我有一个生气的老板，如果我再浪费一天的话会打败我的：-P许多业力指向可以解决我的困境的ajax专家。
但更多细节：我想拥有一个AccordionPane，它可以从XML源获取一堆链接，并从所述源中填充自身。
解决方案
可能有一种更性感的方式，但这是可行的。根据需要填充数据源。这只是出于演示目的。 PrettyTitle()的同上技巧关键是要记住手风琴中有两种物品类型。
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Accordion Binding</title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="AjaxScriptManager" runat="server">
</asp:ScriptManager>
<div>
<cc1:Accordion ID="AccordionControl" runat="server"
onitemdatabound="AccordionControl_ItemDataBound">
<Panes></Panes>
<HeaderTemplate>
<asp:Label ID="HeaderLabel" runat="server" />
</HeaderTemplate>
<ContentTemplate>
<asp:Literal ID="ContentLiteral" runat="server" />
<asp:HyperLink ID="ContentLink" runat="server" />
</ContentTemplate>
</cc1:Accordion><asp:xmldatasource runat="server" ID="RockNUGTwitter" ></asp:xmldatasource>
</div>
</form>
</body>
</html>
后面的代码是：
Using System;
using System.Web.UI.WebControls;
using System.Xml;
namespace Ajaxy
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Fill();
}
private void Fill()
{
PopulateDataSource();
AccordionControl.DataSource = RockNUGTwitter.GetXmlDocument().SelectNodes("//item");
AccordionControl.DataBind();
}
private void PopulateDataSource()
{
XmlDocument RockNugTwitterRSSDocument = new XmlDocument();
RockNugTwitterRSSDocument.Load("http://twitter.com/statuses/user_timeline/15912811.rss");
RockNUGTwitter.Data = RockNugTwitterRSSDocument.OuterXml;
}
protected void AccordionControl_ItemDataBound(object sender, AjaxControlToolkit.AccordionItemEventArgs e)
{
XmlNode ItemNode = (XmlNode)e.AccordionItem.DataItem;
if(e.AccordionItem.ItemType == AjaxControlToolkit.AccordionItemType.Content)
{
HyperLink ContentLink = (HyperLink)e.AccordionItem.FindControl("ContentLink");
ContentLink.NavigateUrl = ItemNode.SelectSingleNode("link").InnerText;
Literal ContentLiteral = (Literal)e.AccordionItem.FindControl("ContentLiteral");
ContentLiteral.Text = ItemNode.SelectSingleNode("title").InnerText;
ContentLink.Text = "Link";
}
else if(e.AccordionItem.ItemType == AjaxControlToolkit.AccordionItemType.Header)
{
Label HeaderLabel = (Label) e.AccordionItem.FindControl("HeaderLabel");
HeaderLabel.Text = PrettyTitle(ItemNode.SelectSingleNode("title").InnerText);
}
}
private string PrettyTitle(string FullItem)
{
string PrettyString = FullItem.Replace("RockNUG: ", "");
string[] Words = PrettyString.Split(' ');
const int MAX_WORDS_TOSHOW = 4;
int WordsToShow = MAX_WORDS_TOSHOW;
if(Words.Length < MAX_WORDS_TOSHOW)
{
WordsToShow = Words.Length;
}
PrettyString = String.Join(" ", Words, 0, WordsToShow);
if (Words.Length > WordsToShow)
{
PrettyString += "...";
}
return PrettyString;
}
}
}
