【问题描述】:
我想水平显示项目列表并能够从该项目列表中进行选择 - 我尝试使用列表视图并根据堆栈上的一些帖子更改项目模板,我有这个:
<ListView Height="Auto" HorizontalAlignment="Left" Margin="24,0,0,0" Name="MachinesListView" VerticalAlignment="Top" Width="1455" Background="#FFF0F0F0" ItemsSource="{Binding Machines}" BorderBrush="#FFF0F0F0" Grid.ColumnSpan="2" Grid.Row="2" SelectionChanged="MachinesListView_SelectionChanged">
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Width="{Binding (FrameworkElement.ActualWidth),
RelativeSource={RelativeSource AncestorType=ScrollContentPresenter}}"
ItemWidth="{Binding (ListView.View).ItemWidth,
RelativeSource={RelativeSource AncestorType=ListView}}"
MinWidth="{Binding ItemWidth, RelativeSource={RelativeSource Self}}"
ItemHeight="{Binding (ListView.View).ItemHeight,
RelativeSource={RelativeSource AncestorType=ListView}}" />
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="Height" Value="175"/>
<Setter Property="Width" Value="275"/>
<Setter Property="Margin" Value="5,5,0,0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border BorderBrush="Gray" BorderThickness="2" CornerRadius="10">
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Machine.MachineId}" TextAlignment="Center" Width="Auto" Foreground="#FF639A70" FontSize="19"/>
<TextBlock Text="{Binding Machine.Name}" TextAlignment="Center" Width="Auto" Foreground="Gray" FontSize="15" />
<Image Source="/URM;component/Images/slot_machine-512.png" Height="60" Width="60" />
<TextBlock Text="{Binding Machine.Description}" TextAlignment="Center" Width="Auto" Foreground="Gray" FontSize="15" Margin="0, 5, 0, 0"/>
<TextBlock TextAlignment="Center" Width="Auto" Foreground="Gray" FontSize="15" Margin="0, 5, 0, 0">
<Run Text ="Actual: "/>
<Run Text ="{Binding Actual, StringFormat=' {0:c}'}"/>
</TextBlock>
<TextBlock TextAlignment="Center" Width="Auto" Foreground="Gray" FontSize="15" Margin="0, 5, 0, 0">
<Run Text ="OverShort: "/>
<Run Text ="{Binding OverShort, StringFormat=' {0:c}'}"/>
</TextBlock>
</StackPanel>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListView.ItemContainerStyle>
</ListView>
这很好...我从中获得了我想要的整体外观,但仅选择第一项会导致 selectionchanged 事件触发...
我曾考虑将项目实现为按钮,但我认为可能有更合适的方法来处理这个问题。
【问题讨论】:
-
有什么问题?您无法从列表中选择任何项目?它只选择第一个可用的项目?
-
我只能选择第一项。或者我应该说 selectionchanged 事件仅在您选择第一项时触发。
