复制代码 代码如下:

}

pds.PageSize =2;
int curPage;
if (Request.QueryString["page"] != null)
{

}
else

}

}
string HtmlSelectString = "<select onchange=\"javascript:window.location=this.value\">";
for (int i = 1; i <= pds.PageCount; i++)
{
if (i == curPage)
{
//HtmlSelectString += "<option value=wjProduct-" + i + "-" + Menu_ID + ".html selected>第" + i + "页</option>";

}
else
{

HtmlSelectString += "<option value='RepeaterFENYE.aspx?page=" + i.ToString() + "'>第" + i + "页</option>";
}
}
HtmlSelectString += "</select>";
this.Label4.Text += "<a>" + HtmlSelectString + "</a>";
}
else
{
Label4.Text = "没有数据!";
}
}
}
注：//注释部分为url rewrite的效果。。。li返回的值为SQL查询后所得到表中所有的记录。。。
