Drag and drop nodes between a RadTreeView and a RadPanelBar?

I'm working on a report-configuration web app. I have the properties of a business object's members represented by child nodes in a RadTreeView and would like to be able to drag those nodes to a RadPanelBar. The PanelBarItems would then be populated by user controls I have already made that represent reporting options for each of the "properties" (i.e. nodes) that were selected from the TreeView. (the PanelBarItems will then be used for configuring a report).

Is it possible to drag and drop nodes from a RadTreeView to a RadPanelBar?

RadWindow Ajax Panel - Open in Code Behind

I am currently creating and opening a RadWindow in the code behind using the RadWindowManager. The RadWindow opens without issue until I add a RadAjaxPanel. I was wondering how I can still get the RadWindow to open with a RadAjaxPanel. Below is the code I have:

ASP.NET:

<telerik:RadAjaxLoadingPanel ID="LocationsLoadingPanel" runat="server" Transparency="30" Skin="Vista"></telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxPanel ID="LocationsPanel" runat="server" LoadingPanelID="LocationsLoadingPanel">

<telerik:RadTreeView ID="LocationsTreeView" runat="server" EnableDragAndDrop="true" MultipleSelect="true" EnableDragAndDropBetweenNodes="true"

AllowNodeEditing="true" OnContextMenuItemClick="LocationsTreeView_ContextMenuItemClick" OnClientContextMenuItemClicking="onClientContextMenuItemClicking"

OnClientContextMenuShowing="onClientContextMenuShowing" OnNodeEdit="LocationsTreeView_NodeEdit"

OnNodeDrop="LocationsTreeView_NodeDrop" OnClientNodeDropping="onNodeDropping" OnClientNodeDragging="onNodeDragging">

<ContextMenus>

<telerik:RadTreeViewContextMenu ID="MainContextMenu" runat="server">

<Items>

<telerik:RadMenuItem Value="Rename" Text="Rename ..." Enabled="true" ImageUrl="images/icons/edit_48.png"

PostBack="false">

</telerik:RadMenuItem>

<telerik:RadMenuItem IsSeparator="true">

</telerik:RadMenuItem>

<telerik:RadMenuItem Value="addLocation" Text="Add Location" ImageUrl="images/icons/add_16.png">

</telerik:RadMenuItem>

<telerik:RadMenuItem Value="editDetails" Text="Edit Details" PostBack="true" />

</Items>

<CollapseAnimation Type="none" />

</telerik:RadTreeViewContextMenu>

</ContextMenus>

</telerik:RadTreeView>

</telerik:RadAjaxPanel>

<telerik:RadWindowManager ID="locationRadWindow" runat="server" />

C#:

RadWindow window1 = new RadWindow();

window1.NavigateUrl = "http://www.google.com";

window1.VisibleOnPageLoad = true;

window1.Width = 500;

window1.Height = 300;

window1.VisibleOnPageLoad = true;

locationRadWindow.Windows.Add(window1);

Thanks!

RAD Grid Row Hovering

I was curious if anyone has been able to do something similar to the RAD Menu Mega Drop Down (http://demos.telerik.com/aspnet-ajax/menu/examples/megadropdown/defaultcs.aspx) on hovering over a row or cell from a RAD Grid? A customer had suggested something similar to a Netflix style of hovering over a row to see a well-formatted and expanded detail version of the data.
