respose.Redirect也有打开目标

protected void Page_Load(object sender, EventArgs e)
    {
        Button1.Attributes.Add("onclick", "this.form.target='_newName'");
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Redirect("http://dotnet.aspx.cc/");
    }


protected void Page_Load(object sender, EventArgs e)
    {
        Button1.Attributes.Add("onclick", "this.form.target='_newName'");
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Redirect("http://dotnet.aspx.cc/");
    }

如果需要设置弹出窗口的宽度和高度
   protected void Page_Load(object sender, EventArgs e)
    {
      string WindowName = "win" + System.DateTime.Now.Ticks.ToString();
      Page.RegisterOnSubmitStatement("js", "window.open('','" + WindowName + "','width=600,height=200')");
        form1.Target = WindowName;
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Redirect("http://dotnet.aspx.cc/");
    }
