问题描述

我正在使用WPF Windows应用程序.我正在使用ItemsControl显示收藏夹列表.为此，我发现ItemsControl中没有SelectedItem属性.然后，如何从ItemsControl获取选定的项目.还有如何显示ItemsControl的标题.

I am working on WPF Windows Application. I'm using ItemsControl to show collection list. Working on this I found there is no SelectedItem property in ItemsControl. Then how can I get the Selected Item from the ItemsControl. And also How can I display the Headers of ItemsControl.

<ItemsControl ItemsSource="{Binding CustomSalesProducts, Mode=TwoWay}">
        <ItemsControl.Template>
            <ControlTemplate TargetType="ItemsControl">
                <Border>
                    <ScrollViewer VerticalScrollBarVisibility="Auto">
                        <ItemsPresenter/>
                    </ScrollViewer>
                </Border>
            </ControlTemplate>
        </ItemsControl.Template>
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <VirtualizingStackPanel CanHorizontallyScroll="True" CanVerticallyScroll="True" Orientation="Vertical"/>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Grid x:Name="SalesGrid" Background="White">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="Auto"/>
                        <ColumnDefinition Width="Auto"/>
                        <ColumnDefinition Width="Auto"/>
                        <ColumnDefinition Width="Auto"/>
                        <ColumnDefinition Width="Auto"/>
                        <ColumnDefinition Width="Auto"/>
                    </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                    </Grid.RowDefinitions>
                    <controls:HeaderedContentControl Header="{Binding ProductName, Mode=TwoWay}" Margin="{DynamicResource Margin4}" Style="{DynamicResource HeaderedContentControlStyle}" HorizontalContentAlignment="Right">
                    </controls:HeaderedContentControl>
                    <TextBox Text="{Binding OrderQty, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Grid.Row="1" Margin="{StaticResource Margin4}" Style="{DynamicResource MiniTextBoxStyle}" ToolTip="Quantity" />
                    <TextBlock Text="{Binding UnitSalePrice, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Grid.Column="1" Grid.Row="1" Margin="{StaticResource Margin4}" ToolTip="Price"/>
                    <TextBox Text="{Binding Discount, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Grid.Column="2" Grid.Row="1" Margin="{StaticResource Margin4}" Style="{DynamicResource MiniTextBoxStyle}" ToolTip="Discount"/>
                    <TextBlock Text="{Binding TaxAmount, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Grid.Column="3" Grid.Row="1" Margin="{StaticResource Margin4}" ToolTip="Tax Amount"/>
                    <TextBlock Text="{Binding LineTotal, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Grid.Column="4" Grid.Row="1" Margin="{StaticResource Margin4}" ToolTip="Total"/>

                </Grid>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>

谢谢

推荐答案

我发现使用Header有HeaderdItemsControl.有了这个我可以添加标题，而且它是不可重复的.但这有一个问题，就是如果我们定义了自动大小，则必须为标头及其项目定义静态大小，然后headeredItemsControl的用户界面并不完美，因此我们必须给出其静态大小.

I found that for using headers there is HeaderdItemsControl. With this I can add headers and also it is not repeatable. But problem with this is that we have to define static size for header and its item if we define auto size then the UI of headeredItemsControl is not perfect so we have to give its static size.
