翻页后继续维持排序物业

要想实现翻页后继续排序,实现这样的效果:

比如共 15笔记录，每页显示10条

则排序时:第一页将前10条记录排序，翻第二页时后五条再单独排序.

要注意以下几点:

1.如果数据很多,最好不要把数据集放到缓存中(viewstate),影响性能

2. ViewState中存放上次是哪个pression并且存放此pression是升序还是降序

示例如下:

1.现有的排序事件是这样写的,这个是点击上面排序标题时用:

private void grdProjTrace_SortCommand(object source, DataGridSortCommandEventArgs e)

{

rrentPageIndex = 0;

DataView dv = 得到数据代码;

string strSort = \"\";

string strOrder =\"\";//排序方式。0，降序，1升序

if(ViewState[\"SortExpresstion\"] != null)

{

strSort = ViewState[\"SortExpresstion\"].ToString();

strSort = bstring(0,ngth -1);

strOrder = ViewState[\"SortExpresstion\"].ToString();

strOrder = bstring(ngth -1);

}

if(rtExpression == \"CustomerName\")

{

if(strSort != \"CustomerName\")

{

ewState[\"SortExpresstion\"] = ustomerName0\";

rt = \"CustomerName DESC\";

}

else

{

if(strOrder == \"0\")

{

ewState[\"SortExpresstion\"] = \"CustomerName1\";

rt = \"CustomerName ASC\";

}

else

{

ewState[\"SortExpresstion\"] = \"CustomerName0\";

rt = \"CustomerName DESC\";

}

}

}

if(rtExpression == \"fullName\")

{

if(strSort != \"fullName\")

{

ewState[\"SortExpresstion\"] = \"fullName0\";

rt = \"fullName DESC\";

}

else

{

if(strOrder == \"0\")

{

ewState[\"SortExpresstion\"] = \"fullName1\";

rt = \"fullName ASC\";

}

else

{

ewState[\"SortExpresstion\"] = \"fullName0\";

rt = \"fullName DESC\";

}

}

}

中国男力士在这两场比赛中都尽了全力。吴景彪最后一举险些受伤 taSource = dv;

taBind();
