I am programatically creating (2) controls in code-behind ("btn" and "pnl"). btn is a custom control that hides another control (clientside). When using these as static controls, it works great, however, here is the code for the code-behind.

code begin:

Button btn = new Button();


Panel pnl = new Panel();


btn.ControlToToggle = pnl;

end code

Everything is great except the ControlToToggle when a control is created programatically.

Because (pnl) hasn't been rendered yet, btn.ControlToToggle doesn't see a control on the page and give "Object not set to an instance..."

I have had the same problem in the past working with other "built in" controls.

My question is: Is there a way to render a programatically created control to the page before it is posted back to the client?

Thanks

You would probably need to add controls to Controls collection before the logic works (does it serach for Page.Controls in ControlToToggle?)
