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.NET

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

Do:

C#

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

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.

ok, In my first page i have a dropdown contains numbers from 1 to 5.
if i select any value from that drop down, based on the value the panel
should display in second page.
if i select i one means, first panel should display. vice versa.

Panel:
I have kept two panel inside in Update Panel. Within the panel
i have a dropdown and two text boxes.

Panel panel = (Panel)TabContainer1.FindControl("tab3").FindControl("P" + i.ToString());

string rt= panel.ID;

// i tried this one to get the panel id. i got.t but i want to show the
corresponding panel.
if i put rt.visible=true; // it is an error.
i tried to convert into Panel// also an error.

what to do?
