我遇到了问题。我想我可能接近解决方案,但似乎无法到达那里。我有一个XMLDoc,它从存储的Proc加载到数据集中,并从中提取xml,(不要认为我可以更改任何这部分)。 XML看起来像这样:
<data>
<datanode>
<name>11</name>
<group>G1</group>
<value>val1</value>
</datanode>
<datanode>
<name>12</name>
<group>G1</group>
<value>val2</value>
</datanode>
<datanode>
<name>21</name>
<group>G2</group>
<value>val1</value>
</datanode>
<datanode>
<name>22</name>
<group>G2</group>
<value>val2</value>
</datanode>
<datanode>
<name>23</name>
<group>G2</group>
<value>val3</value>
</datanode>
<datanode>
<name>31</name>
<group>G3</group>
<value>val1</value>
</datanode>
<datanode>
<name>32</name>
<group>G3</group>
<value>val2</value>
</datanode>
<datanode>
<name>33</name>
<group>G3</group>
<value>val3</value>
</datanode>
<datanode>
<name>34</name>
<group>G3</group>
<value>val4</value>
</datanode>
</data>
我需要使用嵌套转发器来显示此信息。我想要的是通过“组”节点对其进行分组,然后显示属于该“组”节点的每个“数据节点”。所以它在页面上看起来像这样:
G1 - has 2 nodes
11 - Val1
12 - Val2
G2 - has 3 nodes
21 - Val1
22 - Val2
23 - Val3
etc
到目前为止我所拥有的: Default.aspx的:
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<p>
COUNT: <asp:Literal runat="server" ID="Literal3" Text='<%# XPath("count(group)") %>' />
<br />Text: <asp:Literal runat="server" ID="Literal4" Text='<%# XPath("text()") %>' />
<br />Group: <asp:Literal runat="server" ID="Literal2" Text='<%# XPath("group") %>' />
<br />ID: <asp:Literal runat="server" ID="displayname" Text='<%# XPath("name") %>' />
<br />VAL: <asp:Literal runat="server" ID="Literal1" Text='<%# XPath("value") %>' />
</p>
</ItemTemplate>
</asp:Repeater>
Default.aspx.cs
public partial class _Default : System.Web.UI.Page
{
private XmlNodeList nodelist;
protected void Page_Load(object sender, EventArgs e)
{
XmlDocument doc = new XmlDocument();
doc.Load(@"C:\development\testforWork\WebApplication1\WebApplication1\data.xml");
nodelist = doc.SelectNodes("//datanode[not(group=preceding-sibling::datanode/group)]/group");
//nodelist = doc.SelectNodes("//datanode[group='G2']");
Repeater1.DataSource = nodelist;
Repeater1.DataBind();
}
}
我可以让他们一个接一个地显示每个datanode,但我无法弄清楚如何嵌套转发器并进行分组。我对XPath和转发器很新,并且认为我必须在我的知识上有一些差距而且无法连接点(除非我完全跑错了路)。

答案 0 :(得分:4)
好的,经过一些实验后找到了我的解决方案:
<asp:Repeater ID="repManifestNumber" runat="server" DataSource="<%# ManifestDataTemp %>">
<ItemTemplate>
Manifest Number:
<%# CurrentManifestNumber = XPath("manifest_number").ToString() %>
- <%# XPath("count(..//box_item[manifest_number=" + CurrentManifestNumber + "])")%> Box(s)
<div class="showhide">
<asp:Repeater ID="repMainfestDetail" runat="server" DataSource='<%# ((XmlNode)Container.DataItem).SelectNodes("..//box_item[manifest_number=" + CurrentManifestNumber + "]") %>'>
<HeaderTemplate>
<table class="orders" id="manifest_<%# CurrentManifestNumber %>">
<tr>
<th>
Box Number
</th>
<th>
Date Dispatched
</th>
<th>
<input type="checkbox" class="checkboxflipflop_local" />
- Select All
</th>
</tr>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</HeaderTemplate>
<ItemTemplate>
<tr class="odd-table-row">
<td>
<asp:Literal runat="server" ID="litBoxNumber" Text='<%# XPath("box_number") %>' />
</td>
<td>
<asp:Literal runat="server" ID="litErpDispatched" Text='<%# Convert.ToDateTime(XPath("date_dispatched")).ToString("dd/MM/yyyy") %>' />
</td>
<td>
<asp:Literal runat="server" ID="litHiddenXmlNode" Text='<%# ((XmlNode)Container.DataItem).OuterXml %>'
Visible="false"></asp:Literal>
<asp:CheckBox ID="chkIsReceived" runat="server" Checked="false" CssClass="storecheckbox" />
</td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>
</div>
</ItemTemplate>
</asp:Repeater>
希望这可能在将来帮助其他人(或者当我再次忘记它时帮助我)。
