我想要做類似的信息（例如更新）：有沒有辦法將內部控件放入ASP.NET自定義控件中？
<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>
可能嗎？任何教程或指導方針？我不知道甚至搜索什麼，或者這是叫什麼，所以到目前爲止還沒有發現任何東西。內部控制？內部收集東西...？
使用ParseChildrenAttribute和PersistChildrenAttribute屬性：
[ParseChildren(false)]
[PersistChildren(true)]
public class MyControl : UserControl { }
這將導致你把基準內的任何控件：
<uc:MyControl runat="server">
<asp:TextBox runat="server" />
<uc:MyControl>
附加到你的用戶控件內容的控件集合的末尾。
但是，如果您想擁有一組控件，則應該使用服務器控件而不是用戶控件。對於像這樣工作的控件：
<foo:TabControl runat="server">
<Tabs>
<foo:Tab CssClass="myclass" Title="Hello World" />
</Tabs>
</foo:TabControl>
您需要一個具有Tabs屬性的Control類; Tabs屬性應該是Collection;它應該包含Tab類型的對象。我創建了這裏的三個類別：
[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");
}
}
}
而且標籤類：
public class Tab
{
public string CssClass { get; set; }
public string Title { get; set; }
}
而且標籤集合：
public class TabCollection : Collection<Tab> { }
跟進
雷克斯中號提供了答案，但只是想跟進我對p的發現osterity。
好像你可以做兩種：
<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>
OR
<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>
然後在代碼：
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; }
}
}
}
這顯然會改變（我將是從閱讀web.sitemap以及其他更改），但這應該讓任何人都有相同的需求。

我會給這個旋轉。我現在正在使用自定義（服務器？）控件;我認爲「UC」可能導致你相信這是一個用戶控制。 – rball 2009-03-03 00:33:36
