Hello 

what's my mean? 
as we know, we can set skin in QueryString via SkinSrc or Container Src ( for container)
by this way, we must add these params into QueryString. 

could we inject skin and container in HttpModule or Page events (such as Page_Init) ? 
for example :

on the page settings: 
the Skin of Page A is : skinA
the Container of Page A is containerA.

when we open page A, i hope we can change skinA to SkinB, and change containerA to containerB.

NOTE: one page can has many modules , but each module will has  its own container. 
how to set container dynamically when page is running?

i have searched on the google, dotnetnuke, dnncreative etc...
but there is no good solution.

please advise. 
any ideas will be appreciated. 
 

your link is not the solution. how to change skin.css and container.css? because different skin has its own skin.css. your way is only changed layout. my current idea is change DNN sources and it will support dynamic inject skin.
