绑定任意XML文档WPF的TreeView [英] Bind Any XML document to WPF TreeView

问题描述

我想使用的TypeConverter任何XML文档绑定到WPF树视图。

I would like to bind any XML document to WPF TreeView using TypeConverter.

我原来的解决方案是使用递归，但是当文档很大UI在很大程度上绑起来

My original solution was to use recursion, but when document is large UI is heavily tied up.

以下有关的TypeConverter但对于特定的节点/元素组合联系洽谈：

Following link talks about TypeConverter but for particular node/element combination: http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/edd843b7-b378-4c2d-926f-c053dbd7b340

如果不知道什么外观的XML文档样的呢？由于这是仅用于显示我不那么在意在这一点上我只想XML绑定到树视图功能。

What if not known what XML document looks like? Since this is for display purposes only I don't care much about functionality at this point I just want to bind XML to a TreeView.

推荐答案

它适用于其他节点类型有一些简单的修改。首先，HierarchicalDataTemplate.ItemsSource装订的XPath必须改变，以子::节点（）|属性:: *，以允许任何子节点和任何属性。然后，对其他NodeTypes添加DataTriggers。下面的例子为我工作。我添加图标各种NodeTypes注意，你可能想将其删除：

It works for other node types with a few simple modifications. First, HierarchicalDataTemplate.ItemsSource Binding XPath must be changed to "child::node()|attribute::*" to allow any child node and any attribute. Then, add DataTriggers for other NodeTypes. The example below worked for me. NOTE that i added icons for various NodeTypes, you might want to remove them:

        <HierarchicalDataTemplate x:Key="NodeTemplate">
        <StackPanel Orientation="Horizontal">
        <Image x:Name="icon" VerticalAlignment="Center" Margin="1,1,4,1"/>
        <TextBlock x:Name="name" Text="" />
        <TextBlock x:Name="inter" Text="" />
        <TextBlock x:Name="value" Text="" />
        </StackPanel>
        <HierarchicalDataTemplate.ItemsSource>
            <Binding XPath="child::node()|attribute::*" />
        </HierarchicalDataTemplate.ItemsSource>
        <HierarchicalDataTemplate.Triggers>
            <DataTrigger Binding="{Binding Path=NodeType}" Value="Element">
                <Setter TargetName="icon" Property="Source" Value="icons/element.png"></Setter>
                <Setter TargetName="name" Property="Text" Value="{Binding Path=Name}"></Setter>
            </DataTrigger>
            <DataTrigger Binding="{Binding Path=NodeType}" Value="Text">
                <Setter TargetName="icon" Property="Source" Value="icons/text.png"></Setter>
                <Setter TargetName="value" Property="Text" Value="{Binding Path=Value}"></Setter>
            </DataTrigger>
            <DataTrigger Binding="{Binding Path=NodeType}" Value="Attribute">
                <Setter TargetName="icon" Property="Source" Value="icons/attribute.png"></Setter>
                <Setter TargetName="name" Property="Text" Value="{Binding Path=Name}"></Setter>
                <Setter TargetName="inter" Property="Text" Value=": "></Setter>
                <Setter TargetName="value" Property="Text" Value="{Binding Path=Value}"></Setter>
            </DataTrigger>
            <DataTrigger Binding="{Binding Path=NodeType}" Value="CDATA">
                <Setter TargetName="icon" Property="Source" Value="icons/cdata.png"></Setter>
                <Setter TargetName="value" Property="Text" Value="{Binding Path=Value}"></Setter>
            </DataTrigger>
            <DataTrigger Binding="{Binding Path=NodeType}" Value="Comment">
                <Setter TargetName="icon" Property="Source" Value="icons/comment.png"></Setter>
                <Setter TargetName="value" Property="Text" Value="{Binding Path=Value}"></Setter>
            </DataTrigger>
            <DataTrigger Binding="{Binding Path=NodeType}" Value="ProcessingInstruction">
                <Setter TargetName="icon" Property="Source" Value="icons/pi.png"></Setter>
                <Setter TargetName="value" Property="Text" Value="{Binding Path=Value}"></Setter>
            </DataTrigger>
        </HierarchicalDataTemplate.Triggers>
    </HierarchicalDataTemplate>
