推荐答案

在更新面板旁边，我放置了很多面板.
现在我要显示面板.，请给我一个解决方案.
Panel是服务器端控件，可以使用其ID在服务器端直接访问.

因此适用于:

nside the update panel i placed lot of panel.
now i want to show the panel ., please give me a solutuion.,
Panel is a server side control that can be accessed directly on server side using it''s ID.

Thus for:

<asp:Panel ID="Panel1" runat="server"> 

做:

Do:

Panel1.Visible = true; // to show panel
Panel1.Visible = false; // to hide panel

要添加-在更新面板中还是不在更新面板中都没有关系.

To add on - it does not matter if it is in or out of Update Panel. Update panel is just a region defined for partial update if needed.

TabContainer1.FindControl("tab3").FindControl("P" + i.ToString()).Visible = true;

TabContainer1.FindControl("tab3").FindControl("P" + i.ToString()).Visible = true;
