GridView分頁(yè)的實(shí)現(xiàn)以及自定義分頁(yè)樣式功能實(shí)例

要在GridView中加入
//實(shí)現(xiàn)分頁(yè)
AllowPaging="true"
//一頁(yè)數(shù)據(jù)10行
PageSize="10"
// 分頁(yè)時(shí)觸發(fā)的事件
OnPageIndexChanging="gvwDesignationName_PageIndexChanging"

protectedvoid gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvwDesignationName.PageIndex=e.newIndex;
bingDesignatioonName();
}
