Question

请帮我链接两个DataGridViews。我有两个DataGridViews来显示xml文件。我把数据分成了两个表＆＃34; ＆＃34; BasicData＆＃34;和＃34; Unbound＆＃34; DataGridView1显示BasicData，而DataGridView2显示链接＆＃34; Unbound＆＃34;对于每个＆＃34; BasicData＆＃34;表格显示在上面的DataGridView。

我尝试过像这样的链接：

BasicData_BindingSource1.DataSource = dataset_DS1.Tables("set")
BasicData_BindingSource1.DataMember = "BasicData"

Unbound_BindingSource2.DataSource = BasicData_BindingSource1
Unbound_BindingSource2.DataMember = "Unbound"

DataGridView1.DataSource = BasicData_BindingSource1
DataGridView2.DataSource = Unbound_BindingSource2

此致

我的xml文件是这样的：

<?xml version="1.0" standalone="yes"?>

<main xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<set Attr1="Attr1Value" Attr2="Attr2Value">

尝试按照xml查看是否有效

<?xml version="1.0" standalone="yes"?>
<set>
 <BasicData>
    <Elem1>1.00</Elem1>
    <Elem2>3500.00</Elem2>
