如何在每个组之前的分组项目页面中插入图像列表? [英] How to insert an image list in the grouped items page befor each group?

问题描述

我目前正在使用 XAML 和 C# 开发 Windows 8 应用程序.我开发了动态生成数据组的分组项目页面.我有一个社交媒体图标列表，我需要将它们放在每个组标题旁边，但要在左侧对齐，如屏幕截图所示！

I am currently developing a windows 8 application using XAML and C#. I developed the grouped items page that generates data groups dynamically. I have a list of social media icons that I need to put next to each group title but aligned on the left as shown in the screen shot!

当我在 XAML 代码中添加列表时，它会在第一组的开头生成！我怎样才能为每个组拥有它?有任何想法吗?如果有人能给我提供非常有用的代码.

When I add the list in the XAML Code, it is getting generated at the beginning of the first group! How can I have it for each group? any ideas? if anyone can provide me with the code that would be very helpful.

推荐答案

在页面资源部分定义GroupItemStyle如下:

Define GroupItemStyle in page resources section as follows:

<Style x:Key="GroupItemStyle1" TargetType="GroupItem">
            <Setter Property="IsTabStop" Value="False"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="GroupItem">
                        <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
                            <Grid>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="431*"/>
                                    <ColumnDefinition Width="429*"/>
                                </Grid.ColumnDefinitions>
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="Auto"/>
                                    <RowDefinition Height="*"/>
                                </Grid.RowDefinitions>
                                <ContentControl x:Name="HeaderContent" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" ContentTemplateSelector="{TemplateBinding ContentTemplateSelector}" Content="{TemplateBinding Content}" IsTabStop="False" Margin="{TemplateBinding Padding}" TabIndex="0" Grid.Column="1"/>
                                <ItemsControl x:Name="ItemsControl" IsTabStop="False" ItemsSource="{Binding GroupItems}" Grid.Row="1" TabIndex="1" TabNavigation="Once" Grid.Column="1">
                                    <ItemsControl.ItemContainerTransitions>
                                        <TransitionCollection>
                                            <AddDeleteThemeTransition/>
                                            <ContentThemeTransition/>
                                            <ReorderThemeTransition/>
                                            <EntranceThemeTransition IsStaggeringEnabled="False"/>
                                        </TransitionCollection>
                                    </ItemsControl.ItemContainerTransitions>
                                </ItemsControl>
                                <!-- ***** Put your social icon list here **** Start-->
                                <Button Content="Button" HorizontalAlignment="Left" Margin="0,194,0,0" Grid.Row="1" VerticalAlignment="Top"/>
                                <!-- ***** Put your social icon list here **** End -->
                            </Grid>
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

将此样式应用于 GridView:

Apply this style to GridView as:

<!-- Horizontal scrolling grid used in most view states -->
        <GridView
            x:Name="itemGridView"
            AutomationProperties.AutomationId="ItemGridView"
            AutomationProperties.Name="Grouped Items"
            Grid.RowSpan="2"
            Padding="116,137,40,46"
            ItemsSource="{Binding Source={StaticResource groupedItemsViewSource}}"
            ItemTemplate="{StaticResource Standard250x250ItemTemplate}"
            SelectionMode="None"
            IsSwipeEnabled="false"
            IsItemClickEnabled="True"
            ItemClick="ItemView_ItemClick">

            <GridView.ItemsPanel>
                <ItemsPanelTemplate>
                    <VirtualizingStackPanel Orientation="Horizontal"/>
                </ItemsPanelTemplate>
            </GridView.ItemsPanel>
            <GridView.GroupStyle>
                <GroupStyle ContainerStyle="{StaticResource GroupItemStyle1}">
                    <GroupStyle.HeaderTemplate>
                        <DataTemplate>
                            <Grid Margin="1,0,0,6">
                            .......
                  </GroupStyle>
        </GridView.GroupStyle>
    </GridView>

您将在此处看到每个组之前的示例按钮 -

You will see the sample button before each group here -

更新:

使用以下组样式:例如:

Use following group styles: for example:

  <Style x:Key="GroupItemStyle3" TargetType="GroupItem">
        <Setter Property="IsTabStop" Value="False"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="GroupItem">
                    <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
                        <Grid>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="431*"/>
                                <ColumnDefinition Width="429*"/>
                            </Grid.ColumnDefinitions>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="Auto"/>
                                <RowDefinition Height="*"/>
                            </Grid.RowDefinitions>
                            <ContentControl x:Name="HeaderContent" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" ContentTemplateSelector="{TemplateBinding ContentTemplateSelector}" Content="{TemplateBinding Content}" IsTabStop="False" Margin="{TemplateBinding Padding}" TabIndex="0" Grid.ColumnSpan="2"/>
                            <ItemsControl x:Name="ItemsControl" IsTabStop="False" ItemsSource="{Binding GroupItems}" Grid.Row="1" TabIndex="1" TabNavigation="Once" Grid.Column="1">
                                <ItemsControl.ItemContainerTransitions>
                                    <TransitionCollection>
                                        <AddDeleteThemeTransition/>
                                        <ContentThemeTransition/>
                                        <ReorderThemeTransition/>
                                        <EntranceThemeTransition IsStaggeringEnabled="False"/>
                                    </TransitionCollection>
                                </ItemsControl.ItemContainerTransitions>
                            </ItemsControl>


                            <StackPanel Background="Red" Grid.Row="1">
        <!-- ***** Put your social icon list here **** Start-->                 
            <Button Content="Button" HorizontalAlignment="Left" Margin="0" VerticalAlignment="Top"/>
                            <!-- ***** Put your social icon list here **** End -->
                            </StackPanel>

                        </Grid>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

这会给你:

这个会:

 <Style x:Key="GroupItemStyle2" TargetType="GroupItem">
            <Setter Property="IsTabStop" Value="False"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="GroupItem">
                        <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
                            <Grid>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="431*"/>
                                    <ColumnDefinition Width="429*"/>
                                </Grid.ColumnDefinitions>
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="Auto"/>
                                    <RowDefinition Height="*"/>
                                </Grid.RowDefinitions>
                                <ContentControl x:Name="HeaderContent" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" ContentTemplateSelector="{TemplateBinding ContentTemplateSelector}" Content="{TemplateBinding Content}" IsTabStop="False" Margin="{TemplateBinding Padding}" TabIndex="0" Grid.Column="1"/>
                                <ItemsControl x:Name="ItemsControl" IsTabStop="False" ItemsSource="{Binding GroupItems}" Grid.Row="1" TabIndex="1" TabNavigation="Once" Grid.Column="1">
                                    <ItemsControl.ItemContainerTransitions>
                                        <TransitionCollection>
                                            <AddDeleteThemeTransition/>
                                            <ContentThemeTransition/>
                                            <ReorderThemeTransition/>
                                            <EntranceThemeTransition IsStaggeringEnabled="False"/>
                                        </TransitionCollection>
                                    </ItemsControl.ItemContainerTransitions>
                                </ItemsControl>


                                <StackPanel  Grid.RowSpan="2" Background="Red">
                                    <!-- ***** Put your social icon list here **** Start-->
                                    <Button Content="Button" HorizontalAlignment="Left" Margin="0" VerticalAlignment="Top"/>
                                    <!-- ***** Put your social icon list here **** End -->
                                </StackPanel>

                            </Grid>
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
