我正在开发一个wpf中的应用程序,其中我有一个数据网格。我希望从xml动态添加datagrid列。
<Department Name='D1' TotalCapacity='5'>
<Class Name='c1' Capacity='3'></Class>
<Class Name='c2' Capacity='2'></Class>
</Department>
<Department Name='D2' TotalCapacity='10'>
<Class Name='c1' Capacity='5'></Class>
<Class Name='c3' Capacity='5'></Class>
</Department>
现在,基于这个xml我希望datagrid显示为:
DepartmentName TotalCapacity c1 c2 c3
D1 5 3 2 -
D2 10 5 - 5
答案 0 :(得分:0)
我很好奇,并没有做过你之前想做的事情,所以我想我会给它一个刺。通过关于这个主题的this MSDN article,我想出了这个:
<Grid>
<Grid.Resources>
<XmlDataProvider x:Key="DepartmentData" XPath="Departments/Department">
<x:XData>
<Departments xmlns="">
<Department Name='D1' TotalCapacity='5'>
<Class Name='c1' Capacity='3'/>
<Class Name='c2' Capacity='2'/>
</Department>
<Department Name='D2' TotalCapacity='10'>
<Class Name='c1' Capacity='5'/>
<Class Name='c3' Capacity='5'/>
</Department>
</Departments>
</x:XData>
</XmlDataProvider>
</Grid.Resources>
<DataGrid ItemsSource="{Binding Source={StaticResource DepartmentData}}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Department Name" Binding="{Binding XPath=@Name}"/>
<DataGridTextColumn Header="Total Capacity" Binding="{Binding XPath=@TotalCapacity}"/>
<DataGridTextColumn Header="c1">
<DataGridTextColumn.Binding>
<Binding XPath="Class[@Name='c1']/@Capacity"/>
</DataGridTextColumn.Binding>
</DataGridTextColumn>
<DataGridTextColumn Header="c2">
<DataGridTextColumn.Binding>
<Binding XPath="Class[@Name='c2']/@Capacity"/>
</DataGridTextColumn.Binding>
</DataGridTextColumn>
<DataGridTextColumn Header="c3">
<DataGridTextColumn.Binding>
<Binding XPath="Class[@Name='c3']/@Capacity"/>
</DataGridTextColumn.Binding>
</DataGridTextColumn>
</DataGrid.Columns>
</DataGrid>
</Grid>
结果:
祝你好运!

我刚刚意识到你要求动态添加列 - 我不确定是否有一种直接的方法可以做到这一点,因为你的XML的结构格式不适合开箱即用的表格式显示(我不得不使用一些XPath魔法将XML转换为平面格式)。希望这会让你走上正确的道路。
