使用DataSet Xml數據鏈接的兩個DataGridView

請幫助我鏈接兩個DataGridViews。我有兩個DataGridViews來顯示xml文件。我將數據分成「兩個表」「BasicData」和「Unbound」 DataGridView1顯示BasicData，而DataGridView2顯示上述DataGridView中顯示的每個「BasicData」表的鏈接「Unbound」。使用DataSet Xml數據鏈接的兩個DataGridView

我試圖鏈接是這樣的：

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

問候，

我有我的XML文件是這樣的：

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

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

您是否收到任何錯誤？數據源更改時，DGV不會自動更新。您通常必須將DataSource設置爲null，然後將其設置爲DataTable。或者在填充DataSet後添加綁定。 – jdweng

「未綁定」表在第二個DGV DataGridView2中未顯示..... – user3051677

嘗試下面的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>

我不應該爲試圖嘗試隔離問題原因而獲得負面評價。 – jdweng
