Hello,

I've built a "portal" interface, combining dynamic TabStrip and RadDockLayout/Zone/Dock controls, fed from a database.

When the user clicks on a different tab, I want to show a different set of docks.  On the postback, though, the docks from the soon-to-be-previous tab are still in viewstate and get reattached to their Zones.  I added a method to clear them:


The .Clear() method isn't working.  It just plain doesn't clear the Zone.  The Docks are still there, before and after the .Clear() call.

I changed to the (commented out) .Closed = True option, but that seems slow and klunky to me. 

a) is there a reason that .Clear() wouldn't work?  I do realize I'm using a readonly collection to access them, but RegisteredZones only returns readonly. 

b) is there a better way of clearing all the Docks in a Layout? 

Thanks!

Hi Rob,

Regarding your questions:

1. The Clear() method is not working, because the Collection of RadDocks is, as you said, read-only and cannot be modified.

2. There is no other way to clear the docks in the layout. To improve the performance, my recommendation is, when you change the tab, to [re]create the set of docks that are associated with the current tab. This way only the docks that can be seen from a certain tab, will be present on the page and the others will not be there.
