Up to your questions
1. At present the RadFormDecorator skips decorating controls such as RadNumericTextBox and RadDatePicker, as they have their own skinning. Yet, you are correct to expect that those skins should "match" - while they not. We will be taking action in this direction into "alig
ning" the look of the two products when the same skin is used.
2. As for problem #2 it could be from using an older Telerik.Web.UI.dll - where the sliding panes are [direct] children of the <body>
element, and not of the splitter. In the current version of the sliding panes are children of the splitter - and they should work fine if you use DecorationZoneID property. To make sure it is so, we tested with a sample page and it worked fine with the Q3 2008 release. My advice would be to wait till the coming Q3 SP1 to be released in 1 or 2 days from now, and give it a try.
3. You can easily achieve the effect you are looking for - that is, controlling the skin of all Telerik controls on a page using a single control. It is only that RadFormDecorator is not this control :) As of Q3 we introduced a special new control called RadSkinManager
. Setting its Skin property causes the skin to be applied to any other Telerik control.
