c# - WPF ListView 与自定义类型和插入控件的绑定(bind)

Question

我正在制作聊天程序，并且我已经制作了API来连接服务器。

这是 API 的核心类

public partial class PengChat3ClientSock : IDisposable

嗯，PengChat3ClientSock 有一个 Rooms 属性。

public class Room
{
    public uint ID { get; private set; }

    public string Name { get; private set; }

    public string Master { get; internal set; }

    public short MaxConnectorNum { get; private set; }

    public bool IsNeedPassword { get; private set; }
}

这是一个 Rooms 属性

public Room[] Rooms { get; private set; }

现在是客户端，我有 ListView，它显示房间列表。

<ListView x:Name="listView_RoomList" Grid.Row="1" Grid.ColumnSpan="2">
</ListView>

我想像这样设计 ListView 。

RoomName Master MaxConnectorNum Password(If IsNeedPassword is true = Enable) EntryButton   DeleteButton(If Master is I = Enable)
Label    Label  Label           PasswordBox                                  Button        Button
Label    Label  Label           PasswordBox                                  Button        Button
Label    Label  Label           PasswordBox                                  Button        Button
Label    Label  Label           PasswordBox                                  Button        Button

顶部是标题。 我想插入这样的控件。

如果属性 Rooms 更改，我想自动更改此 ListView。

是不是太难了？但我认为这是可能的。

感谢您的回答。

如果我没有误解你的问题，试试这个

Room.cs

public class Room
{
    public uint ID { get;  set; }

    public string Name { get;  set; }

    public string Master { get;  set; }

    public short MaxConnectorNum { get;  set; }

    public bool IsNeedPassword { get;  set; }
}

xaml

    <Window.Resources>
    <Style TargetType="{x:Type Button}" x:Key="deleteButtonStyle">
        <Setter Property="IsEnabled" Value="False"></Setter>
        <Style.Triggers>
            <DataTrigger Binding="{Binding Master}" Value="I">
                <DataTrigger.Setters>
                    <Setter Property="IsEnabled" Value="True"></Setter>
                </DataTrigger.Setters>
            </DataTrigger>
        </Style.Triggers>
    </Style>
</Window.Resources>
<StackPanel>
    <ListView ItemsSource="{Binding Rooms}">
        <ListView.View>
            <GridView>
                <GridView.Columns>
                    <GridViewColumn Header="RoomName">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <Label Content="Label"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="Master">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <Label Content="Label"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="MaxConnectorNum">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <Label Content="Label"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="Password">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <PasswordBox IsEnabled="{Binding IsNeedPassword }" MinWidth="100"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="EntryButton">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <Button Content="Button"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="DeleteButton">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <Button Content="Button" Style="{StaticResource deleteButtonStyle}">
                                </Button>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>

            </GridView>
        </ListView.View>
    </ListView>
</StackPanel>

xaml.cs

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext=new ViewModel();
    }
}

ViewModel

    public class ViewModel
{
    public ObservableCollection<Room> Rooms { get; set; }

    public ViewModel()
    {
        Rooms = new ObservableCollection<Room>() 
        {
            new Room(){Master="I",IsNeedPassword=false},
            new Room(){Master="I",IsNeedPassword=true},
            new Room(){Master="j",IsNeedPassword=false},
            new Room(){Master="k",IsNeedPassword=true}
        };
    }
}

output
