Repeater control:
The Repeater control is used to display the data items in representing list.
The content and layout of list items in Repeater is defined using Templates.
Every Repeater must define an ItemTemplate.
Template:
There are the following Templates used in repeater control.
AlternatingItemTemplate FooterTemplate HeaderTemplate
ItemTemplate SeparatorTemplate
FooterTemplate: The FooterTemplate determines the content and layout of the
list footer. It is used to specify an optional footer row.
For Example:
<FooterTemplate></table></FooterTemplate>
HeaderTemplate: The HeaderTemplate determines the content and layout of the
list header. It is used to specify an optional header row.
For Example:
<HeaderTemplate>
<tr>
<td><b>Roll no</b></td>
<td><b>Name</b></td>
<td><b>Course</b></td>
</tr>
</HeaderTemplate>
ItemTemplate: It defines the content and layout of items within the list.
For Example:
<ItemTemplate>
<tr>
<td><%# DataBinder.Eval(Container,"dataitem.Roll no") %></td>
<td><%# DataBinder.Eval(Container,"dataitem.Name") %></td>
<td><%# DataBinder.Eval(Container,"dataitem.Course") %></td>
</tr>
</ItemTemplate>
AlternatingItemTemplate: It is used as follows:
For Example:
<AlternatingItemTemplate>
<tr style="background-color:Yellow">
<td><%# DataBinder.Eval(Container,"dataitem.Roll no") %></td>
<td><%# DataBinder.Eval(Container,"dataitem.Name") %></td>
<td><%# DataBinder.Eval(Container,"dataitem.Course") %></td>
</tr>
</AlternatingItemTemplate>
SeparatorTemplate: The SeparatorTemplate is rendered between items (and
alternating items).
Repeater has no built-in layout or styles. You must explicitly declare all HTML
layout, formatting, and style tags within the templates of the control.
In the following section you will learn how you can access data into Repeater
control from DataBase.
For Example:
To create a list within an HTML table, you might declare the <table> tag in the
HeaderTemplate, a table row in the ItemTemplate, and the </table> tag in the
FooterTemplate as follows-
Default.aspx file:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs"
Inherits="_Default" Debug="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml"; >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Repeater ID="Repeater1" runat="server"
OnItemCommand="repeater1_itemcomand">
<HeaderTemplate>
<table border=5>
<tr>
<td><b>Roll no</b></td>
<td><b>Name</b></td>
<td><b>Course</b></td>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><%# DataBinder.Eval(Container,"DataItem.Rollno") %></td>
<td><%# DataBinder.Eval(Container,"dataitem.Name") %></td>
<td><%# DataBinder.Eval(Container,"dataitem.Course") %></td>
</tr>
</ItemTemplate>
<AlternatingItemTemplate>
<tr style="background-color:Yellow">
<td><%# DataBinder.Eval(Container,"dataitem.Rollno") %></td>
<td><%# DataBinder.Eval(Container,"dataitem.Name") %></td>
<td><%# DataBinder.Eval(Container,"dataitem.Course") %></td>
</tr>
</AlternatingItemTemplate>
<FooterTemplate></table></FooterTemplate>
</asp:Repeater>
</div>
</form>
</body>
</html>
We write the code on page load to access the table.
Default.aspx.cs:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
SqlConnection con;
SqlCommand com = new SqlCommand();
protected void Page_Load(object sender, EventArgs e)
{
con = new SqlConnection("Data Source=MCN004;Initial Catalog=student;
uid=sa;pwd=");
com.Connection = con;
com.CommandText = "select * from student";
con.Open();
Repeater1.DataSource= com.ExecuteReader();
Repeater1.DataBind();
con.Close();
}
protected void repeater1_itemcomand(object source, RepeaterCommandEventArgs
e)
{}
}
