我有一个中继器控件绑定到通用List<>
。
中继器的项目都有其自己的<div>
标签,因此具有良好的块视觉效果,以及所有项目的标准占位符。
通过自定义排序,我能够在其自己的标准中安排结果,但是现在我需要一些不是标准的东西。
我需要能够在 <div>
块中选择选定的项目,然后将其移至中继器项目列表的底部或顶部。
有什么办法可以做到这一点?通过绑定,或使用RepeAter的repeater_ItemDataBound()
方法?
代码很长..所以我将发布我认为"需要知道"的内容。
填充通用列表
while (rdr.Read())
{
challenge.Add(new ChallengeList
{
GameName = rdr["gameName"].ToString(),
CreatorName = rdr["creatorName"].ToString(),
MediatorName = rdr["mediatorName"].ToString(),
ChallengeID = rdr["challengeId"].ToString(),
ChallengeAccepted = rdr["accepted"].ToString(),
MatchDate = DateTime.Parse(rdr["matchDate"].ToString()).ToString("dd MMMM yyyy hh:mm")
});
}
-same方法 - 对数据进行排序,然后绑定
switch (sort)
{
case "name":
Comparison<ChallengeList> name = ChallengeList.CompareGameName;
challenge.Sort(name);
break;
case "date":
Comparison<ChallengeList> date = ChallengeList.CompareDate;
challenge.Sort(date);
break;
case "status":
Comparison<ChallengeList> status = ChallengeList.CompareStatus;
challenge.Sort(status);
break;
}
rptChallenges.DataSource = challenge;
rptChallenges.DataBind();
通用列表类(带排序)

我的问题的真实应用如果有"粘性"匹配 - 无论日期,状态或名称
我建议您在看到中继器之前订购列表中的数据。如果不可能给定数据的结构和/或中继器的项目模板,请您提供数据的样本和中继器,以便我们进一步帮助?
编辑Asker发布代码
而不是将挑战设定为中继器的数据源,您应该将所有需要在列表顶部的项目分为新列表中,然后将其他其他项目附加到顶级项目的末尾。<<<<<<<<<<<<
类似的东西:
var topItmes = new List<ChallengeList>();
var otherItmes = new List<ChallengeList>();
foreach (var item in challenge)
{
if(/*item needs to be on top*/)
{
topItmes.Add(item);
}
else
{
otherItmes.Add(item);
}
}
topItmes.AddRange(otherItmes);
取决于一个项目在顶部的标准,您可以使用Linq表达式来简化此代码。
