ListBox 内的 ListBox 和 selectedItem/Events [英] ListBox inside ListBox and selectedItem / Events

问题描述

我现在被困在这个问题上有一段时间了，所以我想问问这里的专家.

I have now been stuck at this for some time so I though to ask the experts here.

首先是 XAML:

<ListBox Grid.Column="0" Tap="Some_Tap" SelectionChanged="Some_SelectionChanged">

                    <ListBox.ItemTemplate>
                        <DataTemplate>

                            <!-- the panel which covers a complete list item -->
                            <StackPanel Orientation="Vertical">

                                <!-- start and end time for the travel route-->
                                <Grid HorizontalAlignment="Center">
                                    <Grid.ColumnDefinitions>
                                        <ColumnDefinition Width="100"/>
                                        <ColumnDefinition Width="100"/>
                                        <ColumnDefinition Width="100"/>
                                        <ColumnDefinition Width="100"/>
                                    </Grid.ColumnDefinitions>

                                    <Grid.RowDefinitions>
                                        <RowDefinition/>
                                        <RowDefinition/>
                                    </Grid.RowDefinitions>


                                    <!-- some textblock items, removed to keep this simple -->
                                </Grid>

                                <!-- list box for images -->
                                <ListBox ScrollViewer.HorizontalScrollBarVisibility="Disabled"  ScrollViewer.VerticalScrollBarVisibility="Disabled" ItemsSource="{Binding Thumbs}" HorizontalAlignment="Center" Margin="0,10,0,50">
                                    <ListBox.ItemsPanel>
                                        <ItemsPanelTemplate>
                                            <StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" />
                                        </ItemsPanelTemplate>
                                    </ListBox.ItemsPanel>

                                    <ListBox.ItemTemplate>
                                        <DataTemplate>
                                            <StackPanel Orientation="Vertical" HorizontalAlignment="Center">

                                                <Image Source="{Binding Image}" HorizontalAlignment="Center"/>
                                                <TextBlock Text="{Binding Text}" HorizontalAlignment="Center" FontWeight="{Binding FontWeightForText}">
                                                    <TextBlock.Foreground>
                                                        <SolidColorBrush Color="{StaticResource PhoneForegroundColor}"/>
                                                    </TextBlock.Foreground>
                                                </TextBlock>

                                            </StackPanel>
                                        </DataTemplate>
                                    </ListBox.ItemTemplate>

                                </ListBox>

                            </StackPanel>
                        </DataTemplate>

                    </ListBox.ItemTemplate>

                </ListBox>

正如您从 XAML 中看到的，我在另一个 ListBox 的数据模板内有一个 ListBox.我有 Tap &SelectionChanged 事件已连接.

So as you can see from the XAML I have a ListBox inside the data template of another ListBox. I have Tap & SelectionChanged events wired.

问题:

1. 我无法点击内部列表框覆盖的区域，外部列表框的点击或选择更改事件不会为外部列表框触发.

1. I can't click on the area covered by the inner list box, the tap or selection changed events for the outer list box are not fired for the outerlistbox.

我也可以为内部列表框连接点击和选择更改事件，但是我怎么知道这个内部列表框属于外部列表框中的哪个项目，selectedindex.

I could wire tap and selection changed events for the inner listbox as well, but then how would I know which item in the outerlistbox this innerlistbox belongs to, selectedindex.

帮助??

推荐答案

如果不需要列表中的项目选择，请使用 ItemsControl 代替(这种情况下的内部列表)

If you don't need items selection in the list, use ItemsControl instead (for inner list in this situation)
