Repeater Control in ASP.Net

The Repeater control is used to display a repeated list of items that are bound to the control.

The Repeater control allows you to create templates to define the layout of its content. The templates are:

·         ItemTemplate - Use this template for elements that are rendered once per row of data.

·         AlternatingItemTemplate - Use this template for elements that are rendered every other row of data. This allows you to alternate background colors, for example.

·         HeaderTemplate - Use this template for elements that you want to render once before your ItemTemplate section.

·         FooterTemplate - Use this template for elements that you want to render once after your ItemTemplate section.

·         SeperatorTemplate - Use this template for elements to render between each row, such as line breaks.

 

<asp:Repeater ID="Repeater1" runat="server">

Repeater Control in ASP.Net

BindData:

protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            Binddata();

        }

 

    }

    public void Binddata()

    {

        DataSet ds = new DataSet();

 

        Repeater1.DataSource = Class1.execute_fill_repeater("insert_reg");

        Repeater1.DataBind();

 

    }

In above code execute_fill_repeater is a function created in Class1.cs which is described below.

And insert_reg is a stored procedure made in backend.Which is described below

Repeater Control in ASP.Net

Add both namespace in every .cs page in which you want to use data and SQL related keyword

using System.Data;

using System.Data.SqlClient;

Class1.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Data.SqlClient;

using System.Data;

using System.Web;

 

public class Class1

{

     

    public static DataSet execute_fill_ repeater(string spname)// this function is used to bind data

    {

        SqlConnection con = Connection.CreateConnection();

        DataSet ds = new DataSet();

        SqlCommand cmd = new SqlCommand();

        cmd.CommandText = spname;

        cmd.CommandType = CommandType.StoredProcedure;

        cmd.Connection = con;

        con.Open();

 

        SqlDataAdapter da = new SqlDataAdapter(spname, con);

        da.Fill(ds);

 

        return ds;

    }

}

 

In class1.cs  Connection keyword is used

Connection is class in whichCreateConnection function is created.

Connection.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Configuration;

using System.Web;

using System.Data;

using System.Data.SqlClient;

 

public class Connection

{

 

    public static SqlConnection CreateConnection()

    {

        string connectionstring;

        connectionstring = ConfigurationManager.ConnectionStrings["mycon"].ConnectionString;

        SqlConnection sqlcon = new SqlConnection(connectionstring);

        return sqlcon;

    }

 

   

}

 

mycon is connection object created in web.config

web.config:

<connectionStrings>

            <add name="mycon"connectionString="Data Source=(local);Initial Catalog=my; User Id=sa; Password=sa"providerName="System.Data.SqlClient"/>

      </connectionStrings>

Write this connection string above <system.web>

Stored procedure:

This procedure is used to select data

Create procedure insert_reg

 

as

begin

select * from regform

end
