页面刷新问题!

Question

main.aspx中<asp:DataGrid id="dataXzl" runat="server" Width="259" AutoGenerateColumns="False">
<HeaderStyle BackColor="#FCFCDE"></HeaderStyle>
<Columns>
<asp:TemplateColumn HeaderText="地址">
<ItemTemplate>
<asp:LinkButton ID="lbtnAddress" Text='<%# DataBinder.Eval(Container.DataItem,"XZAddress") %>' OnClick='lbtnAddress_Click' CommandArgument='<%# DataBinder.Eval(Container.DataItem,"Index") %>' Runat=server />
</ItemTemplate>
</asp:TemplateColumn>
<asp:BoundColumn HeaderText='地区' DataField='XZArea'></asp:BoundColumn>
<asp:BoundColumn HeaderText='信息类型' DataField='XZSell' HeaderStyle-HorizontalAlign=Center ItemStyle-HorizontalAlign=Center></asp:BoundColumn>
<asp:TemplateColumn HeaderText="发布日期">
<ItemTemplate>
<asp:Label ID="Label3" Text='<%# DateTime.Parse(DataBinder.Eval(Container.DataItem,"XZDate").ToString()).ToShortDateString() %>' ForeColor='#8080FF' Runat=server />
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:DataGrid> ------------------------------------------------------------------main.aspx.cs中public void lbtnAddress_Click(object sender, System.EventArgs e)
{
int index=Int32.Parse(((LinkButton)sender).CommandArgument);
Response.Write("<script language=javascript>window.open('../OldHouse/xzlInfo.aspx?Index="+index.ToString()+"','newwindow', 'height=320, width=455, top=150, left=300, toolbar=no, menubar=no,scrollbars=yes, resizable=no,location=no, status=no');</script>");
}这个代码为什么在谈出新窗口后主窗口会刷新啊?怎么样让它不刷新啊?
