Hi,
Try this out:

C#

Button btnDyn;
Label lbl;

protected void Page_Init(object sender, EventArgs e)
{
    btnDyn = new Button();
    btnDyn.ID = "btnDyn";
    btnDyn.Style["Position"] = "Absolute";
    btnDyn.Style["Top"] = "100px";
    btnDyn.Style["Left"] = "10px";
    btnDyn.Click += new EventHandler(Button_Click);
    this.form1.Controls.Add(btnDyn);
 
    lbl = new Label();
    lbl.ID = "lblDyn";
    lbl.Style["Position"] = "Absolute";
    lbl.Style["Top"] = "150px";
    lbl.Style["Left"] = "10px";
    this.form1.Controls.Add(lbl);
}

protected void Page_Load(object sender, EventArgs e)
{
    btnDyn.Text = "Dynamic Button";
    lbl.Text = "";
}

protected void Button_Click(object sender, EventArgs e)
{
    lbl.Text = "dynamic label text";
}

C#

public void createbuttons()
   {
       for (int i = 2; i <= 5; i++)
       {
           Button b = new Button();
           b.ID = "Button"+i.ToString();
           b.Text = "Button"+ i.ToString();
           b.Click += new EventHandler(b_Click);
           this.form1.Controls.Add(b);
           Panel1.Controls.Add(b);
       }

Write this where you want to call click event.
b.Click += this.b_Click;

Put dis link button creation code in Page load with out

if (!Page.IsPostBack)

and write handler for it
This will work

LinkButton lbtnDownload = new LinkButton();
                  lbtnDownload.Click += new System.EventHandler(lbtnDownlaod_Click);
                  lbtnDownload.Text = "Downlaod Here";
                  Div.Controls.Add(lbtnDownload);

 private void lbtnDownlaod_OnClick(object sender, EventArgs e)
        {
//Your code here 
}
