可以看到 有 一个出发 PageChanged 的事件
后台.cs protected void CustomRepeater1_PageIndexChanged(object sender, GridViewPageEventArgs e)
{
yr_Category.CurrentPageIndex = e.NewPageIndex;//指定当前页
yr_Category.DataSource = //这个你应该知道了
yr_Category.DataBind();
p1.PageCount = yr_Category.ItemCount;//给分页控件 你的记录数
}去看看吧 效果还不错,不过我没有处理他的回发事件 因为在 触发前后 都重新绑定了数据源,所以不要再里面加入Button 的事件
毕竟是给前台用的 呵呵~
我们经常要用到 比如 一个专门放静态资源的 img.xx.com 可能就用到了我这个控件代码：先在web.config加上<configSections>
<!--Register a FtpConfig -->
<section name="FtpConfig" type="System.Configuration.SingleTagSectionHandler"/>
</configSections>
<FtpConfig Server="192.168.1.111" Port="21" UserName="mars" Password="mars" RootPath=""/>
System.Configuration.SingleTagSectionHandler 这个类大家可以去看看 msdn 的解释
然后处理下你从wen.config 获取的 配置

你先试试吧
很不错的是 url 的分页
效果不错 ,很快~
汗...这里 就不要叫我浪客了吧
大家多顶顶 明天给大家链接下载
一共有三个控件
1是 数据控件 针对IList 的
2 是 分页控件 Url 分页 效果不错de
3是 FTP上传 控件 请高人指点这个 我还是在乎安全问题~
<add key="ImageMime" value="image/pjpeg|image/bmp|image/gif|image/png|image/jpeg|image/tiff"/>
数据控件那个还在整理中 谢谢大家了~~~~~

朋友们 帮我顶顶噢
我已经整理好了上传控件的 地址在这里 http://www.ysmv.com/upload.rar数据控件的地址在:http://www.ysmv.com/DataControl.rar

编译成类库 然后自己添加就好了的~~最近还在写其他很多控件
到时候全部 这样给大家看咯 其实本来是打算 直接发bll的 我已经签名了 算了 大家一起学习吧
最近正在组织一个团队 做开源项目
有兴趣 可以联系
群:9778240
或者我:83873308希望大家多交流 吧
我也是个新手 还请高手们指教了~

这个控件的不好的地方就是
分页的 ReBind 重新banding的
如果还要处理回发事件 就有点问题
不过我在做一个可以处理回发的 url分页的控件
还要解决url 重写的回发问题
