我可以插入多个< tbody>元素转换为asp:Table的程序?

问题描述

另请参阅相关问题可以有多个< tbody>在同一< table>中?

说我想使用asp:table生成下表:

Say I want to generate the following table using asp:table:

<table>
    <thead>
        ...stuff...
    </thead>
    <tbody class="odd">
        <th scope="tbody">CUSTOMER 1</th>
        <tr><td>#1</td><td>January</td></tr>
        <tr><td>#2</td><td>April</td></tr>
        <tr><td>#3</td><td>March</td></tr>
    </tbody>
    <tbody class="even">
        <th scope="tbody">CUSTOMER 2</th>
        <tr><td>#1</td><td>January</td></tr>
        <tr><td>#2</td><td>April</td></tr>
        <tr><td>#3</td><td>March</td></tr>
    </tbody>
    <tbody class="odd">
        <th scope="tbody">CUSTOMER 3</th>
        <tr><td>#1</td><td>January</td></tr>
        <tr><td>#2</td><td>April</td></tr>
        <tr><td>#3</td><td>March</td></tr>
    </tbody>
</table>

我可以以编程方式构建这些< tbody> /< tr> 元素吗?

Can I build these <tbody> / <tr> elements programmatically?

我尝试做类似的事情:

var x = new HtmlGenericControl("tbody");
x.Attributes["class"] = jobNum % 2 == 0 ? "even" : "odd";
TableRow xinfoRow = buildXInfoRow(job); x.Controls.Add(xinfoRow);
TableRow xdescriptionRow = buildXDescriptionRow(job); x.Controls.Add(xdescriptionRow);
myTable.Controls.Add(x);

但这只是给我一个错误，'Table'不能有'HtmlGenericControl'类型的子代.

But this just gives me the error 'Table' cannot have children of type 'HtmlGenericControl'.

我可以找到TableRow，TableCell，TableHeaderRow，TableHeaderCell等类，但是似乎找不到TableBody或TableHeader.我可以在页眉，正文或页脚中放置行:

I can find a TableRow, TableCell, TableHeaderRow, TableHeaderCell, etc. classes, but I can't seem to find TableBody or TableHeader. I can place rows within the header, body or footer:

descriptionRow.TableSection = TableRowSection.TableBody;

...但是我似乎无法将行分成多个不同的< tbody> 元素.我已经完全放弃了，开始使用< asp:ListView> 生成表，但是我很想知道是否可以做到这一点.

...but I can't seem to divide the rows into multiple different <tbody> elements. I've pretty much given up and gone to using an <asp:ListView> to generate the table, but I'm interested to see if this can be done.

推荐答案

仅凭其属性，就无法增强< tbody> 的 asp:Table 功能.但是我知道有三种方法可以实现此目的:

There is no way to enhance asp:Table functionality for <tbody> just with its properties. But there are three ways I know how you can implement this:

1. 创建一个从 System.Web.UI.WebControls.Table 派生的类，并使用您自己的逻辑覆盖其方法 RenderContents .查看.NET Framework本机方法的默认实现( Table.RenderContents )，以了解如何使用任何反汇编程序(如.NET Reflector)来管理它.

1. Create a class derived from System.Web.UI.WebControls.Table and override its method RenderContents with your own logic. Look a default implementation of .NET Framework native method (Table.RenderContents) to see how you can manage it by using any disassembler like .NET Reflector.

(最困难的方法)创建带有子类(TableBody，TableBodyRow，TableBodyCell等)的自己的 asp:Table ；)

(the hardest way) Create your own asp:Table with subclasses (TableBody, TableBodyRow, TableBodyCell, etc.) ;)

改为使用 asp:Repeater ，例如:

<asp:Repeater ...>
  <HeaderTemplate>
    <table>
      <thead>
        ..stuff..
      </thead>
      <tbody class="odd">
  </HeaderTemplate>
  <ItemTemplate>
    <tr> ..stuff.. </tr>
  </ItemTemplate>
  <SeparatorTemplate>
    <asp:PlaceHolder Visible='<%# (Container.ItemIndex + 1) % 3 %>' runat="server">
       <tbody class="<%# (Container.ItemIndex + 1) % 6 > 3 ? "even" : "odd" %>">
    </asp:PlaceHolder>
  </SeparatorTemplate>
  <FooterTemplate>
      </tbody>
    </table>
  </FooterTemplate>
</asp:Repeater>

甚至使用子转发器(如果您有两个集合(按月列出的客户和价值)可能是更好的方法

or even with sub repeater (may be the better way if you have two collections -- customers and values by month)

P.S .:通过查看您的示例，就HTML规则而言，< tbody> 中的< th> 是不正确的.不要在那里使用它.

P.S.: By looking your example, <th> inside <tbody> is incorrect in terms of HTML rules. Don't use it there.
