Hi friends,
In my application i want to generate dynamic textboxes and a button.And in that dynamically generated button click i need to generate another set of dynamic textbox and button.How to get the event of the dynamic button.I tried several ways,like adding click event dynamically when it is generated.But the problem is that when i click on the dynamic button the page get refreshed.The dynamic generated textbox and button disappeared.My code is as follows

protected void Button1_Click(object sender, EventArgs e)
{
int cnt = int.Parse(TextBox1.Text.ToString());

TableRow tr = new TableRow();
TableCell td = new TableCell();
for (int j = 1; j <= cnt; j++)
{

TextBox txt = new TextBox();
txt.ID = "txt" + j.ToString();
td.Controls.Add(txt);
}
Button btn = new Button();
btn.ID = "btn1";
btn.Text = "ADD";
btn.CommandArgument = "1";
btn.Click += new EventHandler(MyButtonClick);
td.Controls.Add(btn);
tr.Cells.Add(td);
tr.VerticalAlign = VerticalAlign.Top;

tbldyanamic.Rows.Add(tr);

}
private void MyButtonClick(object sender, System.EventArgs e)
{
if (!IsPostBack)
{
string buttonID = ((Button)sender).ID;
}
// DO SOMETHING
}
Plz help me to solve this problem.

Add the control in page_preload & also add the handler in the page_preload.
