In
this article I will explain How to enable the pagination (paging) in Gridview
control in Asp.net.
Description:
In
the previous article I have explained Set number of rows to display in Gridviewaccording to Dropdown Selection in Asp.net and How to protect the content andimages from theft using JavaScript and CSS
Gridview
control has the in-built paging functionality. To enable it we have to set the AllowPaging property to true to enable
pagination and handle the OnPageIndexChanging
event. When we set the AllowPaging property to true by default Numeric paging mode
will work. We can customize the paging mode by setting the property PagerSettings-Mode of Gridview. We have four options NextPrevious, NextPreviousFirstLast,
Numeric and NumericFirstLast. Don’t
forget to assign the Pagesize.
Implementation:
HTML
Markup of Webform:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" AllowPaging="true" PageSize="5" OnPageIndexChanging="GridView1_PageIndexChanging">
<Columns>
<asp:BoundField DataField="SudentName" HeaderText="Name" />
<asp:BoundField DataField="Fee" HeaderText="Fee" />
<asp:BoundField DataField="StudentClass" HeaderText="Class" />
<asp:BoundField DataField="StudentRollNo" HeaderText="Roll Number" />
</Columns>
</asp:GridView>
Example
of Gridview Markup with PagerSettings-Mode:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" AllowPaging="true" PagerSettings-Mode="NextPrevious" PagerSettings-PreviousPageText="Previous" PagerSettings-NextPageText="Next" PagerSettings-FirstPageText="First" PagerSettings-LastPageText="Last" PageSize="5" OnPageIndexChanging="GridView1_PageIndexChanging">
<Columns>
<asp:BoundField DataField="SudentName" HeaderText="Name" />
<asp:BoundField DataField="Fee" HeaderText="Fee" />
<asp:BoundField DataField="StudentClass" HeaderText="Class" />
<asp:BoundField DataField="StudentRollNo" HeaderText="Roll Number" />
</Columns>
</asp:GridView>
Add
the namespace
C#:
using System.Data;
using System.Data.SqlClient;
using
System.Configuration;
VB:
Imports System.Data
Imports System.Data.SqlClient
Imports
System.Configuration
Write
the code to bind the Gridview from database
C#:
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ToString());
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
BindGridview();
}
}
public void BindGridview()
{
try
{
SqlDataAdapter adp = new SqlDataAdapter("Select * from
dbo.Student_Detail", con);
DataTable dt = new DataTable();
adp.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
}
catch(Exception ex)
{
}
}
VB:
Private con As New SqlConnection(ConfigurationManager.ConnectionStrings("connection").ToString())
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
If Not IsPostBack Then
BindGridview()
End If
End Sub
Public Sub BindGridview()
Try
Dim adp As New SqlDataAdapter("Select * from
dbo.Student_Detail", con)
Dim dt As New DataTable()
adp.Fill(dt)
GridView1.DataSource = dt
GridView1.DataBind()
Catch ex As Exception
End Try
End Sub
After
that write the below given code on PageIndexChanging event of Gridview.
C#:
protected void
GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
BindGridview();
}
VB:
Protected Sub
GridView1_PageIndexChanging(sender As Object, e As GridViewPageEventArgs) Handles GridView1.PageIndexChanging
GridView1.PageIndex = e.NewPageIndex
BindGridview()
End Sub
Now
build, run the project.
Result:
In this article we have learn How to enable the pagination (paging) in Gridview control in Asp.net using (C#, VB). I hope you enjoyed this article.
