NestedDataGrid

.aspx  1<asp:datagrid id="grdCerSeted" Width="100%" Runat="server" CssClass="DataGrid" AutoGenerateColumns="False" 2                            ShowHeader="False"> 3                            <Columns> 4<asp:TemplateColumn> 5                                    <HeaderStyle Width="0px"></HeaderStyle> 6                                    <ItemTemplate> 7                    </td> 8                </tr> 9                <tr>10                    <td colspan="5">11                        <TABLE cellSpacing="3" cellPadding="3" width="100%" border="0">12                            <TR>13                                <TD>14                                    <DIV id="divCertSetted" style="DISPLAY: inline" runat="server"><asp:datagrid id="drgSetedIntel" runat="server" Width="100%" AutoGenerateColumns="False">15                                            <Columns>16</Columns>17                                        </asp:datagrid></DIV>18                                </TD>19                            </TR>20                        </TABLE>21                        </ItemTemplate> </asp:TemplateColumn> </Columns> </asp:datagrid> 实现加减号合并展开效果  1function Toggle( commId, imageId ) 2            { 3                 4                var div = document.getElementById(commId); 5                var GetImg = document.getElementById(imageId); 6                if (document.all[commId].style.display == 'none') 7                {     8                    document.all[commId].style.display = 'block'; 9                    document.all[imageId].src = '../Images/expand.gif';10                }11                else12                {    13                    document.all[commId].style.display = 'none';14                    document.all[imageId].src = '../Images/collapse.gif';15                }16            }     外面DataGrid的ItemCreated注册里面DataGrid事件  1private void grdCerSeted_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) 2        { 3            ListItemType item = e.Item.ItemType; 4            if(item == ListItemType.Item || item == ListItemType.AlternatingItem) 5            { 6                //为包里面的DataGrid注册事件，只能手工注册，要不事件不会响应。 7                drgSetedIntel = (DataGrid)e.Item.FindControl("drgSetedIntel"); 8                if(drgSetedIntel != null) 9                {10                    drgSetedIntel.ItemDataBound +=new DataGridItemEventHandler(drgSetedIntel_ItemDataBound);    11                    drgSetedIntel.ItemCommand +=new DataGridCommandEventHandler(drgSetedIntel_ItemCommand);12                    drgSetedIntel.ItemCreated +=new DataGridItemEventHandler(drgSetedIntel_ItemCreated);13                }14            }15        } 其它用法和正常DataGrid一样了。。。
