Pagination in asp.net Listview control using Datapager

Introduction: In this article I will explain how to implement the paging in asp.net listview control using datapager without using datasource control

Description:
To implement this functionality add a webform to project. Drag and drop the listview and datapager control from toolbox to webform.

HTML markup of webpage:
    <table>
    <tr><td>
        <asp:ListView ID="ListView1" runat="server"
            onpagepropertieschanging="ListView1_PagePropertiesChanging">
        <LayoutTemplate>        
        <table>
  <tr>
  <th>Student Name</th>
  <th>Student Address</th>
  <th>Student Class</th> 
     </tr>
    <tr id="itemPlaceholder" runat="server"></tr>
        </LayoutTemplate>
        <ItemTemplate>
         <tr align="center">
       <td> <asp:Label ID="lblstudentname" runat="server" Text='<%#Eval("Student_Name")%>'></asp:Label></td>
         <td><asp:Label ID="lbladdress" runat="server" Text='<%#Eval("Student_Address") %>'></asp:Label></td>
          <td><asp:Label ID="lblroll" runat="server" Text='<%#Eval("RollNo") %>'></asp:Label></td>
</tr>
        </ItemTemplate>     
        </asp:ListView>
        </td></tr>
        <tr><td></td></tr>
        <tr><td><asp:DataPager ID="DataPager1" runat="server" PagedControlID="ListView1" PageSize="3">
        <Fields><asp:NextPreviousPagerField ButtonType="Link" ShowFirstPageButton="false" ShowPreviousPageButton="true"
                            ShowNextPageButton="false" />
                        <asp:NumericPagerField ButtonType="Link" />
                        <asp:NextPreviousPagerField ButtonType="Link" ShowNextPageButton="true" ShowLastPageButton="false" ShowPreviousPageButton = "false" />
                    </Fields>
        </asp:DataPager></td></tr>
        </table> 

After that write the code to bind the listview.
Add the namespaces
C#:-
using System.Data;
using System.Data.SqlClient;
using System.Configuration;

VB:-
Imports System.Data
Imports System.Data.SqlClient
Imports System.Configuration

Create a connection.
C#:-
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ToString());

VB:-
Private con As New SqlConnection(ConfigurationManager.ConnectionStrings("connection").ToString())

Write the code to bind the listview
C#:-
protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Bindlist();
        }
    }
    public void Bindlist()
    {
        SqlDataAdapter adp = new SqlDataAdapter("Select * from Tb_Student", con);
        DataTable dt = new DataTable();
        adp.Fill(dt);
        if (dt.Rows.Count > 0)
        {
            ListView1.DataSource = dt;
            ListView1.DataBind();
        }
    }  

VB:-
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            Bindlist()
        End If
    End Sub
    Public Sub Bindlist()
        Dim adp As New SqlDataAdapter("Select * from Tb_Student", con)
        Dim dt As New DataTable()
        adp.Fill(dt)
        If dt.Rows.Count > 0 Then
            ListView1.DataSource = dt
            ListView1.DataBind()
        End If
    End Sub

When page is changed onpagepropertieschanging event is triggered. So we write the code on this event to implement the paging.
C#:-
protected void ListView1_PagePropertiesChanging(object sender, PagePropertiesChangingEventArgs e)
    {
        DataPager1.SetPageProperties(e.StartRowIndex, e.MaximumRows, false);
        Bindlist();
    }
 VB:-
Protected Sub ListView1_PagePropertiesChanging(sender As Object, e As System.Web.UI.WebControls.PagePropertiesChangingEventArgs) Handles ListView1.PagePropertiesChanging
        DataPager1.SetPageProperties(e.StartRowIndex, e.MaximumRows, False)
        Bindlist()
    End Sub

Build, run the project and see the result.
Result:-
Pagination in asp.net Listview control using Datapager

In this article we have learn how to implement the pagination in asp.net listview control using datapager without using datasource control (C#,VB). I hope you enjoyed this article.
