Question

我正在制作聊天程序，我已经建立了连接服务器的API。

这是API的核心类

public partial class PengChat3ClientSock : IDisposable

好吧，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; }
}

这是房产

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

现在是客户端，我有ListView显示房间列表。

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

我想设计这样的列表视图。

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。我想插入像这样的控件。

如果属性Rooms发生了变化，我想自动更改此ListView。

太难了吗？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"/>

                        </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>

                                <Button Content="Button" Style="{StaticResource deleteButtonStyle}">
                                </Button>

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

xaml.cs

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

视图模型

    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}
        };
    }
}
