FindControl

[Ravikanth[MVP]]

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?

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,
