WPF下ListView 绑定xml数据源的方案

前端之家收集整理的这篇文章主要介绍了WPF下ListView 绑定xml数据源的方案前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

对于ListView的数据源是Xml的情况很多见,如果Xml是以元素为主封装数据源应该容易理解,这里提供的是xml是以属性为主的形式下,并且所有列动态生成的绑定方案


即类似如下的数据源

<?xml version="1.0" encoding="gb2312"?>
<items>
  <item id="18" procode="122" entrustunit="1" entrustunitname="123" appler="123321" entrustdate="2014-8-13 0:00:00" principal="0" principalname="admin" proname="312" pronum="122" proorder="232" protype="312" testtype="3" testtypename=" " taskstate="3" taskstatename="进行中"/>
  <item id="16" procode="vreter" entrustunit="1" entrustunitname="123" appler="cell" entrustdate="2014-8-12 0:00:00" principal="" principalname="" proname="er" pronum="12" proorder="" protype="er" testtype="3" testtypename=" " taskstate="1" taskstatename="未发布"/>
  <item id="12" procode="4" entrustunit="1" entrustunitname="123" appler="飞" entrustdate="2014-8-12 0:00:00" principal="" principalname="" proname="4" pronum="4" proorder="" protype="" testtype="3" testtypename=" " taskstate="1" taskstatename="未发布"/>

  <item id="5" procode="阿斯达" entrustunit="1" entrustunitname="123" appler="阿斯达" entrustdate="2014-8-6 0:00:00" principal="" principalname="" proname="123123" pronum="12" proorder="阿斯达" protype="" testtype="2" testtypename=" " taskstate="2" taskstatename="未开始"/>
  <item id="4" procode="12" entrustunit="1" entrustunitname="123" appler="12" entrustdate="2014-8-6 0:00:00" principal="" principalname="" proname="12" pronum="" proorder="1" protype="" testtype="2" testtypename=" " taskstate="3" taskstatename="进行中"/>
  <item id="1" procode="312" entrustunit="1" entrustunitname="123" appler="12" entrustdate="2014-8-4 0:00:00" principal="0" principalname="admin" proname="123" pronum="12" proorder="12" protype="123" testtype="1" testtypename=" " taskstate="4" taskstatename="已结束"/>
</items>

        <ListView Height="331" HorizontalAlignment="Left" Margin="12,57,0" Name="listView1" VerticalAlignment="Top" Width="1230">
