Dynamically Create Multiple Web User Control In a Page With Click Event Functionality

I have created a simple application having 3 user controls as

• WebUserControl1.ascx
• WebUserControl2.ascx
• WebUserControl3.ascx

Also i have a web Page as

• DynamicUserControl.aspx

First i have  created a  web user control dynamicaaly into the web page but first usercontrol event firing well but for second onwards it needed double click. Finally i got the solution if some one has better then please tell me.

Here is my First WebUsercontrol1.ascx Code:-

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl1.ascx.cs" Inherits="UserControl_WebUserControl1" %>

<%@ Reference Control="~/UserControl/WebUserControl2.ascx" %>

<asp:Button ID="Next1" runat="server" Text="Next" onclick="Next1_Click" />

WebUsercontrol1.ascx.cs Code:-

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

    public partial class UserControl_WebUserControl1 : System.Web.UI.UserControl

    {

        public event EventHandler Next1Click;

        protected void Page_Load(object sender, EventArgs e)

        {

            

        }

        protected void Next1_Click(object sender, EventArgs e)

        { 

            Session["test"] = "2";

            Next1Click(sender, e);

            UserControl_WebUserControl2 ucSimpleControl = (UserControl_WebUserControl2)LoadControl("~/UserControl/WebUserControl2.ascx");

            PlaceHolder phContactDetails = (PlaceHolder)Page.FindControl("ControlHolder");

            phContactDetails.Controls.Clear();

            phContactDetails.Controls.Add(ucSimpleControl);

            ucSimpleControl.Next2Click += new EventHandler(ucSimpleControl_Next2Click);

          

        }

        protected void ucSimpleControl_Next2Click(object sender, EventArgs e)

        {

            Response.Write("It's working");

        }

    }

Here is my second WebUsercontrol2.ascx Code:-

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl2.ascx.cs" Inherits="UserControl_WebUserControl2" %>
<%@ Reference Control="~/UserControl/WebUserControl3.ascx" %>
<asp:Button ID="Next2" runat="server" Text="Next2" onclick="Next2_Click" />

WebUsercontrol2.ascx.cs Code:-

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

  public partial class UserControl_WebUserControl2 : System.Web.UI.UserControl

    {

        public event EventHandler Next2Click;

       

        protected void Page_Load(object sender, EventArgs e)

        {

           

        }

        protected void Next2_Click(object sender, EventArgs e)

        { 

            Session["test"] = "3";

            Next2Click(sender, e);

            UserControl_WebUserControl3 ucSimpleControl = (UserControl_WebUserControl3)LoadControl("~/UserControl/WebUserControl3.ascx");

            PlaceHolder phContactDetails = (PlaceHolder)Page.FindControl("ControlHolder");

            phContactDetails.Controls.Clear();

            phContactDetails.Controls.Add(ucSimpleControl);

            ucSimpleControl.Next3Click += new EventHandler(ucSimpleControl_Next3Click);

           

        }

        protected void ucSimpleControl_Next3Click(object sender, EventArgs e)

        {

            Response.Write("It's working");

        }

        

    }

Here is my Third WebUsercontrol3.ascx Code:-

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl3.ascx.cs" Inherits="UserControl_WebUserControl3" %>
<asp:Button ID="Next3" runat="server" Text="Next3" onclick="Next3_Click" />

WebUsercontrol3.ascx.cs Code:-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;




    public partial class UserControl_WebUserControl3 : System.Web.UI.UserControl
    {
        public event EventHandler Next3Click;
        protected void Page_Load(object sender, EventArgs e)
        {
            
        }
        protected void Next3_Click(object sender, EventArgs e)
        {
            Next3Click(sender, e);
          
        }
        
    }

Finally This is my DynamicUserControl.aspx:-

Source Code:-

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="DynamicUserControl.aspx.cs" Inherits="DynamicUserControl" %>

<%@ Reference Control="~/UserControl/WebUserControl1.ascx" %>

<%@ Reference Control="~/UserControl/WebUserControl2.ascx" %>

<%@ Reference Control="~/UserControl/WebUserControl3.ascx" %>

<%@ Register Src="~/UserControl/WebUserControl1.ascx" TagName="FirstControl" TagPrefix="gis" %>

My Code Behind:-

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

public partial class DynamicUserControl : System.Web.UI.Page

{

   

    protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            Session["test"] = null;

        }

        int id = 1;

        int i=0;

        if (Session["test"] != null)

        {

           

            id = int.Parse(Session["test"].ToString());

        

        }

        if (Session["test"] == null)

        {

            UserControl_WebUserControl1 ucSimpleControl = (UserControl_WebUserControl1)LoadControl("~/UserControl/WebUserControl" + id + ".ascx");

            ControlHolder.Controls.Clear();

            ControlHolder.Controls.Add(ucSimpleControl);

            ucSimpleControl.Next1Click += new EventHandler(ucSimpleControl_Next1Click);

        }

        if (id == 2)

        {

            UserControl_WebUserControl2 ucSimpleControl = null;

           

                ucSimpleControl = (UserControl_WebUserControl2)LoadControl("~/UserControl/WebUserControl" + id + ".ascx");

            

                ControlHolder.Controls.Clear();

                for (i = 1; i <= id; i++)

                {

            ControlHolder.Controls.Add(ucSimpleControl);

                }

            ucSimpleControl.Next2Click += new EventHandler(ucSimpleControl_Next2Click);

        }

        

        if (id == 3)

        {

            UserControl_WebUserControl3 ucSimpleControl=null;

           

             ucSimpleControl = (UserControl_WebUserControl3)LoadControl("~/UserControl/WebUserControl" + id + ".ascx");

            

            ControlHolder.Controls.Clear();

            for (i = 1; i <= id; i++)

            {

            ControlHolder.Controls.Add(ucSimpleControl);

            } 

                ucSimpleControl.Next3Click += new EventHandler(ucSimpleControl_Next3Click);

          

        }

       

            

            

        

    }

    

    protected void ucSimpleControl_Next1Click(object sender, EventArgs e)

    {

        

        Response.Write("The First usercontrol working fine");

    }

    protected void ucSimpleControl_Next2Click(object sender, EventArgs e)

    {

        Response.Write("The Second usercontrol working fine");

    }

    protected void ucSimpleControl_Next3Click(object sender, EventArgs e)

    {

        Response.Write("The Third usercontrol working fine");

    }

   

}

The Screen Shot of my Folder and user control is : 

This is working fine but i need some optimisation way.if any one then let me know.
