使用DataSet Xml数据链接的两个DataGridView

请帮助我链接两个DataGridViews。我有两个DataGridViews来显示xml文件。我将数据分成“两个表”“BasicData”和“Unbound” DataGridView1显示BasicData，而DataGridView2显示上述DataGridView中显示的每个“BasicData”表的链接“Unbound”。使用DataSet Xml数据链接的两个DataGridView

我试图链接是这样的：

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

问候，

我有我的XML文件是这样的：

您是否收到任何错误？数据源更改时，DGV不会自动更新。您通常必须将DataSource设置为null，然后将其设置为DataTable。或者在填充DataSet后添加绑定。 – jdweng

“未绑定”表在第二个DGV DataGridView2中未显示..... – user3051677

-1

尝试下面的XML，看看它是否工作

<?xml version="1.0" standalone="yes"?> 
<set> 
<BasicData> 
    <Elem1>1.00</Elem1> 
    <Elem2>3500.00</Elem2> 
    <Elem3>90.00</Elem3> 
    <Elem4>90.00</Elem4> 
    <Elem5>7140.00</Elem5> 
    <Elem6>25.70</Elem6> 
    <Elem7>300.00</Elem7> 
    <Elem8>2.40</Elem8> 
    <Elem9>0.70</Elem9> 
    <Elem10>0.83</Elem10> 
    <Elem11>0.012</Elem11> 
    <Elem12>0.15</Elem12> 
</BasicData> 

<Unbound> 
    <DL_FT> 10280.00 </DL_FT> 
    <HL_FT> 2000 </HL_FT>

我不应该为试图尝试隔离问题原因而获得负面评价。 – jdweng
