【问题描述】：

我想以 MVVM 样式显示 xamDataGrid 中 products.xml 中的数据。绑定无法正常工作。 Product 节点中的值必须添加到 xamDatagrid 中的组合框字段。组合框不显示任何数据。有人可以教我如何解决这个问题吗？

产品.xml

<?xml version="1.0" encoding="utf-8" ?>
<WG>
  <WGT>
    <TName>tanme1</TName>
    <Fname>fname1</Fname>
    <Product>Product1</Product>
    <Product>Product2 </Product>
  </WGT>
  <WGT>
    <TName>tanme2</TName>
    <Fname>fname2</Fname>
  </WGT>
  <WGT>
    <TName>tanme1</TName>
    <Fname>fname1</Fname>
    <Product>Product1</Product>
    <Product>Product2 </Product>
    <Product>Product3 </Product>
    <Product>Product4 </Product>
  </WGT>
  <WGT>
    <TName>tanme5</TName>
    <Fname>fname5</Fname>

  </WGT>
  <WGT>
    <TName>tanme1</TName>
    <Fname>fname1</Fname>
    <Product>Product1</Product>
    <Product>Product2 </Product>
    <Product>Product3 </Product>
    <Product>Product4 </Product>
    <Product>Product5 </Product>
    <Product>Product6 </Product>

  </WGT>
</WG>

我终于能够找出解决方案。我把它贴在这里是为了帮助像我这样的人。

<Setter Property="ItemsSource" Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type igDP:CellValuePresenter}}, Path=Record.DataItem.Product}" />
                                            <Setter Property="DisplayMemberPath" Value="Value" />
