CSS Friendly Control Adapters + GridView + Update Panel = Problem
Hi everyone,I'm using a gridview control that's bound to an object data source. I have a couple of controls to filter the data in the gridview, and I'm able to sort and page through the data. Placing it in an UpdatePanel gives me partial page rendering and the whole page doesn't refresh - Great. Expected behaviour and it all works very well. However, introduce a Control Adapter into the mix (http://www.asp.net/cssadapters/) and Update Panel doesn't work at all - with the whole page refreshing. If anybody can offer any help, I'd be very grateful. I want both A...
CSS Adapted Treeview control displaying all nodes on page load
Hi. I have decided to use the adapted Treeview control for a project I am working on at the moment. All the control will do is display lists of categories and sub categories, and eventually products at the bottom level. When I load my page up, everything is displayed, rather than the top level nodes. I have taken the control out and placed it in a small test project and exactly the same thing is happening. I am not using the App_Themes folder, I am linking directly to the CSS and Javascript files, and my CSS Treeview Adapter is in it's own .dll file. My code is below. If anyone could giv...
Is CSS Control Adapters compatible with WebPart and WebPartZone controls?
Both WebPart and WebPartZone ultimately derive from WebControl, so it seems like this would work, but before I got into it deeply, was curious if anyone had tried it and if there are any issues? I don't think there is an esay way to make it works. This was a reply from Scott Guthrie: Unfortunately I don't think there is a super easy way to override WebParts -- since some of the layout does assume tables (since the CSS to-do this positioning with divs isn't super easy). We are going to look at whether it is possible to build another control adapter for webparts in the f...

Problems with Treeview control
1. I haven't been able to trap any of the tree view events when navigating in the tree on a master page/content page layout. Specifically, I want to be able to retrieve the selected node in code after it has been clicked - whenever I try to do this from the loaded content page the selected node value returns "nothing". I assume this is because the content page is actually reloading the master page in a postback so that the clicked value is no longer available after the postback. When I try to put code in the selection changed event of the master page, that event...
