将XML放在WPF中的DataGrid视图中 [英] Put XML in a DataGrid view inside WPF

问题描述

我的WPF应用程序中有一个DataGrid，我希望它包含我的XML文件中的值。 DataGrid如下所示：

 < TabItem Header =Datacopy> 
< Grid> 
< DataGrid x：Name =GrdDatacopyHorizo​​ntalAlignment =LeftMargin =7,7,0,0VerticalAlignment =TopHeight =320Width =640> 
< DataGrid.Columns> 
< DataGridTextColumn DisplayMemberBinding ={Binding Path = Source}Header =Bron：>< / DataGridTextColumn> 
< DataGridTextColumn DisplayMemberBinding ={Binding Path = Destination}Header =Doel：>< / DataGridTextColumn> 
< /DataGrid.Columns> 
< / DataGrid> 
< / Grid> 
< / TabItem> 
  

我的XML：

 < DataCopy Dir =H：\O365-Source> 
< Row Source =C：\TempDestination =Temp/> 
< Row Source =C：\DownloadsDestination =Downloads/> 
< Row Source =C：\MuziekDestination =Muziek/> 
< / DataCopy> 
  

我可以为datagrid创建一个对象

  $ DatacopySet = @ {} 
 $ XmlOffice365.Office365.Datacopy.Row | ForEach {
 $ DatacopySet.add（$ _。Source））
 $ DatacopySet.add（$ _。Destination））
} 
 $ DatacopySet | ForEach-Object {....................} 
  

但是当我粘贴到我的整个应用程序崩溃时，它应该是绑定的东西。

如何在datagrid中获取我的XML密钥，可以编辑这些。

我找到了一些样本，但我无法让它工作...

希望有人可以帮助，或者有其他方法来简单地编辑和添加这个一些设置？

解决方案

您可以按以下方式显示您的xml数据

 < Window x：Class =WpfApplication3.MainWindow
 xmlns =http://schemas.microsoft.com/winfx/2006/xaml/演示文稿
 xmlns：x =http://schemas.microsoft.com/winfx/2006/xaml
 xmlns：d =http://schemas.microsoft.com/expression/blend/ 2008
 xmlns：local =clr-namespace：WpfApplication3
 xmlns：mc =http://schemas.openxmlformats.org/markup-compatibility/2006
 Title =MainWindow 
宽度=525
高度=350
 mc：Ignorable =d> 
< Window.Resources> 
< XmlDataProvider x：Key =XmlDataCopyXPath =DataCopy> 
< x：XData> 
< DataCopy xmlns =Dir =H：\O365-Source> 
< Row Destination =TempSource =C：\Temp/> 
< Row Destination =下载Source =C：\Downloads/> 
< Row Destination =MuziekSource =C：\Muziek/> 
< / DataCopy> 
< / x：XData> 
< / XmlDataProvider> 
< /Window.Resources> 
< Grid> 
< DataGrid AutoGenerateColumns =FalseItemsSource ={Binding Source = {StaticResource XmlDataCopy}，XPath ='Row'}> 
 
< DataGrid.Columns> 
< DataGridTextColumn Binding ={Binding XPath ='@ Destination'}Header =Destination/> 
< DataGridTextColumn Binding ={Binding XPath ='@ Source'}Header =Source/> 
< /DataGrid.Columns> 
< / DataGrid> 
 
< / Grid> 
  

注意：

-XmlDataProvider可以与不同的源一起使用，包括URI

- 在xml-snippet中注明空的xmlns = 。您很容易遇到命名空间问题。

- 如果XmlDataProvider的Source是内存中的一个变量，也可以编辑文档。您必须手动调用XmlDocument.Save（）。

I have a DataGrid inside my WPF application and I would like it to contain values from my XML file. The DataGrid is shown below:

<TabItem Header="Datacopy">
    <Grid>
        <DataGrid x:Name="GrdDatacopy" HorizontalAlignment="Left" Margin="7,7,0,0" VerticalAlignment="Top" Height="320" Width="640">
            <DataGrid.Columns>
                <DataGridTextColumn DisplayMemberBinding="{Binding Path = Source}" Header="Bron:"></DataGridTextColumn>
                <DataGridTextColumn DisplayMemberBinding="{Binding Path = Destination}" Header="Doel:"></DataGridTextColumn>
            </DataGrid.Columns>
        </DataGrid>
    </Grid>
</TabItem>

My XML:

<DataCopy Dir="H:\O365-Source">
  <Row Source="C:\Temp" Destination="Temp" />
  <Row Source="C:\Downloads" Destination="Downloads" />
  <Row Source="C:\Muziek" Destination="Muziek" />
</DataCopy>

I can create a object for the datagrid

$DatacopySet = @{}
$XmlOffice365.Office365.Datacopy.Row | ForEach {
    $DatacopySet.add($_.Source))
    $DatacopySet.add($_.Destination))
}
$DatacopySet | ForEach-Object { .................... }

But when I paste in the secion my whole app crashes, it should be something with the bindings.

How can I get my XML keys in the datagrid and be able to edit these.

I've found some samples but I couldn't get this to work...

Hope that someone can help, or is there a other way to easaly edit and add values in this sort of setting?

You can display your xml data in the following way

<Window x:Class="WpfApplication3.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:local="clr-namespace:WpfApplication3"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    Title="MainWindow"
    Width="525"
    Height="350"
    mc:Ignorable="d">
<Window.Resources>
    <XmlDataProvider x:Key="XmlDataCopy" XPath="DataCopy">
        <x:XData>
            <DataCopy xmlns="" Dir="H:\O365-Source">
                <Row Destination="Temp" Source="C:\Temp" />
                <Row Destination="Downloads" Source="C:\Downloads" />
                <Row Destination="Muziek" Source="C:\Muziek" />
            </DataCopy>
        </x:XData>
    </XmlDataProvider>
</Window.Resources>
<Grid>
    <DataGrid AutoGenerateColumns="False" ItemsSource="{Binding Source={StaticResource XmlDataCopy}, XPath='Row'}">

        <DataGrid.Columns>
            <DataGridTextColumn Binding="{Binding XPath='@Destination'}" Header="Destination" />
            <DataGridTextColumn Binding="{Binding XPath='@Source'}" Header="Source" />
        </DataGrid.Columns>
    </DataGrid>

</Grid>

Note:

-XmlDataProvider can be used with different Sources, including URIs

-Note the empty xmlns="" in the xml-snippet. You easily run into namespace issues otherwise.

-Editing the document is also possible in case the XmlDataProvider's Source is a variable in memory. You must call XmlDocument.Save() manually.
