I use a prometheus combobox. I use header and item templates. I have set EnableLoadOnDemand = true. I use the ItemsRequested eventhandler.
The control is on the page initially, but in a hidden panel (so not rendered). After a postback the panel is visible. This combox control looks ok, but the dropdown does not work at all.
The dropdown does work if the control is initaly rendered.
Is there any work around to this situation, such as registering javascript during the ajax callback?
