WPF 使用XML做爲綁定源時Xaml注意事項

直接在xaml定義時xml時應該注意的！

xml數據

 <?xml version="1.0" encoding="utf-8"?>
  <StringList >
                    <Srtring Id="1">
                        <Name>A</Name>
                        <Age>10</Age>
                        <Nub>001</Nub>
                    </Srtring>
                    <Srtring Id="2">
                        <Name>B</Name>
                        <Age>20</Age>
                        <Nub>002</Nub>
                    </Srtring>
                    <Srtring Id="3">
                        <Name>C</Name>
                        <Age>30</Age>
                        <Nub>003</Nub>
                    </Srtring>
                    <Srtring Id="4">
                        <Name>D</Name>
                        <Age>40</Age>
                        <Nub>004</Nub>
                    </Srtring>
                    <Srtring Id="5">
                        <Name>A</Name>
                        <Age>50</Age>
                        <Nub>005</Nub>
                    </Srtring>
                </StringList>

 

若是直接在Xaml頁面中定義則是：

使用XmlDataProvider，並設置key，以及Xpath的源，xpath則是xml在被綁定時起始數據的起點，但不包括自身（不設置也能夠，可是須要在設置綁定時設置）

也就是xpath設定爲StringList，綁定時的起點則是String

且注意的是：XAML頁面中不能夠包含<?xml version="1.0" ?>字樣，會報錯。還有須要在xml根部加上xmlns=""

例子：

   <Window.Resources>
        <XmlDataProvider   x:Key="xmlData"  >
            <x:XData>
                <StringList xmlns="">
                    <String Id="1">
                        <Name>A</Name>
                        <Age>10</Age>
                        <Nub>001</Nub>
                    </String>
                    <String Id="2">
                        <Name>B</Name>
                        <Age>20</Age>
                        <Nub>002</Nub>
                    </String>
                    <String Id="3">
                        <Name>C</Name>
                        <Age>30</Age>
                        <Nub>003</Nub>
                    </String>
                    <String Id="4">
                        <Name>D</Name>
                        <Age>40</Age>
                        <Nub>004</Nub>
                    </String>
                    <String Id="5">
                        <Name>A</Name>
                        <Age>50</Age>
                        <Nub>005</Nub>
                    </String>
                </StringList>
            </x:XData>
        </XmlDataProvider>
    </Window.Resources>
    <Grid>
        <ListView ItemsSource="{Binding Source={StaticResource xmlData},XPath=StringList/*}">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="Name" Width="60" DisplayMemberBinding="{Binding XPath=Name}" />
                    <GridViewColumn Header="Age" Width="60" DisplayMemberBinding="{Binding XPath=Age}" />
                    <GridViewColumn Header="Nub" Width="60" DisplayMemberBinding="{Binding XPath=Nub}" />
                </GridView>
            </ListView.View>
        </ListView>

    </Grid>

若是想要獲取屬性則是須要使用@，而且確保xpath路徑正確

例如

 <ListView  ItemsSource="{Binding Source={StaticResource xmlData},XPath=/StringList/*}">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="Id" Width="60" DisplayMemberBinding="{Binding XPath=@Id}"  />
                    <GridViewColumn Header="Id" Width="60" DisplayMemberBinding="{Binding XPath=Age}" />
                    <GridViewColumn Header="Id" Width="60" DisplayMemberBinding="{Binding XPath=Nub}" />
                </GridView>
            </ListView.View>
        </ListView>
