientation="Horizontal"
VerticalAlignment="Top">
<TextBlock FontSize="{StaticResource PhoneFontSizeNormal}" Text="Recorded on " />
<TextBlock FontSize="{StaticResource PhoneFontSizeNormal}" Text="{Binding crDate}" />
<TextBlock Text=" Duration " />
<TextBlock FontSize="{StaticResource PhoneFontSizeNormal}" Text="{Binding duration}" />
</StackPanel>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
