how to get the selected connection node object of

I'm adding some options for the Connection Node in the server explorer for my VS extension. For one of the menu options that I have added I need to get the connection string of the very selected connection, So I have tried this by adding some code in the BeforeQueryStatus event and also in the command handler method. But looks like I'm missing something since every time I want to get an Instance of the DataViewHierarchyAccessor I always get a null value. Although if I do the same thing but in a lower level node works fine. I have used the following code with no luck:

IVsDataExplorerNodeSelection nodeSelection = (IVsDataExplorerNodeSelection)Package.GetGlobalService(typeof(IVsDataExplorerNodeSelection));

IVsUIHierarchy hierarchy = Marshal.GetTypedObjectForIUnknown(hierarchyPtr, typeof(IVsUIHierarchy)) as IVsUIHierarchy;

Has anybody done something similar for the Connection Node of the Server Explorer Window?

Update:

Looks like I got some progress on this, I just tried this:

EnvDTE80.DTE2 _applicationObject = GetDTE2();
UIHierarchy uih = _applicationObject.ToolWindows.GetToolWindow("Server Explorer") as UIHierarchy;
Array selectedItems = (Array)uih.SelectedItems;
if (null != selectedItems)
    {
        foreach (UIHierarchyItem selItem in selectedItems)
        {
            SelectedItem prjItem = selItem.Object as EnvDTE.SelectedItem;
            string name = prjItem.Name;
        }
    }

Now my question is if there's a better type to cast the list of selectedItems? instead of EnvDTE.SelectedItem.

Thanks in advance.

Marking my question as answered since the code that I posted did the trick.

EnvDTE80.DTE2 _applicationObject = GetDTE2();
UIHierarchy uih = _applicationObject.ToolWindows.GetToolWindow("Server Explorer") as UIHierarchy;
Array selectedItems = (Array)uih.SelectedItems;
if (null != selectedItems)
{
    foreach (UIHierarchyItem selItem in selectedItems)
    {
        SelectedItem prjItem = selItem.Object as EnvDTE.SelectedItem;
        string name = prjItem.Name;
    }
}
