I never seem to be able to successfully search through these forums (a timeout always occurs) so not sure what I'm doing wrong there, so sorry if this is a really obvious question. Am currently using DNN framework 4.9.5

I work for a software company and we build our own DNN modules. When those modules use multiple ASCX pages though, and I log in as Host or Admin, typically on the subsequent pages I lose the ability to add further modules to the page, such as a Text / HTML module, as control over the panes seem to disappear. For example, we have built a DNN module that allows online customers to a site to book on a Tour that might run daily at 10am. There are several steps involved in booking the tour, and therefore our Tour Module has 6 different ASCX pages within the module. If I go to any of the pages other than the initial one, I can no longer directly access the Content Pane, and therefore cannot add in a TEXT / HTML module to the top of the SearchResult.ascx page.

Ultimately what I want to be able to do is add a TEXT / HTML component to the top of the Content Pane, on any or all of the ascx pages contained within the module. Is this doable? The centent within that Text / HTML page might be different depending on what step the user is at in the Tour booking process and needs to be customized per site, meaning our Tour module is purchased by several clients, and nobody ever wants the same wording to appear

Bill's response would be the way to go.  But to acheive your other desired resut. (text changing a top of each step) you would either have to build that into the module itself. (could be defined in the module settings.  Step1Text, Step2Text etc) or you would have to create a separate module and use inter module communication.  I'd recommend just adding it to your module.  Much easier to control and distribute. (instead of 2 modules)
