C# 从treeview上的数据绑定treeview获取类属性单击

我遇到了一个问题，不管我在网上冲浪多少次，也不管我在网上的其他地方，我似乎都找不到一个正确的答案。我有一个树状视图，它绑定到

列表

，我的

类别

类如下

public class Category
{
    public string Name { get; set; }
    public dynamic SearchEngine { get; set; }
}

public class SearchEngine
{
    public virtual string IKey { get; set; }
    public virtual string IValue { get; set; }
    public virtual string icon { get; set; }
}

<TreeView.ItemTemplate>
    <HierarchicalDataTemplate ItemsSource="{Binding Path=ItemList}" ItemTemplate="{StaticResource ResourceKey=childrenDataTemplate}">
        <Border BorderThickness="0" Margin="5">
            <TextBlock Text="{Binding Path=Name}" />
        </Border>
        <HierarchicalDataTemplate.ItemContainerStyle>
            <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
                <Setter Property="FontWeight" Value="Normal"/>
                <Setter Property="Focusable" Value="True"/>
            </Style>
        </HierarchicalDataTemplate.ItemContainerStyle>
    </HierarchicalDataTemplate>
</TreeView.ItemTemplate>

<TreeView.ItemContainerStyle>
    <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
        <Setter Property="FontWeight" Value="Bold"/>
        <Setter Property="Focusable" Value="False"/>
    </Style>
</TreeView.ItemContainerStyle>

现在，TreeView正在使用一个自定义模板，如下所示：

<TreeView.ItemTemplate>
    <HierarchicalDataTemplate ItemsSource="{Binding Path=ItemList}" ItemTemplate="{StaticResource ResourceKey=childrenDataTemplate}">
        <Border BorderThickness="0" Margin="5">
            <TextBlock Text="{Binding Path=Name}" />
        </Border>
        <HierarchicalDataTemplate.ItemContainerStyle>
            <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
                <Setter Property="FontWeight" Value="Normal"/>
                <Setter Property="Focusable" Value="True"/>
            </Style>
        </HierarchicalDataTemplate.ItemContainerStyle>
    </HierarchicalDataTemplate>
</TreeView.ItemTemplate>

<TreeView.ItemContainerStyle>
    <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
        <Setter Property="FontWeight" Value="Bold"/>
        <Setter Property="Focusable" Value="False"/>
    </Style>
</TreeView.ItemContainerStyle>

<TreeView.ItemTemplate>
    <HierarchicalDataTemplate ItemsSource="{Binding Path=ItemList}" ItemTemplate="{StaticResource ResourceKey=childrenDataTemplate}">
        <Border BorderThickness="0" Margin="5">
            <TextBlock Text="{Binding Path=Name}" />
        </Border>
        <HierarchicalDataTemplate.ItemContainerStyle>
            <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
                <Setter Property="FontWeight" Value="Normal"/>
                <Setter Property="Focusable" Value="True"/>
            </Style>
        </HierarchicalDataTemplate.ItemContainerStyle>
    </HierarchicalDataTemplate>
</TreeView.ItemTemplate>

<TreeView.ItemContainerStyle>
    <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
        <Setter Property="FontWeight" Value="Bold"/>
        <Setter Property="Focusable" Value="False"/>
    </Style>
</TreeView.ItemContainerStyle>

<TreeView.ItemTemplate>
    <HierarchicalDataTemplate ItemsSource="{Binding Path=ItemList}" ItemTemplate="{StaticResource ResourceKey=childrenDataTemplate}">
        <Border BorderThickness="0" Margin="5">
            <TextBlock Text="{Binding Path=Name}" />
        </Border>
        <HierarchicalDataTemplate.ItemContainerStyle>
            <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
                <Setter Property="FontWeight" Value="Normal"/>
                <Setter Property="Focusable" Value="True"/>
            </Style>
        </HierarchicalDataTemplate.ItemContainerStyle>
    </HierarchicalDataTemplate>
</TreeView.ItemTemplate>

<TreeView.ItemContainerStyle>
    <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
        <Setter Property="FontWeight" Value="Bold"/>
        <Setter Property="Focusable" Value="False"/>
    </Style>
</TreeView.ItemContainerStyle>

正如您所看到的，我已经在我的TreeView对象中绑定了

TreeView项，并且我能够在更改选择时提醒messagebox。我想在选择时获取
IValue
，并将其传递给另一个函数进行处理。我查看了SelectedItem，但似乎找不到一种方法来访问底层数据源

<TreeView.ItemTemplate>
    <HierarchicalDataTemplate ItemsSource="{Binding Path=ItemList}" ItemTemplate="{StaticResource ResourceKey=childrenDataTemplate}">
        <Border BorderThickness="0" Margin="5">
            <TextBlock Text="{Binding Path=Name}" />
        </Border>
        <HierarchicalDataTemplate.ItemContainerStyle>
            <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
                <Setter Property="FontWeight" Value="Normal"/>
                <Setter Property="Focusable" Value="True"/>
            </Style>
        </HierarchicalDataTemplate.ItemContainerStyle>
    </HierarchicalDataTemplate>
</TreeView.ItemTemplate>

<TreeView.ItemContainerStyle>
    <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
        <Setter Property="FontWeight" Value="Bold"/>
        <Setter Property="Focusable" Value="False"/>
    </Style>
</TreeView.ItemContainerStyle>

有什么建议吗？谢谢。
你试过这个吗：

<TreeView.ItemTemplate>
    <HierarchicalDataTemplate ItemsSource="{Binding Path=ItemList}" ItemTemplate="{StaticResource ResourceKey=childrenDataTemplate}">
        <Border BorderThickness="0" Margin="5">
            <TextBlock Text="{Binding Path=Name}" />
        </Border>
        <HierarchicalDataTemplate.ItemContainerStyle>
            <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
                <Setter Property="FontWeight" Value="Normal"/>
                <Setter Property="Focusable" Value="True"/>
            </Style>
        </HierarchicalDataTemplate.ItemContainerStyle>
    </HierarchicalDataTemplate>
</TreeView.ItemTemplate>

<TreeView.ItemContainerStyle>
    <Style TargetType="TreeViewItem" BasedOn="{StaticResource TreeViewItem}">
        <Setter Property="FontWeight" Value="Bold"/>
        <Setter Property="Focusable" Value="False"/>
    </Style>
</TreeView.ItemContainerStyle>

void HandleSelected(object sender, RoutedEventArgs e)
    {
        var tvi = e.Source as TreeViewItem;
        var category = tvi.DataContext as Category;
        ...
    }

铸造怎么样？如果您知道基础项数据的类型，只需将其转换为该类型即可。@KingKing Yeah证明有效，谢谢。虽然我不得不使用
e.OriginalSource
，但这是有效的，我接受作为答案，谢谢。
