Repeater控件的分页问题（转载）

protected System.Web.UI.WebControls.Repeater rptFramework

private void Page_Load(object sender, System.EventArgs e)

//建立DataSet
（该部分省略）

rptFramework.DataSource = myDataSet;
rptFramework.DataBind();

//将Repeater所有条目隐藏
int i = 0 ;

}

//Repeater控件的页面大小
int intPageSize = 10;

 

//rptFramework控件的当前页索引（1起始）
int intCurrentPageIndex = 0 ;

 

if ( Request.QueryString["page"] == null || Convert.ToInt32( Request.QueryString["page"] ) == 0 )
{
Session["page"] = 1 ;
}

Session["page"] = Convert.ToInt32( Request.QueryString["page"] );
}

intCurrentPageIndex = Convert.ToInt32( Session["page"] );

//上一页按钮屏蔽

//rptFramework控件的当前游标索引（1起始）
int intCurrentItemIndex = 1 ;

//下一页按钮屏蔽
