Below sample code will add a button on runtime in you web page. Modify it to meet your requirements.

C#

private void AddButton(int id)
{
//Initialize button and set its properties (especially ID)
Button bt = new Button();
bt.ID = "btn" + id.ToString();
bt.Text = "Text"+id.ToString();
//Attach click event
bt.Click += new EventHandler(bt_click);
//Change below line (this) with the container in which you want your button to appear.
this.Controls.Add(bt);
}

Click event handler will be:

C#

protected void bt_click(object sender, EventArgs e)
{
    Button btn = sender as Button;
    //Add your functionality here
}

I did not get you. What do you exactly mean by swaping? and swap button with what? can you explain the requirement a bit more clearly.

i am create a puzzle game 24 button swap random button one location to other location (ex. i m select button one is swap with button 2) so now i m create a dynamic button and also create dynamic click event but button was not swap so what can i do ...

I dint get what exactly you are trying to achieve.

However, if you just want to change the numbers written on button, then you can set the bt.Text property on runtime by swapping it with the other button's number. By doing this you are not actually swapping the entire button but only the text written on it.

Add panel to your page..

C#

public partial class WebForm1 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Table tb = new Table();

        for (int i = 0; i < 5; i++)
        {
            TableRow tr = new TableRow();

            for (int j = 0; j < 5; j++)
            {
                TableCell tc = new TableCell();
                Button bt = new Button();
                bt.Height = 10;
                bt.Width = 10;
                tc.Controls.Add(bt);
                bt.Click += bt_Click;
                tr.Cells.Add(tc);

            }

            tb.Rows.Add(tr);
        }

      Panel1  .Controls.Add(tb);
    }

    void bt_Click(object sender, EventArgs e)
    {
        Response.Write("hello");
    }
}

protected void Page_Load(object sender, EventArgs e)
{

Table tbl = new Table();
phl.Controls.Add(tbl);
Array array = new Array[25];
Random rndm = new Random();
int n = rndm.Next();
string[] a = new string[25];

for (int i = 0; i < 5; i++)
{

TableRow tbr = new TableRow();
for (int j = 0; j < 5; j++)
{
TableCell tbcl = new TableCell();
Button bt = new Button();
ListItem ls = new ListItem();
ls.Text.Contains(ls.Text);
bt.Text = ls.Text;
ListBox lb = new ListBox();
lb.Items.Add(ls);
ls.Text = rndm.Next(1, 25).ToString();

tbcl.Controls.Add(bt);

tbr.Cells.Add(tbcl);

}

}
}
}
}
