我想做类似的事情（更新的例子）：
<uc:Tabs>
<Tab Name="A handy tab">
<Node Url="~/Default.aspx" />
<Node Url="~/Node2.aspx" />
</Tab>
<Tab Name="Another handy tab">
<Node Url="~/Neato.aspx" />
<Node Url="~/Node3.aspx" />
<Node Url="~/Node4.aspx" />
</Tab>
<uc:Tabs>
可能的？有什么教程或操作方法吗？我不确定要搜索什么或这叫什么，所以到目前为止还没有找到任何东西。内部控制？内藏什么东西……？
使用ParseChildrenAttribute和PersistChildrenAttribute属性：
[ParseChildren(false)]
[PersistChildren(true)]
public class MyControl : UserControl { }
这将导致您放入参考中的任何控件：
<uc:MyControl runat="server">
<asp:TextBox runat="server" />
<uc:MyControl>
附加到您的 UserControl 内容的 Controls 集合的末尾。
但是，如果您想拥有一组控件，您可能应该使用服务器控件而不是用户控件。对于像这样工作的控件：
<foo:TabControl runat="server">
<Tabs>
<foo:Tab CssClass="myclass" Title="Hello World" />
</Tabs>
</foo:TabControl>
您需要一个具有 Tabs 属性的 Control 类；Tabs 属性应该是一个集合；它应该包含 Tab 类型的对象。我在这里创建了三个类：
[ParseChildren(true, "Tabs")]
public class TabControl: WebControl, INamingContainer
{
private TabCollection _tabs;
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
[PersistenceMode(PersistenceMode.InnerDefaultProperty)]
public TabCollection Tabs
{
get
{
if (_tabs == null)
{
_tabs = new TabCollection();
}
return _tabs;
}
}
protected override void Render(HtmlTextWriter writer)
{
foreach (Tab tab in Tabs)
{
writer.WriteBeginTag("div");
writer.WriteAttribute("class", tab.CssClass);
writer.Write(HtmlTextWriter.TagRightChar);
writer.Write("this is a tab called " + tab.Title);
writer.WriteEndTag("div");
}
}
}
和选项卡类：
public class Tab
{
public string CssClass { get; set; }
public string Title { get; set; }
}
和选项卡集合：
public class TabCollection : Collection<Tab> { }
跟进
Rex M 提供了答案，但只是想跟进我也为后代找到的内容。
似乎您可以执行以下任一操作：
<ui:Tabs runat="server">
<ui:Tab TabText="Blah">
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/More.aspx" />
<ui:Node Url="~/Another.aspx" />
</ui:Tab>
<ui:Tab TabText="Nanner">
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/More.aspx" />
<ui:Node Url="~/Another.aspx" />
</ui:Tab>
<ui:Tab TabText="High There">
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/More.aspx" />
<ui:Node Url="~/Another.aspx" />
</ui:Tab>
</ui:Tabs>
或者
<ui:Tabs runat="server">
<TabItems>
<ui:Tab InnerHeading="Big Huge Heading" TabText="Big">
<NodeItems>
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
</NodeItems>
</ui:Tab>
</TabItems>
<TabItems>
<ui:Tab InnerHeading="Hi ya" TabText="Hi">
<NodeItems>
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
<ui:Node Url="~/Default.aspx" />
</NodeItems>
</ui:Tab>
</TabItems>
</ui:Tabs>
然后在代码中：
namespace Controls
{
[ToolboxData("<{0}:Tabs runat=server></{0}:Tabs>"), ParseChildren(true, "TabItems")]
public class Tabs : BaseControl, INamingContainer
{
private TabCollection tabItems;
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
[PersistenceMode(PersistenceMode.InnerDefaultProperty)]
public TabCollection TabItems
{
get
{
if (tabItems == null)
{
tabItems = new TabCollection();
}
return tabItems;
}
}
protected override void Render(HtmlTextWriter writer)
{
writer.Write("<div id=\"tabs\" class=\"pane\" style=\"display: none\"><ul>");
int tabNumber = 1;
foreach (Tab tab in TabItems)
{
string li = string.Format("<li id=\"tab_{0}\"><a href=\"#tab{0}\"><span>{1}</span></a></li>", tabNumber, tab.TabText);
tabNumber++;
writer.Write(li);
}
writer.Write("</ul>");
tabNumber = 1;
foreach (Tab tab in TabItems)
{
string div = string.Format("<div id=\"tab{0}\" class=\"pane\"><h1>{1}</h1>", tabNumber, tab.InnerHeading);
tabNumber++;
writer.Write(div);
foreach (Node node in tab.NodeItems)
{
string a = string.Format("<a href='{0}'>{1}</a>", node.Url, "Text holder");
writer.Write(a);
}
writer.Write("</div>");
}
writer.Write("</div>");
}
}
public class TabCollection : List<Tab> { }
[ParseChildren(true, "NodeItems")]
public class Tab
{
private string tabText = string.Empty;
private string innerHeading = string.Empty;
private string showOn = string.Empty;
public string TabText
{
get { return tabText; }
set { tabText = value; }
}
public string InnerHeading
{
get { return innerHeading; }
set { innerHeading = value; }
}
public string ShowOn
{
get { return showOn; }
set { showOn = value; }
}
private NodeCollection nodeItems;
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
[PersistenceMode(PersistenceMode.InnerDefaultProperty)]
public NodeCollection NodeItems
{
get
{
if (nodeItems == null)
{
nodeItems = new NodeCollection();
}
return nodeItems;
}
}
}
public class NodeCollection : List<Node> { }
public class Node
{
private string url = string.Empty;
public string Url
{
get { return url; }
set { url = value; }
}
}
}
这显然会发生变化（我的将阅读 web.sitemap 以及其他变化），但这应该让任何有相同需求的人都能顺利进行。
