C# 引导选项卡下的多个GridView

我有一个aspx页面，其中包含多（9）个asp:GridView，每个页面位于单独的引导选项卡下。（下面的代码示例）

这会导致在服务和呈现页面之前执行每个asp:GridView和关联的asp:DataSource

由于大多数用户只能查看一个或两个选项卡，这感觉太沉重，效率低下

理想情况下，我正在寻找一个神奇的修复程序，只有在选中该选项卡的情况下，它才会对GridView、DataSource和sql存储过程进行操作，但我担心我已经陷入困境

有什么建议吗

如果你能找到办法，我很想知道怎么做。恐怕我没有。我不得不搁置这个项目，没有继续进行下去。然而，我的方向是用中继器控件替换导航选项卡，然后在相关的ajax部分进行交换。但我没有实施它，因此这种方法可能存在一些问题，我还没有意识到：(
