I'm adding a Panel to a Panel serverside, then try to access the second panel using FindControl, but it returns null - can anyone tell me what I am missing?
Panel p1 = new Panel();
Panel p2 = new Panel();
p2.ID = "Panel2";
p1.Controls.Add(p2);
// This returns null
Panel tempPanel = (Panel)p1.FindControl("Panel2");
I can see in the 'Watch' window that p2 has been added and has the ID 'Panel2'. FindControl returns null
Find control will work when you add the parent control on Page.
Try this
Panel p1 = new Panel();
Panel p2 = new Panel();
Panel p3 = new Panel();
Panel p4 = new Panel();
Panel p5 = new Panel();
p2.ID = "Panel2";
p3.ID = "Panel3";
p4.ID = "Panel4";
p5.ID = "Panel5";
p1.Controls.Add(p2);
p1.Controls.Add(p3);
p1.Controls.Add(p4);
p1.Controls.Add(p5);
//Add Parent Panel on Page
this.Controls.Add(p1);
Panel tempPanel = p1.FindControl("Panel2") as Panel;
