WPF组合框多列 [英] WPF ComboBox Multiple Columns

问题描述

我只是想知道是否有一个wpf组合框控件可以包含多个列？

I am just wondering if there is a wpf combobox control that can contain multiple columns?

如果不是，我需要使用什么XAML来实现这一点？

And if not, what XAML I need to use to achieve this?

我只是寻找一个基本的两列组合框，如果可能，

I am just looking for a basic two column combobox if is possible,

感谢

请参阅多列组合框的链接，这是通过编辑combox和comboboxitem默认模板/样式实现的。 p>

Xaml代码：请查看ComboboxItem样式中注释的触发器已显示

 <Grid>
    <ComboBox Height="30" Margin="5" ItemsSource="{Binding}" HorizontalContentAlignment="Stretch">
        <ComboBox.ItemTemplate>
            <DataTemplate>
                <TextBlock Margin="2" Text="{Binding Name}"/>
            </DataTemplate>
        </ComboBox.ItemTemplate>
        <ComboBox.ItemContainerStyle>
            <Style TargetType="{x:Type ComboBoxItem}">                
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate>
                            <Grid x:Name="gd" TextElement.Foreground="Black">
                                <Grid.ColumnDefinitions>

                                    <ColumnDefinition/>
                                </Grid.ColumnDefinitions>
                                <TextBlock Margin="5" Grid.Column="0" Text="{Binding Name}"/>
                                <TextBlock Margin="5" Grid.Column="1" Text="{Binding State}"/>
                                <TextBlock Margin="5" Grid.Column="2" Text="{Binding Population}"/>
                            </Grid>
                            <ControlTemplate.Triggers>
                                <Trigger Property="ComboBoxItem.IsSelected" Value="True">
                                    <Setter TargetName="gd"  Property="Background" Value="Gray"></Setter>
                                    <Setter TargetName="gd"  Property="TextElement.Foreground" Value="White"></Setter>

                                </Trigger>

                                <!--IsHighlighted and IsMouseOver is showing same effect but IsHighlighted is used for showing logical focus( for understanding check using tab key)-->

                                <!--<Trigger Property="ComboBoxItem.IsHighlighted" Value="True">
                                    <Setter TargetName="gd"  Property="Background" Value="Yellow"></Setter>
                                    <Setter TargetName="gd"  Property="TextElement.Foreground" Value="Black"></Setter>
                                </Trigger>-->
                            </ControlTemplate.Triggers>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </ComboBox.ItemContainerStyle>
    </ComboBox>
</Grid>

c＃c​​ode

public partial class MainWindow : Window

    private ObservableCollection<City> cities = new ObservableCollection<City>();

    public MainWindow()
    {
        InitializeComponent();
        cities.Add(new City() { Name = "Mumbai", State = "Maharashtra", Population = 3000000 });
        cities.Add(new City() { Name = "Pune", State = "Maharashtra", Population = 7000000 });
        cities.Add(new City() { Name = "Nashik", State = "Maharashtra", Population = 65000 });
