不同的窗口打开同一页

我使用window.open在弹出窗口中打开两个不同的页面，但由于某些原因，两个触发器都在弹出窗口打开同一页面，下面是我尝试做到这一点的方法：

第一个：

Response.Write("<script type='text/javascript'>window.open('TransEditEntry.aspx','mywindow','width=850px,height=300px,left=0,top=10,screenX=100,screenY=10')</script>");

第二：

Response.Write(@"<script type='text/javascript'>window.open('TransNewEntry.aspx','','width=850px,height=300px,left=0,top=10,screenX=100,screenY=10')</script>");

这将打开"TransEditEntry.aspx"页面，而不是"TransNewEntry.aspx`"

这里是代码的其余部分：

点击添加按钮时调用的整个功能：

protected void addNew(object sender, EventArgs e)
    {
        //HiddenField sr = (HiddenField)GridView1.SelectedRow.Cells[6].FindControl("srno");
        //Session["TransSrNo"] = sr.Value;
        Response.Write(@"<script type='text/javascript'>window.open('TransNewEntry.aspx','','width=850px,height=300px,left=0,top=10,screenX=100,screenY=10')</script>");
        //Session["transAdd"] = "1";
    }

调用函数的添加按钮：

<asp:Button ID="AddBtn" runat="server"  OnClick="addNew" Text="Add"/>

页面TransNewEntry.aspx.cs

public partial class TransEditEntry : System.Web.UI.Page
