我需要向我的RadGrid实例添加多个页脚行；不过，目前我只想添加第二个。我目前有一个页脚行，它正在完美地工作和显示，以供记录。

我在 Telerik 论坛上找到了以下相关问题并尝试实现它，但它不起作用：代码被执行，新代码FooterItem被添加到第二行，Controls但第二行没有出现。我需要找出原因，如果有人能帮我解决这个问题，我将不胜感激。

后面的相关代码

    protected void RadGrid1_PreRender(object sender, EventArgs e)

    private void AddFooterRow(RadGrid grid)

        if (grid != null)
        {
            GridItem[] footerItems = grid.MasterTableView.GetItems(GridItemType.Footer);

            if (footerItems.Count() == 1)
            {
                GridTFoot foot = footerItems[0].Parent.Controls[0].Parent as GridTFoot;

                for (int i = 0; i < foot.Controls.Count; i++)
                {
                    GridFooterItem item = foot.Controls[i] as GridFooterItem;

                    if(item != null)
                    {
                        lastFooterPos = i;
                        break;
                    }
                }

                GridFooterItem existingFooter = foot.Controls[lastFooterPos] as GridFooterItem;
                GridFooterItem newFooterItem = new GridFooterItem(grid.MasterTableView, 0, 0);

                foreach(TableCell fc in existingFooter.Cells)
                {
                    TableCell newFooterCell = new TableCell();
                    newFooterCell.Text = "allo";
                    newFooterItem.Cells.Add(newFooterCell);
                }

                foot.Controls.AddAt(lastFooterPos + 1, newFooterItem);
            }
        }
    }

当然，如果您需要更高的精度，请询问。感谢您的帮助。

在对 Telerik 文档进行了一些搜索之后，我很确定这不仅仅是可能的。例如，在这个问题中，Telerik 管理员明确指出“ RadGrid 是数据绑定控件，它的项目是根据其数据源中的记录创建的并显示数据源数据。因此，为了在网格中添加新行，您需要在其数据源中添加新记录并重新绑定网格。 "

因此，为了解决我的问题，我决定删除网格上的页脚并在下面添加一个全新的网格，我将绑定到DataTable我将通过Page_Load事件处理程序中的代码创建的虚拟对象。这些值要么通过 Javascript 在客户端确定，要么简单地注入到该虚拟表的行中。

如果有人找到更优雅的解决方案，我仍然有兴趣了解它！然而，现在，工作必须向前推进。
