Hello Telerik Team,

I'm developing my web-app based on RadTabStrip/MultiPage load on demand pageviews. I was happy with the end-result until I realised that each time I click a tab, ALL the pageviews are reloaded, which means ALL the User Controls are reloaded too, which is not good!

Also, I can't use the RenderSelectedPageOnly option on MultiPage cause I cancel ajax requests for tabs whose corresponding pageviews have been loaded.

So, the desired behavior is :

1) Load the user controls on demand, so I can navigate through them without doing unnecessary postback.

2) When I click on a tab which is not already loaded, I just want his appropriate pageview loaded, keeping the others pageviews unaffected.

Is it possible to do that? If so, How can I modify your online demo to achieve the desired behavior?

Thanks in advance!

Well, let me explain exactly the problem that I'm facing.

Let's say I'm running my web-app with ten tabs loaded. So, with the care of RadTabStrip/MultiPage load on demand pageviews, I can navigate between these ten tabs without causing postback to the server, right? BUT, what if I, in one of my tab, want to do a simple ajax async-postback initiated by one of the ten usercontrols? Well, for this simple ajax request, and based on the MultiPage, the server will have to recreate ALL the ten user controls, and just after that, treating my ajax request. It's by the way too slow and not acceptable

I think you can better understand my problem now. The fact that I have to reload all the usercontrols simply to execute a simple ajax request, wich normally take a matter of a second, and now take about 5-10 seconds, is certainly not a desired behavior.

I perhaps find a "solution" to that problem, which is by using a PlaceHolder to hold the usercontrols instead of a RadMultiPage, but by taking this path I loose the Load on Demand benefit on the client...

Do you know a better alternative?

Thanks again!
