DbEntry采用分页技术显示数据在GridView里面并用AspNetPager控件来显示分页

1.后台代码

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                RefreshViewer(1);
            }
        }
        private void RefreshViewer(int NewIndex)
        {
            var ps = DbEntry
                .From<User>()
                .Where(Condition.Empty)
                .OrderBy((DESC)"Id")
                .PageSize(20)
                .GetPagedSelector();
            var count = ps.GetResultCount();

            //Aspnetpager1 Properties Setting
            AspNetPager1.RecordCount = Convert.ToInt32(count);
            AspNetPager1.PageSize = 20;
            AspNetPager1.UrlPaging = true;

            NewIndex = NewIndex < 1 ? 1 : NewIndex;
            //GridView Properties Setting
            this.GridView1.PageSize = 20;
            GridView1.DataKeyNames = new string[] { "Id"};
            GridView1.PageIndex = NewIndex;
            GridView1.DataSource = ps.GetCurrentPage(NewIndex-1);
            GridView1.DataBind();
        }

        protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e)
        {
            RefreshViewer(e.NewPageIndex);
        }

        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            //Add Confirm messaged
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                 if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
                {
                    ((LinkButton)e.Row.Cells[2].Controls[0]).Attributes.Add("onclick",
                        "javascript:return confirm('你确认要删除:"+ e.Row.Cells[1].Text + "吗?')");
                }
            }
            //Change Rows Mouceover and Mouceout Color 
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
                e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
            }
        }

        protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
        {
            string id = GridView1.DataKeys[e.RowIndex].Value.ToString()+"";
            User o = User.FindById(1);
            o.Delete();

        }
