sharepoint2010列表的分页实现迅雷样式效果
利用ListItemCollectionPosition和AspNetPage分页控件实现，效果图如下：
后台分页代码如下：
#region 私有方法
/// <summary>
/// 数据
/// </summary>
private void BindsData()
{
SPWeb m_objWeb = SPContext.Current.Web;
//
if (m_objWeb != null)
{
int _totalCount =0;
//
//
string listName = "测试列表";
//
SPList m_objList = m_objWeb.Lists[listName];
//
SPListItemCollection itemCollection = GetPageList(listName, this.AspNetPager_View.PageSize,
this.AspNetPager_View.CurrentPageIndex, out _totalCount, "", new string[] { "Title" });
//
this.Repeater1.DataSource = itemCollection;
this.Repeater1.DataBind();
this.AspNetPager_View.RecordCount = _totalCount;
}
}
/// <summary>

/// </summary>

private int GetListID(string listName, int pageSize, int curPage, string strWhere, string[] ViewField)
{
try
{
//得到当前站点
SPWeb m_objWeb = SPContext.Current.Web;
//得到列表
SPList m_objList = m_objWeb.Lists[listName];
SPQuery query = new SPQuery();
//设置查询条件
query.Query = strWhere;
//查询的字段
if (ViewField.Length > 0)
{
query.ViewFields = BuildViewFields(ViewField);
}
//条数限制
query.RowLimit = (uint)((curPage - 1) * pageSize);
//查询
SPListItemCollection m_objListItemColl = m_objList.GetItems(query);
//得到分页信息
string strPageInfo = m_objListItemColl.ListItemCollectionPosition.PagingInfo;
string page = strPageInfo.Substring(strPageInfo.LastIndexOf('=') + 1);
return Convert.ToInt32(page);
}
catch
{
return 0;
}
}

}

//查询的字段
if (ViewField.Length > 0)
{
query.ViewFields = BuildViewFields(ViewField);
}
//分页信息
string pageinfo = string.Format("Paged=TRUE&p_ID={0}", GetListID(listName, pageSize, curPage, strWhere,ViewField));
query.ListItemCollectionPosition = new SPListItemCollectionPosition(pageinfo);
SPListItemCollection m_objListItemColl = m_objList.GetItems(query);
return m_objListItemColl;
}
catch
{

return null;
}
}

}

}

经过5000条列表的记录测试，每次翻页加载速度为1秒多点（说明：机器为本人笔记本，虚拟机内存2.5G）
最新修改，在网友的帮助下修改的。可以按照自己实际情况来排序。
