怎么 AspNetPager 在页面上都不显示呀
------解决方案--------------------------------------------------------
AspNetPager2.RecordCount = pds.Count;
这个值必须先于数据绑定之前,并且不能和数据绑定在同一个过程中,因为分页控件要根据这个值计算总页数,把你的代码改成这样:
public void Bind()
{ AspNetPager2.RecordCount = 这里必须有实际的总记录数,不能和下面的PagedDataSource同时获取结果,这样就太迟了。
SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["Connection"]);
con.Open();
string sql = "select * from stationery where count>0";
SqlCommand com = new SqlCommand(sql, con);
SqlDataAdapter da = new SqlDataAdapter(com);
DataSet ds = new DataSet();
da.Fill(ds, "stationery");
PagedDataSource pds = new PagedDataSource();
pds.DataSource = ds.Tables[0].DefaultView;
pds.AllowPaging = true;
pds.CurrentPageIndex = AspNetPager2.CurrentPageIndex - 1;
pds.PageSize = AspNetPager2.PageSize;
this.GridView1.DataSource = pds;
this.GridView1.DataBind();
}

- C# code
string sqlSelect = "select * from News order by addtime desc"; SQLcon sl = new SQLcon(); SqlDataAdapter sda; DataSet ds = new DataSet(); sda = new SqlDataAdapter(sqlSelect, sl.Connection); sda.Fill(ds, AspNetPager1.PageSize * (AspNetPager1.CurrentPageIndex - 1), AspNetPager1.PageSize, "News"); sl.ConOpen(); AspNetPager1.RecordCount =ds.Tables.Count; if (ds.Tables[0].Rows.Count > 0) { rpNewsList.DataSource = ds.Tables["News"]; rpNewsList.DataBind(); this.divShow.Style["display"] = "none"; } else { this.divShow.Style["display"] = "block"; this.delLogRecycleBin.Enabled = false; } sl.ConClose();
