WPF树视图绑定 [英] WPF tree view binding

问题描述

我想在网格中显示图像文件.它们将从树视图中选择为名称，并且树视图与xml文件绑定，我正在显示图像的名称，并且我想使用我在xml中定义的ref属性，即图像的路径.
请任何人理解我的问题，并为我提供解决方案.

xml是:

 <  图书馆 > ; 
    <  类别    ="  全部" 名称  全部" > 
            <  图书    ="  故事" 名称  和尚"     ref   =   C:\ Users \ Public \ Pictures \ Sample   Pictures \ page2/  > 
        <  图书    ="  故事" 名称  照片"     ref   =   C:\ Users \ Public \ Pictures \ Sample   Pictures \ page3/ ">> ; 
            <  图书    ="  恐怖" 名称   Better You"    ref   =   C:\ Users \ Public \ Pictures \ Sample   Pictures \ page4/  > 
        <  图书    ="  恐怖" 名称   Dracula"    ref   =   C:\ Users \ Public \ Pictures \ Sample   Pictures \ page5/ ">> ; 
    <  /类别 > 

<  /库 >   pre> 



我将树形视图用作:

 <   Window.Resources  > 
        <   HierarchicalDataTemplate     ="   {Binding Path = Elements}"    x:Key   ="  <   TreeViewItem     ="   {Binding Path = Attribute [Name] .Value}" / > 
        <  /HierarchicalDataTemplate  > 
        <！-  < XmlDataProvider x:Key ="XMLdata"源="C:\ Users \ SBS \ Desktop \ wizaed.xml"></XmlDataProvider>  ->  
    <  /Window.Resources  >  
 



 < TreeView  MouseUp ="_ treeView_MouseUp" Cursor ="Hand" x:Name ="_ treeView" Width ="160" Background =透明" Margin ="0， 10 ，10" BorderBrush ="Transparent" BorderThickness ="0 "
                              ItemsSource ="{.元素}"
                              ItemTemplate ="{" /> 
 





后面的代码是:



 XDocument XDoc = XDocument.Parse(File.ReadAllText(@"C:\ Users \ Public \ Mylibrary.xml")); 

            _treeView.DataContext = XDoc; 
解决方案
 
您是否要实现这样的目标? <   Window.Resources  > 
   <   XmlDataProvider     ="   XMLdata" 源   C :\ DirectoryStructure \ Library.xml" / > 
   <   HierarchicalDataTemplate     ="  库"  ItemsSource    {绑定XPath = Elements}" <   TreeViewItem  > 
         <   TreeViewItem.Header  > 
           <   StackPanel     ="  <  图片    ="   {Binding XPath = @ ref}"   / > 
             <   TextBlock     ="   {Binding XPath = @ Name}"   / > 
           <  /StackPanel  > 
         <  /TreeViewItem.Header  > 
      <  /TreeViewItem  > 
   <  /HierarchicalDataTemplate  > 
<  /Window.Resources  > 
<  网格 > 
<   TreeView     ="  手"  x:Name    _ treeView " 宽度   160" 背景  透明" 保证金  ="   BorderBrush   透明"  BorderThickness    0" 
                                                ItemsSource   ="  
                                                ItemTemplate   ="  / <Library>
    <Category CategoryName="All" Name="All">
            <Book CategoryName="Story" Name="The Monk" ref=C:\Users\Public\Pictures\Sample Pictures\page2/>
        <Book CategoryName="Story" Name="Photos" ref=C:\Users\Public\Pictures\Sample Pictures\page3/>
            <Book CategoryName="Horror" Name="Better You" ref=C:\Users\Public\Pictures\Sample Pictures\page4/>
        <Book CategoryName="Horror" Name="Dracula" ref=C:\Users\Public\Pictures\Sample Pictures\page5/>
    </Category>

</Library>

and i am using the tree view as:

<Window.Resources>
        <HierarchicalDataTemplate ItemsSource="{Binding Path=Elements}" x:Key="Library">
            <TreeViewItem Header="{Binding Path=Attribute[Name].Value}"/>
        </HierarchicalDataTemplate>
        <!--<XmlDataProvider x:Key="XMLdata" Source="C:\Users\SBS\Desktop\wizaed.xml" ></XmlDataProvider>-->
    </Window.Resources>

<TreeView MouseUp="_treeView_MouseUp" Cursor="Hand" x:Name="_treeView" Width="160" Background="Transparent" Margin="0,10,10,10" BorderBrush="Transparent" BorderThickness="0"
                              ItemsSource="{Binding Path=Root.Elements}"
                              ItemTemplate="{StaticResource ResourceKey=Library}" />

and the code behind is:

XDocument XDoc = XDocument.Parse(File.ReadAllText(@"C:\Users\Public\Mylibrary.xml"));
_treeView.DataContext = XDoc;

解决方案

Are you trying to achieve something like this?

<Window.Resources>
   <XmlDataProvider x:Key="XMLdata" Source="C:\DirectoryStructure\Library.xml" />
   <HierarchicalDataTemplate x:Key="Library" ItemsSource="{Binding XPath=Elements}">
      <TreeViewItem>
         <TreeViewItem.Header>
           <StackPanel Orientation="Horizontal">
             <Image Source="{Binding XPath=@ref}" />
             <TextBlock Text="{Binding XPath=@Name}" />
           </StackPanel>
         </TreeViewItem.Header>
      </TreeViewItem>
   </HierarchicalDataTemplate>
</Window.Resources>
<Grid>
<TreeView Cursor="Hand" x:Name="_treeView" Width="160" Background="Transparent" Margin="0,10,10,10" BorderBrush="Transparent" BorderThickness="0"

                           ItemsSource="{Binding XPath=//Book, Source={StaticResource XMLdata}}"

                           ItemTemplate="{StaticResource ResourceKey=Library}" />
