Hi

FindControl method is to locate a control with an ID
property of <<Control>> on the containing page.

Check ChannelPanelId after adding the Display Panel.

Is there no way of finding the embedded panel prior to
rendering?

I know I am doing or understanding something wrong. This
is a code snipet from a server control that accesses the
MCMS channel structure to build a dynamic cascading menu
system. While this is not the actual code (too extensive)
it performs the key function and provides the same
unsatisfactory results:

Channel current = CurrentContext.Channel;
Panel Display = new Panel();

foreach(Channel subchannel in current.Channels)
{
Panel channelPanel = new Panel();
channelPanel.ID = subchannel.Name;
Display.Controls.Add(channelPanel)
}

string chName = current.Channels[0].Name;
Panel foundPanel = Display.FindControl(chName);

It seems that since there are 3 subchannels to current,
foundPanel should return the first Panel added in the
foreach loop. It doesn't. It returns null. Why?

Thanks.

Hello Tim,

I moved the following codes into page_load and the pane could be found now.

Display = new Panel();
this.Controls.Add(Display);
String[] ids = new String[3];
ids[0] = "panel1";
ids[1] = "panel2";
ids[2] = "panel3";

foreach(Channel subchannel in current.Channels)
{
Panel channelPanel = new Panel();
channelPanel.ID = subchannel.Name;
Display.Controls.Add(channelPanel)
}

Also, I defined Dispaly as a global varialbe as other controls.

Please test it and let me know whether it is what you needed.

Best regards,
