问题描述
我花了很多时间试图弄清楚如何将我的 XML 文件中的数据绑定到 TreeView 控件,但我不知道从哪里开始.我什至尝试通过 Xml 数据的双向绑定到 WPF TreeView 和 Josh Smith 在 codeproject 上的代码示例,但仍然无法理解如何开始!!!
I have spend a lot of time trying to figure out how to bind data in my XML file to the TreeView control but I do not know where to start. I even tried going through Two-way binding of Xml data to the WPF TreeView and Josh Smith's code sample on codeproject, but still can't understand how to begin!!!
我在文件C:\SPDependencies.xml"中有 XML(如果需要,我可以更改格式)!!!:
I have XML in in a file "C:\SPDependencies.xml" (I can change the format if required)!!!:
<node type="SPDependencies" Name="SPDependencies">
<node type="StoredProc" Name="SP1">
<node type="OperationType" Name="Type1">
<node type="TableName" Name="Table1"/>
<node type="TableName" Name="Table2"/>
</node>
<node type="OperationType" Name="Type2">
<node type="TableName" Name="Table1"/>
<node type="TableName" Name="Table2"/>
</node>
.....
</node>
<node type="StoredProc" Name="SP2">
<node type="OperationType" Name="Type1">
...
...
</node>
</node>
我需要以下列格式在 Treeview 控件中显示它:
I need to display this in the Treeview control in the following format:
<SP1>
<Type1>
<Table1>
<Table2>
<Table3>
<Type2>
<Table1>
<Table2>
<Table3>
<SP2>
<Type1>
........
谢谢,阿比.
推荐答案
给定以下 xml 文件:
Given the following xml file:
<node type="SPDependencies" Name="SPDependencies">
<node type="StoredProc" Name="SP1">
<node type="OperationType" Name="Type1">
<node type="TableName" Name="Table1"/>
</node>
<node type="OperationType" Name="Type2">
<node type="TableName" Name="Table1"/>
</node>
</node>
<node type="StoredProc" Name="SP2">
<node type="OperationType" Name="Type1">
</node>
</node>
</node>
查看:
<Window x:Class="Tree.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Tree"
Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
<local:ViewModel />
</Window.DataContext>
<Window.Resources>
<HierarchicalDataTemplate x:Key="template">
<TextBlock Text="{Binding XPath=@Name}" />
<HierarchicalDataTemplate.ItemsSource>
<Binding XPath="node" />
</HierarchicalDataTemplate.ItemsSource>
</HierarchicalDataTemplate>
</Window.Resources>
<Grid DataContext="{Binding Path=XmlData}">
<TreeView ItemsSource="{Binding}" ItemTemplate="{StaticResource template}">
</TreeView>
</Grid>
</Window>
查看模型:
public class ViewModel
{
public XmlDataProvider XmlData { get; set; }
public ViewModel()
{
XmlData = new XmlDataProvider();
XmlData.Source = new Uri(@"C:\input.xml");
XmlData.XPath = "node";
}
}
输出:
如果您只想显示根下方的节点,只需将 XPath 更改为:
If you only want to show the nodes below the root, simply change the XPath to:
XmlData.XPath = "/node/node";
