Web Forms :: How To Open A New Window Using Link Button

I am trying to navigate it to another page using Link Button and in the .cs file, I am using Response.Redirect. But I want it to the open in a new window.

The reason why I cant use hyperlink is I cant use Command Arg and Command Name which I am using in the Link Button.

I tried the below Javascript, But it's coming as a pop up for the first time when it loads. I don't want it in that way also.

Is there a way like Hyperlink '_blank'.

public static void OpenNewWindow(string url, Page thispage)
{
string fullURL = "window.open('" + url + "', '_blank', 'fullscreen = no, status=yes,toolbar=yes,menubar=yes,location=yes,scrollbars=yes,resizable=yes,titlebar=yes' );";
ScriptManager.RegisterStartupScript(thispage, typeof(string), "OPEN_WINDOW", fullURL, true);
}
.cs
<asp:LinkButton ID="lbtn_photo" runat="server" Text="Upload Photo"
OnClick="Upload_Photo"></asp:LinkButton>
protected void Upload_Photo(object sender, EventArgs e)
{
Response.Redirect("UpPhoto.aspx?id=" + Request.QueryString["id"]);
}
