c# 编程实现click后再弹出一窗口

private void button1_Click(object sender, EventArgs e)
{
form2 myform2 =new form2();
myform2.ShowDialog();
}

protected void Button1_Click(object sender, EventArgs e)
{
Response.Write("<script language='javascript'> window.open('panelIndex.aspx');</script>");
}

实际上就是用c# 编程 写了一段脚本
