同一页面中的多个 ModalPopupExtender 存在问题，每个都需要验证。由于某种原因，我没有看到，第二次验证触发（即显示错误消息），但回发没有被取消，而且 Page.IsValid 在代码隐藏中为真。在第一个 MPE 上，回发被取消，我们从未遇到过代码隐藏。

模态的标记：

服务器端代码：

            Int32.TryParse(ddlCategory.SelectedValue, out newCategoryId);
            if (indicator.Category.KpiCategoryId != newCategoryId)
            {
                indicator.Category = KpiCategoryFactory.GetById(newCategoryId);

嗬！看看再看看，最后发现我没有在第二个弹出窗口中设置验证组。

我需要回去睡觉了。

抱歉，如果有人浪费时间看这个。
