TextBox tb;
static int i = 0;
protected void Button_Click(object sender, EventArgs e)
{
i++;
for(j=0;j<=i;j++)
{
tb = new TextBox();
tb.ID = j.ToString();
PlaceHolder1.Controls.Add(tb);
}
}
that means you need to create the added textbox again...because you are adding control dynamically to the page...
