I have 2 identical AutoCompleteExtender's - one is in the Insert mode of my DetailsView, which is the default mode, and one is in the Edit mode. There is also another DetailsView, which only shows when a Checkbox is ticked (and the page posts back), which also hides the previous one.
When the mode is Insert, there are no issues at all, even when ticking the checkbox to hide the DetailsView with the AutoCompleteExtender in and show the other one (which has no AJAX controls btw). But when the mode changes to Edit, and the user ticks the checkbox to change to the other details view (with no ajax), I get this error:
Extender control 'autoNom' is not a registered extender control. Extender controls must be registered using RegisterExtenderControl() before calling RegisterScriptDescriptors(). Parameter name: extenderControl
Any ideas guys?
Thanks
