asp.net datagrid中点击弹出detail窗口,为什么主窗口显示[object]?

[interbanker]

大家好我学习ASP.NET时间不长,有个问题解决不了，希望大家帮忙看看,谢谢了.
Datagrid的代码如下:
<asp:DataGrid id="dgvideo" runat="server" BackColor="White" Width="313px" AutoGenerateColumns="False" AllowPaging="True" BorderColor="White" BorderStyle="Ridge" CellSpacing="1" BorderWidth="2px"CellPadding="3" GridLines="None">
<SelectedItemStyle Font-Bold="True" ForeColor="White" BackColor="#9471DE"></SelectedItemStyle>
<Columns>
<asp:HyperLinkColumn DataNavigateUrlField="videoid" DataNavigateUrlFormatString="javascript:varwin=window.open('modifymovie.aspx?videoid={0}',null,'width=692,height=25');"
DataTextField="videoname" SortExpression="videoname" HeaderText="名称" DataTextFormatString="{0:c}"></asp:HyperLinkColumn>
<asp:ButtonColumn Text="删除" CommandName="Delete"></asp:ButtonColumn>
</Columns>
<PagerStyle NextPageText="下一页" PrevPageText="上一页" HorizontalAlign="Right" ForeColor="Black"BackColor="#C6C3C6"></PagerStyle>
</asp:DataGrid></FONT></DIV>
运行后了,点击后，弹出新窗口，但是父窗口显示[object],不知道是为什么，请哪位高手指点下.谢谢了.!

把你这段代码<asp:HyperLinkColumn DataNavigateUrlField="videoid" DataNavigateUrlFormatString="javascript:varwin=window.open('modifymovie.aspx?videoid={0}',null,'width=692,height=25');"
改为：

<asp:HyperLinkColumn DataNavigateUrlField="videoid" Target="_blank" DataNavigateUrlFormatString="javascript:varwin=window.open('modifymovie.aspx?videoid={0}',null,'width=692,height=25');window.close（）;"

即可。
关键点两点：Target="_blank" ， window.close（）;

注意把上面的（）改为()
