我想知道有没有办法在ASPXGridview上实现无休止的滚动。我见过这样的事情(http://demos.devexpress.com/aspxgridviewdemos/PagingAndScrolling/EndlessPaging.aspx),但这不起作用,因为我有一个旧版本的DevExpress。
我的网格包含大量数据,因此我不希望它一次性加载。
这可以使用JQuery完成吗?
这是我填充结果网格的代码:
public List<main_screenHelper> GetDedicatedRouteList(string SwitchCd, int AccId, int BndId, int CarrId, int SttId, int StatusId, int Req_id)
{
SqlConnection con = ConnectionFactory.GetDedicatedRoutesConnection();
SqlCommand cmd = new SqlCommand("GetDedicatedRoutesList", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@SwitchCd", SwitchCd);
cmd.Parameters.AddWithValue("@AccId", AccId);
cmd.Parameters.AddWithValue("@BndId", BndId);
cmd.Parameters.AddWithValue("@CarrId", CarrId);
cmd.Parameters.AddWithValue("@SttId", SttId);
cmd.Parameters.AddWithValue("@StatusId", StatusId);
cmd.Parameters.AddWithValue("@Req_id", Req_id);
List<main_screenHelper> dedicatedRoutList = new List<main_screenHelper>();
try
{
con.Open();
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
main_screenHelper drList = new main_screenHelper();
drList.dr_id = Int32.Parse(dr["dr_id"].ToString());
drList.switch_code = (dr["switch_code"].ToString());
drList.cus_company_name = (dr["cus_company_name"].ToString());
drList.carrier = (dr["Carrier"].ToString());
drList.dr_percentage = Int32.Parse(dr["dr_percentage"].ToString());
drList.dr_overflow = (dr["dr_overflow"].ToString());
drList.bnd_name = (dr["bnd_name"].ToString());
drList.RoutingCase = (dr["RoutingCase"].ToString());
drList.peak = Convert.ToBoolean(dr["peak"]);
drList.off_peak = Convert.ToBoolean(dr["off_peak"]);
drList.weekend = Convert.ToBoolean(dr["weekend"]);
drList.active_date = Convert.ToDateTime(dr["active_date"]);
drList.stt_name = (dr["stt_name"].ToString());
drList.stt_display_order = Int32.Parse(dr["stt_display_order"].ToString());
drList.opportunity = Convert.ToBoolean(dr["opportunity"]);
drList.Lock = Convert.ToBoolean(dr["lock"]);
drList.comments = (dr["comments"].ToString());
drList.lcr_name = (dr["lcr_name"].ToString());
dedicatedRoutList.Add(drList);
}
}
finally
{
con.Close();
con = null;
cmd = null;
}
return dedicatedRoutList;
}
}
这是我的网格ASP代码:

我没有完整的答案,但希望能把你带到正确的方向。
我认为您可以通过将DevExpress GridView与jQuery结合使用来模仿无限滚动的行为,但这需要一些努力。 您可以使用GridView定义一个可滚动的div,让jQuery检测您是否在底部附近滚动。 看到: Check if a user has scrolled to the bottom
如果jQuery事件触发,您可以在ASPxGridView上执行自定义回调,请选择几个额外的行并将它们绑定到您的网格。
升级DevExpress许可证或使用默认分页可能更容易:)
