Paging - Rows in first page also showing in second page: listitemcollectionposition

Question

Hi,
I am trying to use the listitemcollectionposition to achieve paging. The pagination is shown, but some of the records in first page are getting displayed in second page as well.
I have totally 13 records in the list, and paging is applied for 10 items to show. I have set the rowcount to 10.
private void FillData(string pagingInfo)
int currentPage = Convert.ToInt32(ViewState["CurrentPage"]);
uint rowCount = 10; // Default of 10 items per page
string columnValue = string.Empty;
string nextPageString = "Paged=TRUE&p_ID={0}&p_";
string PreviousPageString = "Paged=TRUE&PagedPrev=TRUE&p_ID={0}&p_";
SPListItemCollection collection;
collection = GetTestItems(pagingInfo, rowCount);
public SPListItemCollection GetTestItems(string pagingInfo, uint rowLimit)
using (SPSite oSite = new SPSite(Sitename))
using (SPWeb oWeb = oSite.OpenWeb())
SPList lstPages = oWeb.Lists["Pages"];
SPQuery sQuery = new SPQuery();
SPListItemCollection collection;
sQuery.RowLimit = rowLimit;
sQuery.Query = "<Where>" +
"<And>" +
"<And>" +
"<Contains><FieldRef Name='PublishingPageLayout'/><Value Type='URL'>TC_NtestPageLayout.aspx</Value></Contains>" +
"<Eq><FieldRef Name='_ModerationStatus'/><Value Type='ModStat'>0</Value></Eq>" +
"</And>" +
"<Eq><FieldRef Name='_Level'/><Value Type='Integer'>1</Value></Eq>" +
"</And>" +
"</Where><OrderBy><FieldRef Name='TestLayoutDate' Ascending='FALSE' /></OrderBy>";
sQuery.ViewFields = string.Concat(
"<FieldRef Name='PublishingPageLayout' />",
"<FieldRef Name='Title' />",
"<FieldRef Name='EncodedAbsUrl' />",
"<FieldRef Name='TestLayoutDate' />");
sQuery.ViewFieldsOnly = true;
if (!string.IsNullOrEmpty(pagingInfo))
SPListItemCollectionPosition position = new SPListItemCollectionPosition(pagingInfo);
sQuery.ListItemCollectionPosition = position;
collection = lstPages.GetItems(sQuery);
return collection;
How to get the Paging properly?
Thanks

Hi,
According to your post, my understanding is that you want to display list data using a
SPGridView with Paging in a visual web part .
The following code snippet for your reference:
VisualWebPart1.ascx:
<%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>
<%@ Assembly Name="Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Register TagPrefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Register TagPrefix="Utilities" Namespace="Microsoft.SharePoint.Utilities" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Register TagPrefix="asp" Namespace="System.Web.UI" Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" %>
<%@ Import Namespace="Microsoft.SharePoint" %>
<%@ Register TagPrefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="VisualWebPart1.ascx.cs" Inherits="VisualWebPartProject3.VisualWebPart1.VisualWebPart1" %>
<SharePoint:SPGridView ID="sgvPagersample" runat="server" AutoGenerateColumns="false" DataSourceID="objSample" AllowPaging="True" PageSize="3">
<Columns>
<asp:BoundField HeaderText="Title" DataField="Title" />
<asp:BoundField HeaderText="Test1" DataField="Test1" />
<asp:BoundField HeaderText="Test2" DataField="Test2" />
</Columns>
</SharePoint:SPGridView>
<asp:ObjectDataSource ID="objSample" runat="server" SelectMethod="BindGridView"></asp:ObjectDataSource>
<center>
<SharePoint:SPGridViewPager id="sgvPager" runat="Server" GridViewId="sgvPagersample"></SharePoint:SPGridViewPager>
</center>
VisualWebPart1.ascx.cs:
using System;
using System.ComponentModel;
using System.Web.UI.WebControls.WebParts;
using System.Data;
using Microsoft.SharePoint;
namespace VisualWebPartProject3.VisualWebPart1
[ToolboxItemAttribute(false)]
public partial class VisualWebPart1 : WebPart
// Uncomment the following SecurityPermission attribute only when doing Performance Profiling using
// the Instrumentation method, and then remove the SecurityPermission attribute when the code is ready
// for production. Because the SecurityPermission attribute bypasses the security check for callers of
// your constructor, it's not recommended for production purposes.
// [System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Assert, UnmanagedCode = true)]
public VisualWebPart1()
protected override void OnInit(EventArgs e)
base.OnInit(e);
InitializeControl();
protected void Page_Load(object sender, EventArgs e)
objSample.TypeName = this.GetType().AssemblyQualifiedName;
public DataTable BindGridView()
SPWeb currentWeb = SPContext.Current.Web;
SPList lstEmployee = currentWeb.Lists["CustomList4"];
SPQuery sQuery = new SPQuery();
sQuery.Query = "<OrderBy><FieldRef Name='ID' Ascending='False' /></OrderBy>";
SPListItemCollection myColl = lstEmployee.GetItems(sQuery);
return myColl.GetDataTable();
