How to dynamically create extender controls


Hi all,

Ok thera's a couple of post on this already but I can't figure out a solution. I'm dynamically adding a calendar extender like so:

CalendarExtender CE = new CalendarExtender();
CE.ID = "ce" + parameter.Name;
CE.TargetControlID = TB.ID;
CE.PopupButtonID = IB.ID;
CE.Format = "dd MMMM yyyy";

When a postback occurs I get the following error:

Extender control 'ceDateFrom' is not a registered extender control.
Extender controls must be registered using RegisterExtenderControl() before calling RegisterScriptDescriptors().
Parameter name: extenderControl

Does anybody know how to resolve this?
