                        ForeColor="#333333" GridLines="None" OnRowDataBound="GridView3_RowDataBound" 
                        PageSize="20">
                        <Columns>
                           
                            <asp:BoundField DataField="FHSL" HeaderText="符合数量" />
                            <asp:BoundField DataField="BZ" HeaderText="备注" />
                            <asp:TemplateField>
                                <ItemTemplate>
                                    <asp:DropDownList ID="DropDownList3" runat="server" OnSelectedIndexChanged="DropDownList3_SelectedIndexChanged" AutoPostBack="true">
                                       <asp:ListItem>请选择</asp:ListItem>
                                        <asp:ListItem>借出</asp:ListItem>
                                        <asp:ListItem>租出</asp:ListItem>
                                        <asp:ListItem>毁损</asp:ListItem>
                                       <asp:ListItem>盘亏</asp:ListItem>
                                    </asp:DropDownList>
                                </ItemTemplate>
                                <HeaderTemplate>
                                    <asp:Label ID="Label21" runat="server" Text="盘点未见原因"></asp:Label>
                                </HeaderTemplate>
                            </asp:TemplateField>
                        </Columns>
                        <PagerSettings Visible="False" />
                        <RowStyle BackColor="white" HorizontalAlign="Left" />
                        <FooterStyle BackColor="#7799CC" Font-Bold="True" ForeColor="White" />
                        <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
                        <HeaderStyle BackColor="#507CD1" Font-Bold="True" Font-Size="Large" 
                            ForeColor="White" />
                        <AlternatingRowStyle BackColor="White" />
                    </asp:GridView>

后台获取行索引：

 protected void DropDownList3_SelectedIndexChanged(object sender, EventArgs e)
    {
        
        int i;
        var dropDown = sender as DropDownList;
        TableCell cell = null;
        if (dropDown != null)
        {
            cell = dropDown.Parent as TableCell;
            var row = cell.Parent as GridViewRow;
            i = row.RowIndex;
           string  guid = GridView3.Rows[i].Cells[1].Text;//获取当前行的guid
            if (dropDown.SelectedValue == "借出")
            {
                Response.Write(" <script   language=javascript> window.open   ( 'jc.aspx?guid=" + guid + "&dw=" + dw + " ',  '借出信息表',   'height=320,   width=700,   top=200,left=270,   toolbar=no,   menubar=no,   scrollbars=no,   resizable=no,  location=no,   status=no ') </script> ");

            }
           

        }
   
        
    }
