两种方法创建WPF目录树TreeView和GridView数据绑定_c#wpf树绑定datagrid

 效果

定义数据结构

public class DirectoryInformation
{
    public DirectoryInfo Info { get; set; }

    public IEnumerable<FileInfo> Files
    {
        get
        {
            return Info.GetFiles();
        }
    }

    public IEnumerable<DirectoryInformation> Directories
    {
        get
        {
            try
            {
                return from di in Info.GetDirectories() select new DirectoryInformation { Info = di };
            }
            catch (Exception)
            {
                return null;
            }
        }
    }
}

方法一，在CS代码中自动生成列，并绑定数据

UI界面代码

<Grid Grid.Row="1" x:Name="leftPanel">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="30*"/>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition Width="70*"/>
    </Grid.ColumnDefinitions>
    <TreeView Grid.Column="0" x:Name="leftDirectoryTree">
        <TreeView.Resources>
            <HierarchicalDataTemplate DataType="{x:Type fileio:DirectoryInformation}" ItemsSource="{Binding Directories}">
                <StackPanel Orientation="Horizontal">
                    <TextBlock Text="{Binding Info.Name}"/>
                </StackPanel>
            </HierarchicalDataTemplate>
        </TreeView.Resources>
    </TreeView>
    <GridSplitter Grid.Column="1" Width="2" HorizontalAlignment="Center" VerticalAlignment="Stretch"/>
    <ListView Grid.Column="2" ItemsSource="{Binding ElementName=leftDirectoryTree, Path=SelectedItem.Files}">
        <ListView.View>
            <GridView x:Name="leftDetailView">
            </GridView>
        </ListView.View>
    </ListView>
</Grid>

CS代码

public MainWindow()
{
    InitializeComponent();
    LoadFilePanel();
}

private void LoadFilePanel()
{
    LoadDirectoryTree();
    LoadDetailView();
}

private void LoadDirectoryTree()
{
    var drives = new ObservableCollection<DirectoryInformation>();

    foreach (var drive in DriveInfo.GetDrives())
    {
        drives.Add(
            new DirectoryInformation
            {
                Info = new DirectoryInfo(drive.RootDirectory.FullName)
            }
        );
    }

    leftDirectoryTree.ItemsSource = drives;
}

private void LoadDetailView()
{
    List<string> requiredProperties = new List<string>
    {
        "Name", "Length", "IsReadOnly", "LastWriteTime"
    };
 
    foreach (string name in requiredProperties)
    {
        GridViewColumn colmun = new GridViewColumn { Header = name };
        Binding binding = new Binding(name);
        colmun.DisplayMemberBinding = binding;
        leftDetailView.Columns.Add(colmun);
    }
}

方法二，修改以上代码，在XAML中设置固定列，并绑定数据

<ListView Grid.Column="2" ItemsSource="{Binding ElementName=leftDirectoryTree, Path=SelectedItem.Files}">
    <ListView.View>
        <GridView x:Name="leftDetailView">
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
            <GridViewColumn Header="Length" DisplayMemberBinding="{Binding Length}"/>
            <GridViewColumn Header="LastWriteTime" DisplayMemberBinding="{Binding LastWriteTime}"/>
        </GridView>
    </ListView.View>
</ListView>

CS代码，只需要加载目录树即可

private void LoadFilePanel()
{
    LoadDirectoryTree();
} 

 

另外，设置DataTemplate可以自定义每个单元格的显示效果，具体可以再网上搜索一下。

List

<DataTemplate>

<StackPanel Orientation="Horizontal" x:Name="richNameContainer">

<Image Source="{Binding FullName, Converter={StaticResource pathToSmallIcon}}"/>

<Grid>

<TextBlock x:Name="fileName" Margin="3,3" Text="{Binding Name}"/>

</Grid>

</StackPanel>

</DataTemplate>

Tile

<DataTemplate x:Key="tileViewTemplate">

<StackPanel Height="110" Width="80">

<Image Source="{Binding FullName, Converter={StaticResource pathToLargeIcon}}"/>

<Grid HorizontalAlignment="Center">

<TextBlock x:Name="fileName" Text="{Binding Name}" TextWrapping="Wrap"/>

</Grid>

</StackPanel>

</DataTemplate>
